The spinner shows has 4 equal sized sections. Jackson spins the spinner 32 times

Answers

Answer 1

The answer of the question based on the probability  that The spinner shows has 4 equal sized sections. Jackson spins the spinner 32 times the answer is 8 times.

What is Event?

A event is any outcome or the set of outcomes of experiment or random process.

An event can be as like as a single outcome or as complex as a combination of the outcomes. For example, flipping a coin and getting heads is an event, as is rolling a die and getting a 6.

The spinner has 4 equal sized sections, then each section has a probability of 1/4 or 25% of being landed on when the spinner is spun.

If Jackson spins the spinner 32 times, we can find the expected number of times each section will be landed on by multiplying the probability of landing on each section by the total number of spins:

Expected number of times to land on each section = (Probability of landing on section) x (Total number of spins)

Expected number of times to land on each section = (1/4) x (32)

Expected number of times to land on each section = 8

Therefore, we can expect each section to be landed on approximately 8 times out of the 32 spins.

The quadrilateral whose vertices are A(2, 3); B(4, -2);C(-1,-4); D(-3, 1) is a square.

What are Quadrilaterals?

Quadrilaterals are four sided polygons which also have four vertices and four angles.

Sum of all the interior angles of a quadrilateral is 360 degrees.

Given A(2, 3); B(4, -2);C(-1,-4); D(-3, 1)

Length of AB = [tex]\sqrt{(4-2)^2+(-2-3)^2}[/tex] = √29 units

Length of BC = [tex]\sqrt{(-1-4)^2+(-4--2)^2}[/tex] = √29 units

Adjacent sides are equal.

So the quadrilateral must be square or rhombus.

Now, find the length of diagonals.

If the diagonals are equal, then it is square. If they are not equal, then it is rhombus.

AC = [tex]\sqrt{(-1-2)^2+ (-4-3)^2}[/tex] = √58 units

BD = [tex]\sqrt{(-3-4)^2+(1--2)^2}[/tex] = √58 units

Diagonals are equal.

So it is a square.

Hence the quadrilateral is a square.

Find the nth term for the following sequence-5,-2,3,10,19

Answers

Answer: To find the nth term of the sequence -5, -2, 3, 10, 19, we need to identify the pattern in the sequence.

Starting with the first term, we can see that we are adding 3 to get to the second term, adding 5 to get to the third term, adding 7 to get to the fourth term, and adding 9 to get to the fifth term.

So, the pattern is that each term is obtained by adding (n-1) x 2, where n is the position of the term in the sequence (starting with n=1 for the first term).

Therefore, the nth term of the sequence is:

-5 + (n-1) x 2

Simplifying this expression, we get:

-5 + 2n - 2 = 2n - 7

So, the nth term of the sequence is 2n - 7.

For the trapezoid given the value for x is obtained as 6.

What is a trapezoid?

A polygon with only one set of parallel sides is called a trapezoid. The parallel bases of a trapezoid are another name for these parallel sides. Trapezoids have two additional sides that are not parallel and are referred to as their legs.

The value for parallel sides of a trapezoid is given as 3x + 2 and 2x - 2.

A line segment divides the trapezoid in half.

The line segment dividing the trapezoid in half measures 15 units.

We know that the line segment dividing the trapezoid in half is also the average of the parallel sides.

So we can set up an equation -

(3x + 2 + 2x - 2) / 2 = 15

Simplifying the left side, we get -

(5x) / 2 = 15

Multiplying both sides by 2/5, we get -

x = 6

Therefore, the value of x is 6.

We can check that this value works by plugging it into the expressions for the parallel sides -

3x + 2 = 20

2x - 2 = 10

So the lengths of the parallel sides are 20 and 10.

Therefore, the average of these is indeed 15, and so the line segment dividing the trapezoid in half has length 15, as given.

Answers

The answer of the question based on the to represent the area of the figure the answer is given below,

What is Rectangle?

A rectangle is four-sided polygon with opposite sides that are parallel and congruent (equal) in the length.

a) The figure is a rectangle with a length of 2x + 3 and a width of x - 2. The area of the rectangle is:

Area = length x width

Area = (2x + 3)(x - 2)

Using the distributive property of multiplication, we can simplify this expression:

Area = 2x² - 4x + 3x - 6

Area = 2x² - x - 6

Therefore, the expression for the area of the figure is 2x² - x - 6.

The figure is a trapezoid with a height of 3 and two parallel sides of length x + y and x - y. average of lengths of the two sides are:

(x + y + x - y)/2 = 2x/2 = x

So, the area of the trapezoid is:

Area = (1/2) x height x (sum of parallel sides)

Area = (1/2)(x)(3)(x + y + x - y)/2

Area = (3/2) x²

Now, we need to subtract the area of the triangle from the trapezoid. The triangle has a height of 3 and a base of y, so its area is:

(1/2)(y)(3) = (3/2)y

Therefore, the expression for the area of the figure is:

Area = (3/2)x² - (3/2)y.

The average number of gallons W of bottled water consumed each year by the consumer can be approximated by W=1.8d+17.48, where d is the number of 2000.

Answers

The average number of gallons of bottled water consumed in the year 2010 is 35.48 gallons.

The equation W=1.8d+17.48 can be used to find the average number of gallons of bottled water consumed each year by a consumer.

In this equation, W represents the average number of gallons of bottled water consumed, and d represents the number of years since 2000.

To find the average number of gallons of bottled water consumed in a specific year, you can plug in the value of d into the equation and solve for W.

For example, if you want to find the average number of gallons of bottled water consumed in the year 2010, you would plug in the value of d=10 (since 2010 is 10 years after 2000) into the equation:

W=1.8(10)+17.48

W=18+17.48

W=35.48

So, the average number of gallons of bottled water consumed in the year 2010 is 35.48 gallons.

Similarly, you can plug in different values of d into the equation to find the average number of gallons of bottled water consumed in different years.

Let the difference of the sample means be y1 -y2 t- (Round to three decimal places as needed.) Calculate the P-value P-value- (Round to four decimal places as needed.)

Answers

a) The null and alternative hypotheses are:
H0: µ1 = µ2
Ha: µ1 ≠ µ2

b) The test statistic is:
t = 0.117

c) The P-value is:
P-value = 0.9072

To test the null hypothesis at α= 0.05 using the pooled t-test, we need to follow these steps:

Step 1: Choose the null and alternative hypotheses. The null hypothesis is that the mean page views per visit for website 1 are equal to the mean page views per visit for website 2. The alternative hypothesis is that the mean page views per visit for website 1 are not equal to the mean page views per visit for website 2.

H0: µ1 = µ2
Ha: µ1 ≠ µ2

Step 2: Calculate the test statistic. The test statistic for the pooled t-test is given by:

t = (y1 - y2) / (sp * √(1/n1 + 1/n2))

where sp is the pooled standard deviation, given by:

sp = √(((n1 - 1) * s1^2 + (n2 - 1) * s2^2) / (n1 + n2 - 2))

sp = √(((70 - 1) * 4.9^2 + (90 - 1) * 5.4^2) / (70 + 90 - 2)) = 5.178

t = (7.5 - 7.4) / (5.178 * √(1/70 + 1/90)) = 0.117

Step 3: Calculate the P-value. The P-value is the probability of observing a test statistic as extreme or more extreme than the one we calculated, assuming the null hypothesis is true. We can use a t-distribution table or a calculator to find the P-value. The degrees of freedom for the pooled t-test are n1 + n2 - 2 = 70 + 90 - 2 = 158.

Using a t-distribution table or a calculator, we find that the P-value is 0.9072.

Step 4: Since the P-value is greater than the significance level of 0.05, we fail to reject the null hypothesis. There is not enough evidence to suggest that the mean page views per visit for website 1 are different from the mean page views per visit for website 2.

Thus:

a) The null and alternative hypotheses are:
H0: µ1 = µ2
Ha: µ1 ≠ µ2

For a certain 2-year polytechnic school, studies by the registry show that the probability of a randomly selected first-year student returning for a second year is 0.54. Assume that 8 first-year students are randomly selected.
Create a probability distribution showing the possible outcomes and corresponding probabilities.
Compute and interpret P(X≤3).
Compute the expected number from many trials of randomly selected groups of 8 freshmen that return for the second year.
Compute the standard deviation.
The Student Services Department randomly selected 8 freshmen and met with them for two one-on-one advising sessions during the freshmen year. Of the 8 students who participated, 7 returned for the second year. Can you consider the advising program a success?

Answers

The probability distribution for the possible outcomes can be created using the binomial distribution formula:
P(X=x) = (n choose x) * p^x * (1-p)^(n-x)
Where n is the number of trials (in this case, 8), x is the number of successes (returning for a second year), p is the probability of success (0.54), and 1-p is the probability of failure.

The probability distribution is as follows:
| X | P(X) |
|---|------|
| 0 | 0.010 |
| 1 | 0.059 |
| 2 | 0.167 |
| 3 | 0.282 |
| 4 | 0.313 |
| 5 | 0.223 |
| 6 | 0.106 |
| 7 | 0.033 |
| 8 | 0.005 |
To compute P(X≤3), we add the probabilities for X=0, X=1, X=2, and X=3:
P(X≤3) = 0.010 + 0.059 + 0.167 + 0.282 = 0.518
This means that there is a 51.8% chance that 3 or fewer of the randomly selected first-year students will return for a second year.
The expected number of students returning for a second year can be calculated using the formula:
E(X) = n * p = 8 * 0.54 = 4.32
This means that on average, 4.32 of the randomly selected first-year students will return for a second year.

The standard deviation can be calculated using the formula:
σ = √(n * p * (1-p)) = √(8 * 0.54 * 0.46) = 1.39

Finally, to determine if the advising program was a success, we can compare the observed number of students returning (7) to the expected number (4.32). Since 7 is greater than 4.32, it appears that the advising program may have had a positive effect on the students' decision to return for a second year. However, further analysis would be needed to determine if this difference is statistically significant.

Answers

The notation f(x) means:
- the value of the function at the number x
- f of x

These two options are the correct ones. The notation f(x) typically refers to a mathematical function named "f" that takes an input value "x" and returns an output value. The function f maps the input value x to a unique output value f(x). The symbol "f" is often used to represent a generic function, and the variable inside the parentheses, "x", represents the argument or input value of the function.

For example, if we have the function f(x) = x + 2, then f(3) = 3 + 2 = 5. This means that when we input the number 3 into the function, the output is 5.

Answers

The answer of -x+3y=20; 7y=x will be x = -[tex]\frac{7}{2\\}[/tex] and y = - [tex]\frac{1}{2}[/tex].

Given,

-x+3y=20 .... (1)

7y=x .... (2)

By using the method of substitution.

We will use equation (2) as

7y=x

=>y= [tex]\frac{x}{7}[/tex] ....(3)

Putting equation (3) in (1)

We have, -x+3([tex]\frac{x}{7}[/tex])=20

Taking L.CM.

[tex]\frac{-7x+3x}{7}[/tex] = 20

-7x +3x = 140

-4x = 140

0r, x = - [tex]\frac{140}{4}[/tex]

x = - [tex]\frac{7}{2}[/tex]

Now by putting value of x in equation (2),  we get

7y = x

7y = -[tex]\frac{7}{2}[/tex]

0r, y = -[tex]\frac{1}{2}[/tex]

Thus, x = -[tex]\frac{7}{2\\}[/tex] and y = - [tex]\frac{1}{2}[/tex]

P(X = x) 0.05 0.20 3k 0.15 k
(a)Find the value of k.
(b) E(X),
(c) Var (X), (d) Var (2 – 5X).

Answers

(a) To find the value of k, we need to use the fact that the sum of the probabilities of all possible outcomes is equal to 1. In this case, we have:
0.05 + 0.20 + 3k + 0.15 + k = 1
Solving for k, we get:
4k = 1 - 0.05 - 0.20 - 0.15
4k = 0.60
k = 0.15
Therefore, the value of k is 0.15.

(b) To find E(X), we need to multiply each value of x by its corresponding probability and sum the results. In this case, we have:
E(X) = (-1)(0.05) + (0)(0.20) + (1)(3k) + (2)(0.15) + (3)(k)
E(X) = -0.05 + 0 + 0.45 + 3k
E(X) = 0.40 + 3k
Substituting the value of k that we found in part (a), we get:
E(X) = 0.40 + 3(0.15)
E(X) = 0.85
Therefore, the expected value of X is 0.85.

(c) To find Var(X), we need to use the formula Var(X) = E(X^2) - (E(X))^2. First, we need to find E(X^2):
E(X^2) = (-1)^2(0.05) + (0)^2(0.20) + (1)^2(3k) + (2)^2(0.15) + (3)^2(k)
E(X^2) = 0.05 + 0 + 3k + 0.60 + 9k
E(X^2) = 0.65 + 12k
Substituting the value of k that we found in part (a), we get:
E(X^2) = 0.65 + 12(0.15)
E(X^2) = 2.45
Now, we can find Var(X):
Var(X) = E(X^2) - (E(X))^2
Var(X) = 2.45 - (0.85)^2
Var(X) = 2.45 - 0.7225
Var(X) = 1.7275
Therefore, the variance of X is 1.7275.

(d) To find Var(2 - 5X), we need to use the formula Var(a + bX) = b^2Var(X), where a = 2 and b = -5. Substituting the values and the variance of X that we found in part (c), we get:
Var(2 - 5X) = (-5)^2Var(X)
Var(2 - 5X) = 25(1.7275)
Var(2 - 5X) = 43.1875
Therefore, the variance of 2 - 5X is 43.1875.

An oil tank is being drained. the volume, V, in litres, of oil remaining in the tank after t minutes can be modeled by the function
V(t) = 0,5 (10 – t)^3
where 0 ≤ t ≤ 10.
a) how much oil is in the tank initially?
b) determine the average rate of change of volume in the first 1 minutes.
c) estimate the instantaneous rate of change of volume at 5 minutes. Do NOT use Calculus.

Answers

a) Initially, when t = 0, the volume of oil in the tank is given by:

V(0) = 0.5(10 - 0)^3

V(0) = 0.5(1000)

V(0) = 500

So, initially there are 500 litres of oil in the tank.

b) The average rate of change of volume in the first 1 minute is given by:

ΔV/Δt = (V(1) - V(0))/(1 - 0)

ΔV/Δt = (0.5(10 - 1)^3 - 500)/1

ΔV/Δt = (0.5(729) - 500)/1

ΔV/Δt = -285.5

So, the average rate of change of volume in the first 1 minute is -285.5 litres/minute.

c) To estimate the instantaneous rate of change of volume at 5 minutes, we can use the average rate of change over a small interval around 5 minutes. For example, we can use the average rate of change from 4.9 minutes to 5.1 minutes:

ΔV/Δt = (V(5.1) - V(4.9))/(5.1 - 4.9)

ΔV/Δt = (0.5(10 - 5.1)^3 - 0.5(10 - 4.9)^3)/0.2

ΔV/Δt = (-61.4455 - (-62.985))/0.2

ΔV/Δt = 7.6975

So, the estimated instantaneous rate of change of volume at 5 minutes is 7.6975 litres/minute.

Answers

Renee's monthly payment will be $504.46. The closest answer choice is d. $504.46.

How did we arrive at this value?

To calculate Renee's monthly payment, we need to first determine the total cost of the new car after taxes and fees and subtract the trade-in value of her old car. Then, we can use the loan information to calculate the monthly payment.

Total cost of the new car:

List price: $19,675

Vehicle registration fees: $1,420

Documentation fees: $85

Sales tax: 8.92% of ($19,675 + $1,420 + $85) = $1,894.51

Total cost = $19,675 + $1,420 + $85 + $1,894.51 = $22,074.51

Trade-in value of the old car:

2002 Buick LeSabre in good condition: $3,374 (from the table)

85% of trade-in value: 0.85 x $3,374 = $2,867.90

Net cost of the new car:

$22,074.51 - $2,867.90 = $19,206.61

To calculate the monthly payment, we can use the formula for the present value of an annuity:

PV = PMT x (1 - (1 + r)^(-n)) / r

where PV is the present value of the loan, PMT is the monthly payment, r is the monthly interest rate (11.34%/12), and n is the number of payments (4 years x 12 months/year = 48).

Solving for PMT:

PMT = PV x r / (1 - (1 + r)^(-n))

PMT = $19,206.61 x 0.1134/12 / (1 - (1 + 0.1134/12)^(-48))

PMT = $504.46

Therefore, Renee's monthly payment will be $504.46. The closest answer choice is d. $504.46.

Where a is the slope and b is the y-intercept, these two values are constants, and the variables are x and y.

First, notice that the line intercepts the y-axis at the point (0, 0), then b = 0.

So we can write:

y = a*x

A baseball is hit so that its height, s, in feet after t seconds is S= = - 16t² +60t+2. For what time period is the ball at least 46 ft above the ground?​

Answers

A baseball is hit so that its height, s, in feet after t seconds is S= - 16t² +60t+2. Based on the inequality, the ball is at least 46 feet above the ground in [0.20, 1.55] seconds.

How do we find this value?

To find the period of time the ball is at least 46 feet above the ground, we first need to solve the given inequality, which will be:

S= -16t²+60t+2[tex]\geq[/tex]46

Simplifying, we find the following value:

S= -16t²+60t- 44[tex]\geq[/tex] 0

Dividing both sides by -4, we find:

S= 4t²-15t+11[tex]\leq[/tex] 0

So, to solve this inequality, we can use the quadratic formula:

t= (-b± sqrt(b²-4ac))/2awhere, a=4, b= -15 and c=11.

Plugging these values into the formula, we get:

t= [15± sqrt ((-15)² -4(4)(11))]/2x4

Simplifying this expression, we get:

t= [15± sqrt(97)]/8

Therefore, it follows that the ball is at least 46 feet above the ground during the time period:

[(15- sqrt(97))/8, (15+sqrt(97))/8]

So, rounded to two decimal places, this is approximately:

[0.20, 1.55] seconds.

the zeros and their multiplicities. Consider f(x)=2x^(5)+11x^(4)-2x^(3)-74x^(2)-60x+48

Answers

The zeros and their multiplicities of the function f(x)=2x^(5)+11x^(4)-2x^(3)-74x^(2)-60x+48 are:

x = -4, multiplicity 1

x = (-5 + √(41))/(2), multiplicity 1

x = (-5 - √(41))/(2), multiplicity 1

The zeros of a function f(x) are the values of x that make f(x) equal to 0. The multiplicity of a zero is the number of times that zero appears as a solution. To find the zeros and their multiplicities of the given function f(x)=2x^(5)+11x^(4)-2x^(3)-74x^(2)-60x+48, we can use synthetic division or factoring.

First, let's use synthetic division to find one of the zeros:

2x^(5)+11x^(4)-2x^(3)-74x^(2)-60x+48 = 0

Using synthetic division, we can find that x = -4 is a zero of the function:

(-4) | 2  11  -2  -74  -60  48
    | 0  -8  20   88  104 -176
    ---------------------------
      2   3  18   14   44 -128

Now we can divide the original function by (x+4) to find the remaining zeros:

f(x) = (x+4)(2x^(4)-x^(3)+14x^(2)+10x-32)

Using the quadratic formula, we can find the remaining zeros of the function:

x = (-b ± √(b^(2)-4ac))/(2a)

x = (-(10) ± √((10)^(2)-4(2)(-32)))/(2(2))

x = (-10 ± √(164))/(4)

x = (-10 ± √(4*41))/(4)

x = (-10 ± 2√(41))/(4)

x = (-5 ± √(41))/(2)

So the zeros of the function are x = -4, x = (-5 + √(41))/(2), and x = (-5 - √(41))/(2).

The multiplicity of each zero is 1, since each zero appears only once as a solution.

Therefore, the zeros and their multiplicities of the function f(x)=2x^(5)+11x^(4)-2x^(3)-74x^(2)-60x+48 are:

x = -4, multiplicity 1

x = (-5 + √(41))/(2), multiplicity 1

x = (-5 - √(41))/(2), multiplicity 1
