use your z-score table. what percentage of scores (i.e., of a gaussian distribution) is between -1.96 and 1.96 z-scores? you don't have to put the % sign.

Answers

Answer 1

Approximately 95% of scores lie between -1.96 and 1.96 z-scores. This is because the area under the standard normal distribution curve between these two values is approximately 0.95.

To calculate this, first calculate the area under the standard normal distribution curve between -1.96 and 1.96. This can be done by using a Z-score table, which provides the area under the curve to the left of a given value. To calculate the area between -1.96 and 1.96, subtract the area to the left of -1.96 from the area to the left of 1.96. This is approximately 0.95.

Since the total area under the curve is 1, this implies that approximately 95% of scores lie between -1.96 and 1.96 z-scores. This is commonly known as the "95% Rule," and it is a useful way to quickly estimate the amount of scores that are within a certain range.

It is important to note that this calculation is only an approximation, as the exact value depends on the actual values that are used. Therefore, it is important to use a Z-score table with more accurate values if more precision is needed.

Answers

Answer:

Step-by-step explanation:

The total revenue from selling 300 tickets for £5 each is:

300 x £5 = £1500

The profit will be the difference between the total revenue and the cost of prizes:

£1500 - £400 = £1100

The amount of profit that goes to Charity A is:

55% x £1100 = £605

Step-by-step explanation:

Answer:

Step-by-step explanation:

Graphing the point (0, 2) means plotting a point at the coordinates where the x-axis is located at 0 and the y-axis is located at 2. This means that the point would be located at the upper part of the y-axis.

On the other hand, graphing the point (2, 0) means plotting a point where the x-axis is located at 2 and the y-axis is located at 0. This means that the point would be located on the x-axis to the right of the origin.

In general, the order of the coordinates in an (x, y) pair represents the horizontal and vertical position of the point, respectively. Thus switching the order of the coordinates changes the position of the point on the coordinate plane.

The purpose of filling out a W-4 is to make it easier for individuals to meet their tax liability by
paying income taxes as they earn income. Paying anticipated taxes from each paycheck
reduces the amount an individual owes when filing taxes and can even result in a tax refund.
To guarantee or increase the refund, individuals sometimes claim fewer allowances (to have
more income tax withheld) or request a specific additional amount to be withheld from each
paycheck.
Daniel's employer will automatically deduct taxes from Daniel's pay using the information on
the W-4 form that Daniel completed on his first day. From his W-4 form, Daniel's employer
determined that $75 needs to be withheld from each of Daniel's weekly paychecks, totaling
$3,900 for the year.
Compare Daniel's tax liability from part B, question 3, with the total amount withheld from his
check: $3,900 for the year. If Daniel wants a refund when he files his taxes, should he have
filled out his W-4 differently? Explain your reasoning.

Answers

Answer:

To determine if Daniel should have filled out his W-4 form differently to receive a refund, we need to compare his tax liability with the total amount withheld from his paychecks for the year.

If Daniel's tax liability for the year is less than $3,900, he will receive a refund when he files his taxes. If his tax liability is more than $3,900, he will owe additional taxes when he files his taxes.

If Daniel's tax liability is exactly $3,900, he will neither owe additional taxes nor receive a refund when he files his taxes.

Therefore, to determine if Daniel should have filled out his W-4 form differently, we need to compare his tax liability with $3,900.

If Daniel's tax liability from part B, question 3, is less than $3,900, he will receive a refund when he files his taxes, as the total amount withheld from his paychecks is more than his tax liability. In this case, Daniel may want to consider filling out his W-4 form differently to reduce the amount withheld from his paychecks and increase his take-home pay.

On the other hand, if Daniel's tax liability from part B, question 3, is more than $3,900, he will owe additional taxes when he files his taxes, as the total amount withheld from his paychecks is less than his tax liability. In this case, Daniel may want to consider filling out his W-4 form differently to increase the amount withheld from his paychecks and reduce the amount he will owe when he files his taxes.

If Daniel's tax liability from part B, question 3, is exactly $3,900, he will neither owe additional taxes nor receive a refund when he files his taxes, and his W-4 form is correctly filled out for his tax situation.

In summary, whether or not Daniel should have filled out his W-4 form differently to receive a refund depends on his tax liability compared to the total amount withheld from his paychecks. If his tax liability is less than the total amount withheld, he may want to reduce the amount withheld to increase his take-home pay. If his tax liability is more than the total amount withheld, he may want to increase the amount withheld to reduce the amount he will owe when he files his taxes. If his tax liability is exactly equal to the total amount withheld, his W-4 form is correctly filled out for his tax situation.

the coefficient of correlation is a useful measure of the linear relationship between two variables. true false

Answers

The statement is true.

The coefficient of correlation, also known as the Pearson correlation coefficient, is a measure of the strength and direction of the linear relationship between two variables. It ranges from -1 to 1, with a value of -1 indicating a perfect negative correlation, a value of 0 indicating no correlation, and a value of 1 indicating a perfect positive correlation.

The coefficient of correlation is useful in many applications, including research, business, and finance. It allows us to quantify how closely related two variables are, which is important when analyzing data and making predictions.

For example, in finance, the correlation coefficient can be used to measure the degree of correlation between the returns of two assets, which is important when building diversified portfolios. It is important to note, however, that the coefficient of correlation only measures the strength and direction of the linear relationship between two variables.

It does not indicate causation, nor does it capture any non-linear relationships that may exist between the variables. Therefore, it should be used in conjunction with other analytical tools to fully understand the nature of the relationship between the variables.

How many multiples of 2 are there between 176 and 389

Answers

There are 107 multiples of 2 between 176 and 389.

The first multiple of 2 within the range is the smallest multiple of 2 that is greater than or equal to the lower endpoint, which is 176. To find this, we divide 176 by 2:

176 ÷ 2 = 88

So the first multiple of 2 within the range is 88.

The last multiple of 2 within the range is the largest multiple of 2 that is less than or equal to the upper endpoint, which is 389. To find this, we divide 389 by 2:

389 ÷ 2 = 194.5

Since we are only interested in whole numbers, we round 194.5 down to the nearest integer, which is 194.

So the last multiple of 2 within the range is 194.

Now that we know the first and last multiples of 2 within the range, we can count how many multiples of 2 exist between them. To do this, we subtract the first multiple from the last multiple and add 1:

194 - 88 + 1 = 107

Therefore, there are 107 multiples of 2 between 176 and 389.

Step-by-step explanation: To find the perimeter of the room without the door, we need to add up the four sides. Using the simplified expression for the perimeter, which is 2(4x+1) + 2(3x+6), we can simplify further by distributing the 2:

2(4x+1) + 2(3x+6) = 8x + 2 + 6x + 12

m ∠ 1 = ( 7 x − 21 ) ° and m ∠ 2 = ( − 5 x + 75 ) ° , what is m ∠ 1 ?

Answers

The measure of ∠1 is 117° before that we have to find out the angle of x, the values are in degrees.

What is an angle?

An angle is the geometric measure of the space between two intersecting lines or planes, usually expressed in degrees, radians, or other units of measurement.

Since the sum of the measures of angles in a triangle is 180°,

m∠1 + m∠2 + m∠3 = 180°

putting the given values:

(7x - 21)° + (-5x + 75)° + m∠3 = 180°

Simplifying the above equation,

2x + 54° + m∠3 = 180°

Subtracting 54° from both sides, we get:

2x + m∠3 = 126°

We know that ∠3 is a right angle, which means its measure is 90°. Substituting this value, we get:

2x + 90° = 126°

Subtracting 90° from both sides, we get:

2x = 36°

Dividing both sides by 2, we get:

x = 18°

Now that we know the value of x, we can substitute it into the expression for m∠1:

m∠1 = (7x - 21)° = (7 x 18 - 21)° = 117°

Therefore, the measure of ∠1 is 117°.

The measure of angle 1, we need to use the given equation that relates angle 1 to variable x. The equation is

[tex] m ∠ 1 = ( 7 x − 21 ) °[/tex].

the measure of angle 1 is 35 degrees.

This means that the measure of angle 1 is equal to 7 times the value of x minus 21 degrees.
However, we are not given the value of x directly. Instead, we are given the measure of angle 2 in terms of x. The equation for angle 2 is

[tex] m ∠ 2 = ( − 5 x + 75 ) °[/tex].

This means that the measure of angle 2 is equal to negative 5 times the value of x plus 75 degrees.
We can set these two equations equal to each other because angle 1 and angle 2 are vertical angles and therefore congruent. This gives us the equation:
[tex]7x - 21 = -5x + 75[/tex]
We can simplify this equation by adding 5x to both sides:
[tex]12x - 21 = 75[/tex]
Then, we add 21 to both sides:
[tex]12x = 96[/tex]
Finally, we divide both sides by 12:
[tex]x = 8[/tex]
Now that we have found the value of x, we can plug it into the equation for angle 1 to find its measure:

5. The total number of ways to make two pizzas are 523,504

6. The same value that the boy claims in the advertisement.

What is a probability?

A subfield of statistics known as probability studies random events and their likelihood of happening.

1. There are 11 toppings and each topping can be either included or excluded from a pizza, there are 2 choices for each topping. Therefore, there are 2^11 = 2048 ways to make one pizza. For two pizzas, there are 2048*2048 = 4194304 ways to choose the two pizzas.

2. For one pizza with up to five toppings, we can use combinations to determine the number of ways to choose toppings. Since we have 11 toppings to choose from and can choose up to 5, the number of ways to choose is:

C(11, 1) + C(11, 2) + C(11, 3) + C(11, 4) + C(11, 5) = 11 + 55 + 165 + 330 + 462 = 1023

3. If the two pizzas are identical, there is only one way to build the two pizzas.

4. If the two pizzas are different, we need to choose 2 of the 1023 possibilities from problem 2. Since order doesn't matter, we use combinations, and the number of ways to choose is:

C(1023, 2) = 523,503

5. The total number of ways to make two pizzas with up to five toppings each is the sum of the answers from problems 3 and 4:

6. The number 10242 is equal to 1,048,576. This is the same value that the boy claims in the advertisement. Therefore, the boy's claim is valid only if the pizzas can have up to 11 toppings each, not up to 5 as advertised.

Assume that TDW Corporation (calendar year-end) has 2022 taxable income of $650,000 for purposes of computing the §179 expense. The company acquired the following assets during 2022: (Use MACRS Table 1, Table 2, Table 3, Table 4 and Table 5. ) Asset Placed in Service Basis Machinery September 12 $ 2,270,000 Computer equipment February 10 263,000 Furniture April 2 880,000 Total $ 3,413,000 a. What is the maximum amount of §179 expense TDW may deduct for 2022?

Answers

The maximum amount of §179 expense TDW may deduct for 2022 is $257,000.

To determine the maximum amount of §179 expense that TDW Corporation can deduct for 2022, we first Add up the cost of all the assets acquired in 2022:

$2,270,000 (machinery) + $263,000 (computer equipment) + $880,000 (furniture) = $3,413,000

Now we determine the amount of the §179 deduction limit for the tax year.

For tax year 2022, the §179 deduction limit is $1,050,000.

Check if the cost of the assets exceeds the §179 deduction limit.

Since the cost of the assets ($3,413,000) is greater than the §179 deduction limit ($1,050,000), we need to calculate the phase-out limit.

Now we determine the phase-out limit.

For tax year 2022, the phase-out limit is $2,620,000.

Calculate the §179 expense deduction.

Since the cost of the assets ($3,413,000) is greater than the phase-out limit ($2,620,000), we need to reduce the §179 deduction by the excess over the phase-out limit.

The excess over the phase-out limit is $793,000 ($3,413,000 - $2,620,000).

The §179 expense deduction is the lesser of the §179 deduction limit and the cost of the assets reduced by the excess over the phase-out limit.

The §179 expense deduction is $1,050,000 - $793,000 = $257,000.

what is circle ?

A circle in geometry is a closed object made up of all points in a plane that are equally spaced out from a specific point known as the centre. The diameter of a circle is the distance through its centre; the radius is the distance from any point on the circle to that point. Any three locations that are located on a circle can be used to describe it, in addition to its centre point and radius. A circle's circumference, also known as its perimeter, can be calculated using the formula C = 2r, where r denotes the radius and is a mathematical constant roughly equivalent to 3.14. The equation A = r2 determines the area of a circle.

given

We must deduct the area of triangle OAB (the sector) from the area of trapezium ABCD in order to determine the area of the shaded zone formed by points ABDC inside circle sector OAB.

Finding the sector's area is the first step. The sector's central angle is 75 degrees, or (75/360) of the complete circle. Hence, this is the sector's geographic scope:

(75/360)r2, where r is the circle's radius.

Inputting r=4cm results in:

(75/360)π(4)² = (5/12)π cm²

The area of the trapezium must then be located. Finding the height of the trapezium, which is the separation between lines AB and CD, is necessary to do this.

Using the Pythagorean Theorem, the following can be discovered:

h² = (OA)² - (CA) (CA) ²

h² = 4² - 3²

h = √7 cm

The trapezoid's surface area is:

(1/2)(AB+CD)

h = (1/2)(6+4)

(√7) = 5√7 cm²

Lastly, we can calculate the area of the darkened area by deducting the sector's area from the trapezoid's area:

Percentage change is the relative difference between two values expressed as a percentage of one of the values, where the value of the latter is used as the reference point.

It can be calculated by using the following formula:

Percentage change = ((new value - old value) / old value) x 100

Given the birth rate of a nation in 1990 as 20 and the birth rate in 2000 as 13, the percentage change can be calculated as follows: Percentage change = ((13 - 20) / 20) x 100= (-7 / 20) x 100= -0.35 x 100= -35%

Hence, the percentage change is -35%.

a continuous random variable x is normally distributed with a mean of 0 and a standard deviation of 1. the probability of an observation that lies within the range of -1.0 < x <1.0 is:

Answers

a continuous random variable x is normally distributed with a mean of 0 and a standard deviation of 1. the probability of an observation that lies within the range of -1.0 < x <1.0 is 0.6827.

       The explanation for normal distribution is described by two parameters, the mean (μ) and the standard deviation (σ).

         A continuous random variable X that is normally distributed has the probability density function, (X is a normally distributed variable):

                   f(x)=1σ√2π×e−12((x−μσ)2)

        A normal distribution with a mean of 0 and standard deviation of 1 is called standard normal distribution or Z-distribution. The probability for the standard normal distribution can be found using the standard normal distribution table.

   In this case, we have a continuous random variable x which is normally distributed with a mean of 0 and a standard deviation of 1. We are asked to find the probability of an observation that lies within the range of -1.0 < x < 1.0.

  In other words, we want to find: P(-1.0 < x < 1.0)

  To do this, we need to transform the interval (-1.0, 1.0) to a standard normal distribution as follows:

             Z=(X−μ)/σ = (X−0)/1

                              = X

   Next, we use a standard normal distribution table to find the probability for Z as follows:

             P(-1.0 < x < 1.0) = P(-1 < Z < 1)

                                      = P(Z < 1) - P(Z < -1)

    From the standard normal distribution table,

    We have P(Z < 1) = 0.8413 and

                   P(Z < -1) = 0.1587

   Therefore: P(-1.0 < x < 1.0) = 0.8413 - 0.1587

                                               = 0.6827

   Thus, the probability of an observation that lies within the range of -1.0 < x < 1.0 is 0.6827.

Answers

Point A is three units left and three units up from the origin, so its coordinates are (-3, 3). Therefore, the correct answer is option 2) (-3, 3).

The topic of coordinate geometry involves the use of the Cartesian plane, also known as the coordinate plane or xy-plane, to graph and analyze relationships between points, lines, and shapes. The plane consists of two perpendicular number lines called the x-axis and the y-axis.

The origin, denoted by the point (0, 0), is the point where the two axes intersect. Points on the plane are represented by ordered pairs of numbers (x, y), where x is the distance from the y-axis and y is the distance from the x-axis. Lines on the plane can be represented by their slope and y-intercept, while shapes like circles, rectangles, and triangles can be graphed and analyzed using their respective formulas.

Original salary of R20 955. 00, with an increase of R6 545. 00 per month.
[2] Original salary of R25 858. 02, with an increase of R1 641. 98 per month

per
month.
14] Original salary of R25 858. 02, with an increase of R1 746. 25 per month. ​

Answers

Jabu's Monthly salary is of R27500.00, with an increase of R1 746.25 per month. Jabu's monthly increase is R1 746.25. The correct answer is option 3.

To find Jabu's previous monthly salary, we can use the formula:

Previous monthly salary = (Annual salary / 12)

Since Jabu's new annual salary is R330 000, his previous annual salary would be:

Previous annual salary = (New annual salary / 1.0635) = (R330 000 / 1.0635) = R310 020.10

Therefore, Jabu's previous monthly salary would be:

Previous monthly salary = (Previous annual salary / 12) = (R310 020.10 / 12) = R25 835.01

To find the monthly increase, we can subtract Jabu's previous monthly salary from his new monthly salary:

Monthly increase = (New monthly salary - Previous monthly salary) = (R27 618.38 - R25 835.01) = R1 783.37

Therefore, Jabu's monthly increase is R1 746.25 (rounded to the nearest cent).

Rami works at a carnival dart game where groups of people try to pop balloons taped to a wall by throwing darts. He records the number of people in each group and the total number of balloons they pop. This graph represents Rami’s data.


How many people were in the group that popped 10 balloons?

Answers

We can see that this corresponds to the point (4, 10). Therefore, there were 4 people in the group that popped 10 balloons.

Describe Correlation?

Correlation refers to the relationship between two variables in a dataset. It is a statistical measure that quantifies the degree to which two variables are related to each other.

There are two types of correlation: positive and negative. Positive correlation exists when the two variables move in the same direction, meaning that as one variable increases, the other variable also increases. Negative correlation exists when the two variables move in opposite directions, meaning that as one variable increases, the other variable decreases.

The strength of the correlation can be measured using a correlation coefficient, which ranges from -1 to +1. A correlation coefficient of +1 indicates a perfect positive correlation, while a correlation coefficient of -1 indicates a perfect negative correlation. A correlation coefficient of 0 indicates no correlation between the two variables.

From the given graph, we can see that there is a positive correlation between the number of people in a group and the total number of balloons they pop. As the number of people in the group increases, the total number of balloons they pop also tends to increase.

We are asked to find the number of people in the group that popped 10 balloons. From the graph, we can see that this corresponds to the point (4, 10). Therefore, there were 4 people in the group that popped 10 balloons.

Use the fundamental counting principle

Answers

As per the fundamental counting principle, the total number of possible outcomes is 24.

To use the fundamental counting principle, we need to first identify the number of choices available for each option. In this case, we have 3 types of shoes, 4 colors, and 2 width options. So, the number of choices for each option is:

3 types of shoes

4 colors

2 width options

To determine the total number of possible outcomes, we multiply the number of choices for each option. This gives us:

Total number of possible outcomes = number of choices for type of shoe x number of choices for color x number of choices for width

= 3 x 4 x 2

= 24

Therefore, there are 24 possible shoe combinations that can be created from the given options.

What is the exact value of side x in the Trina for below? 20in 30 degree and X?

Answers

According to the question, the exact value of side x in the Trina are  34.641016151377546in.

What is value?

Value is an intangible concept that refers to the worth of something, whether it is tangible or intangible. It is based on the perceived benefits and costs associated with the thing in question. Value can be subjective, as different people may place different worth on the same item. Value can also be objective, as there may be a set market price for a certain item.

The exact value of side x in the triangle can be determined by using the law of sines. The law of sines states that the ratio of the length of a side to the sine of its opposite angle is the same for all sides of a triangle.

Therefore, we can set up the following equation:

(20in/sin30°) = (x/sin60°)

Solving for x, we get:

x = 20in×(sin60°/sin30°)

x = 20in×(√(3)/1)

x = 20in×√(3)

What is Exact value?

Where you cannot predict the value, you must be specific. An exact number is a value that can be determined with absolute precision. Counted quantities of objects or sure unit conversions are examples of exact numbers.

The term "approximate number" refers to a number that is close to the precise number, and there is always a difference among exact and approximate numbers. For instance, are exact integers because no approximation is required.

As a result, we can construct the following equation:

(20in/sin30°) = (x/sin60°)

Solving for x, we get:

x = 20in×(sin60°/sin30°)

Simplify the above equation,

x = 20in×(√(3)/1)

Mr. Salinger has 8 packs of seeds. The line plot shows the weight of each pack. Mr. Salinger wants to redistribute the seeds in such a way that each pack weighs the same. What will be the weight of each pack?

Answers

Each pack should weigh 11.5 oz when the seeds are redistributed equally.

Since Mr. Salinger wants to redistribute the seeds in such a way that each pack weighs the same, he needs to find the common weight of all the packs. To do this, he can find the total weight of all the packs and divide it by the number of packs.

Using the line plot, we can see that the weights of the 8 packs are:

12 oz

8 oz

10 oz

10 oz

12 oz

14 oz

10 oz

16 oz

To find the total weight of all the packs, we can add these weights together:

12 + 8 + 10 + 10 + 12 + 14 + 10 + 16 = 92 oz

So the total weight of all the packs is 92 oz.

To find the weight of each pack, we need to divide the total weight by the number of packs:

92 ÷ 8 = 11.5 oz
