Please answer question below.

Let's assume that the width of the rectangular poster is "x".

According to the problem, the length is 8 more inches than half the width, which can be expressed as:

length = (1/2)x + 8

The area of the poster is given as 40 square inches, so we can write the equation:

Area = length × width

Substituting the values of length and width in terms of "x", we get:

40 = ((1/2)x + 8) × x

Simplifying the equation:

40 = (x^2)/2 + 8x

Multiplying both sides by 2 to eliminate the fraction:

80 = x^2 + 16x

Rearranging the equation in standard quadratic form:

x^2 + 16x - 80 = 0

Using the quadratic formula:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 1, b = 16, and c = -80

x = (-16 ± sqrt(16^2 - 4(1)(-80))) / 2(1)

x = (-16 ± sqrt(736)) / 2

x = (-16 ± 8sqrt(9)) / 2

We can discard the negative solution since width cannot be negative:

x = (-16 + 24) / 2

x = 4

So, the width of the poster is 4 inches.

Using the equation for length:

length = (1/2)x + 8

length = (1/2)(4) + 8

length = 2 + 8

length = 10

Therefore, the dimensions of the poster are 10 inches by 4 inches.

An irrational number is a number that cannot be expressed as a simple fraction. Therefore 0.6263646 is irrational.

Let us assume that the variables:

d = distance

t = time (in seconds)

~

The question assumes that the horse will move 15 meters every second. Therefore:

d = 15t

IF:

t (time) = 1 seconds, then:

d = 15(1)

d = 15

IF:

t (time) = 2 seconds, then:

d = 15(2)

d = 30

IF:

t (time) = 5 seconds, then:

d = 15(5)

d = 75

The fraction of the production run that was defective is 2/25.

What is the fraction?

A fraction is a numerical quantity that represents a part of a whole or a ratio between two quantities. It is expressed as one integer divided by another integer, with a horizontal line separating the two numbers. The number above the line is called the numerator and the number below the line is called the denominator.

The fraction of a production run that was defective is 0.08. This can be written as a fraction with a numerator of 0.08 and a denominator of 1:

0.08/1

To express this fraction with a denominator other than 1, we can multiply both the numerator and denominator by the same number, without changing the value of the fraction. For example, we can multiply by 100 to get:

(0.08/1) * (100/100) = 8/100

Simplifying this fraction gives:

8/100 = 2/25

Therefore, the fraction of the production run that was defective is 2/25.

We need to add 6 mL of the 14% solution to the 8 mL of the 7% solution to obtain a 10% medication solution.

An equation is a mathematical statement that indicates that two expressions are equal. It consists of two sides separated by an equal sign (=). The expressions on both sides of the equal sign can contain numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division. Equations are used to describe relationships between different variables, to solve problems, and to make predictions.

Let's call the number of milliliters of the 14% solution we need to add "x".

First, let's figure out how much medication is in the 8 mL of the 7% solution. Since the solution is 7%, we know that 7% of the solution is medication. We can convert that to milliliters by multiplying by the total volume of the solution:

0.07 x 8 mL = 0.56 mL of medication in the 7% solution

Next, let's figure out how much medication we want in the final solution. We want a 10% solution, so we want 10% of the total volume to be medication. We can write that as:

0.10 (x + 8 mL) = 0.1x + 0.8 mL

Now we can set up an equation based on the amount of medication in the 14% solution we add and the amount of medication in the final solution:

0.14x + 0.56 mL = 0.1x + 0.8 mL

Simplifying the equation, we get:

0.04x = 0.24 mL

Dividing both sides by 0.04, we get:

x = 6 mL

Using binomial probability and cumulative distribution function, the probability of having 24 heads is 0.000022

This problem can be solved using the binomial distribution. Let X be the number of heads that occur in 27 tosses of the fair coin. Then X follows a binomial distribution with parameters n = 27 and p = 0.5.

We want to find the probability that at most 24 heads occur, which is equivalent to finding the probability that X is less than or equal to 24. We can use the cumulative distribution function (CDF) of the binomial distribution to calculate this probability:

[tex]P(X \leq 24) = \sum_{k=0}^{24} {27 \choose k} (0.5)^{27}[/tex]

We can use a calculator or software to evaluate this sum, or we can use the complement rule to find the probability of the complement event (i.e., 25 or more heads) and subtract from 1:

[tex]P(X \leq 24) = 1 - P(X \geq 25) = 1 - \sum_{k=25}^{27} {27 \choose k} (0.5)^{27}[/tex]

Using a calculator or software, we find that the probability is approximately 0.000022, which corresponds to answer choice (a).

I believe the expression you provided is:

(log(x) + 4x^3) / x

To find the discontinuities of this expression, we need to identify any values of x that would cause the expression to be undefined. These values are called the discontinuities.

There are two types of discontinuities to look for:

Removable discontinuities: These occur when a function is undefined at a certain point but can be made continuous by redefining the function at that point.

Non-removable discontinuities: These occur when a function is undefined at a certain point and cannot be made continuous by redefining the function at that point.

To find the discontinuities of the given expression, we need to look for values of x that would make the denominator equal to zero, as this would result in a non-removable discontinuity.

So we solve the equation:

x = 0

This means that x cannot be equal to zero, as it would make the denominator zero and the expression undefined.

Therefore, the only discontinuity of the expression is at x = 0.

Note that there are no removable discontinuities in this expression, as the expression is continuous everywhere except at x = 0.

To find the fraction of members between 150 and 160 cm tall, we need to look at the portion of the frequency polygon that corresponds to this height range.

First, we can calculate the total frequency of members between 150 and 160 cm by adding up the frequencies for the "150 < x ≤ 160" class and the "160 < x ≤ 170" class, which gives:

Total frequency = 5 + 0 = 5

Next, we can calculate the total frequency of all members by adding up all the frequencies, which gives:

Total frequency = 10 + 5 + 0 + 1 = 16

Therefore, the fraction of members between 150 and 160 cm tall is:

Fraction = Total frequency between 150 and 160 cm / Total frequency of all members

= 5 / 16

= 0.3125

So, approximately 31.25% of the members were between 150 and 160 cm tall.

The fraction of members between 150-160cm is found by dividing the frequency of the 150-160cm height segment by the total number of club members.

In order to find out the fraction of members who were between 150 and 160 cm tall, we first need to focus on the corresponding frequency value for the height segment - 150< x ≤160 in the table. This value gives us the count of people who stand within these heights. Simultaneously, we need the total number of club members, which can be derived by adding all the frequency values together.

Once we have these two values, the fraction of members is calculated by dividing the frequency of the 150-160 height segment by the total frequency (number of club members).

Please note that this fraction will be a 'raw' one, and you may need to simplify it to its smallest terms to make it more understandable.

After answering the provided question, we can conclude that Therefore, circle the length of the minor arc AB is approximately 50.9 cm.

A circle appears to be an a double component that is defined as the collection of all points in a jet that are equidistant out from hub. A circle is typically depicted with a capital "O" for the centre and a bottom end "r" for the radius, which represents the distance from where it started to any point on the circle. The formula 2r gives the girth (the distance from the center of the circle), where (pi) seems to be a proportionality steady roughly equal to 3.14159. The formula r2 computes the circumference of a circle, which is the quantity of space inside the circle. To calculate the length of the minor arc AB, we need to first find the central angle that it subtends.

C = 2πr

r = C/(2π)

r = 65/(2π) ≈ 10.34 cm

angle = (arc length / radius) x (180/π)

ADB = 360° - AOB

ADB = 360° - 72° = 288°

angle ADB = (arc length AB / 10.34) x (180/π) = 288°

arc length AB = (288° x 10.34 cm x π) / 180 ≈ 50.9 cm

Therefore, the length of the minor arc AB is approximately 50.9 cm.

(i) The domain of f(x) is all real numbers, since there are no restrictions on the input variable x.

(ii) We have:

f(x) = x^4 - 2x^3

f'(x) = 4x^3 - 6x^2

f''(x) = 12x^2 - 12x

(iii) To find the critical points, we need to solve the equation f'(x) = 0:

4x^3 - 6x^2 = 0

2x^2(2x - 3) = 0

x = 0 or x = 3/2

So the critical points are (0,0) and (3/2, -27/16).

(iv) To determine where f(x) is increasing or decreasing, we need to examine the sign of f'(x) on different intervals. We can make a sign chart for f'(x):

| x | -∞ | 0 | 3/2 | +∞ |

|---------|--------|-------|-------|--------|

| f'(x) | - | 0 | + | + |

From the sign chart, we see that f(x) is decreasing on the interval (-∞, 0) and increasing on the interval (0, 3/2) and (3/2, +∞).

(v) To find the relative extrema, we need to examine the sign of f'(x) around the critical points. We can make a table:

|---------|-------|-------|-------|-------|

| f'(x) | - | + | - | + |

| f(x) | 0 | 0 | -27/16| -27/16|

From this table, we see that f(x) has a relative minimum of -27/16 at x = 3/2, and no relative maximum or minimum at x = 0.

(vi) To find the intervals where f(x) is concave up or concave down, we need to examine the sign of f''(x) on different intervals.

We can make a sign chart for f''(x):

| x | -∞ | 0 | 1 | +∞ |

|---------|--------|-------|------|--------|

| f''(x) | + | - | + | + |

From the sign chart, we see that f(x) is concave down on the interval (-∞, 0) and concave up on the intervals (0, 3/2) and (3/2, +∞).

(vii) To find the points of inflection, we need to solve the equation f''(x) = 0:

12x^2 - 12x = 0

12x(x - 1) = 0

x = 0 or x = 1

So the points of inflection are (0,0) and (1, -1).

(viii) To sketch the graph of f(x), we can use the information we have gathered so far.

At x = 0, f(x) has a relative minimum of 0 and is concave down. At x = 3/2, f(x) has a relative minimum of -27/16 and is concave up. The point (1, -1) is a point of inflection.

The values of Mean = 6.3 and Median = 6

A dot plot is a type of data visualization that displays data points as dots on a number line. Each dot represents a single data point and is placed at the corresponding value on the number line.

Here, each dot corresponds to a particular value in the data set, below diagram.

Mean: The mean is calculated by dividing the total value of all the data sets by the total number of data sets.

You can figure out the total as follows:

0 (1) = 0            4 (3) = 12             5(8) = 40          6(3) = 18

7(1) = 7              8(5) = 40             9(2) = 18           10 (3) = 30

Sum = 0+12+40+18+7+40+18+30 = 165

Number of data set = 26

⇒Mean = 165/26

             = 6.346 ≈ 6.3               (nearest tenth place)

⇒Median: The center value in the data collection is known as the median. Since there are 26 data points total, the middle value is located between data points 13 and 14. The median value will be determined by averaging the 13th and 14th data points.

So, the 13th and 14th values both are 6.

We have a survey of 53 randomly selected homeowners. So,

Sample size, n = 53

Mean spend of home maintenance, μ

= $66 per month

Standard deviations, σ = $ 11 per month

We have to determine the Lower and Upper end point or bound of confidence interval. First we calculate the Z score for 98% of confidence interval. The level of significance, α = 0.02 and α/2 = 0.01, so using distribution table [tex]z_{ \frac{\alpha}{2}} = 2.326[/tex]

Now, Margin of error , [tex]MOE = z_{\frac{\alpha}{2}} ( \frac{\sigma }{\sqrt{}n}) [/tex]

[tex] = 2.326 ( \frac{11}{ \sqrt{}53 })[/tex]

=> E = 3.51

At 98% confidence interval estimate of the population mean is, [tex]\bar x - E < \mu < \bar x + E[/tex]

[tex]66 - 3.51 < \mu < 66 + 3.51[/tex]

=> 62.49 < μ < 69.51

Therefore, Lower end point or bound

= 62.49 and Upper end point or bound

= 69.51.

Answer: 4 cans of tuna

Step-by-step explanation:

5 1/2 x 4 = 22

Answer:

To find which tuna is a better deal, divide the cost by the number of ounces of tuna you are getting to get the cost per ounce.

$0.90/5  = $0.18 per ounce

$2.40/12 = $0.20 per ounce

Since the 5-ounce can of tuna has a cheaper unit rate price, meaning you are getting a better value, makes this the best option. I hope this was helpful and have a great day! :)

Step-by-step explanation:

[tex]\tan(68^o )=\cfrac{\stackrel{opposite}{AC}}{\underset{adjacent}{7}}\implies 7\tan(68^o)=AC\implies 17.3\approx AC[/tex]

Make sure your calculator is in Degree mode, as opposed to Gradians or Radians mode.

Quick Clarification:

if your put in your calculator tan(68) in Radians mode, your calculator assumes you meant 68 radians, if in Gradians mode, your calculator assumes you meant 68 Gradians, now, if you have it on Degree mode, your calculator thinks you meant tan(68°).

All trigonometric calculations depend on the mode used, since a circle can be divided in many ways and thus different modes mean, different angles, 68 Radians are extremely different than 68°.

Answer:

9 x 17 is greater than 9 x 15

Step-by-step explanation:

You can tell without finding the product because 17 is greater than 15, and the higher the number you multiply by, the larger the solution will be. I hope this helped :)

Using calculus, we can find the functions of the inverse functions as follows:

a. f(x) = x/5.

b. f(x) = ∛ 2x

c. f(x) = x - 10

d. f(x) = 2x/3 - 17

One of the most crucial areas of mathematics that addresses ongoing change is known as calculus. Calculus is primarily built on the two ideas of derivatives and integrals. A function's integral measures the area under its curve, whereas a function's derivative measures its rate of change.

Whereas the integral adds together a function's discrete values over a range of values, the derivative explains the function at a particular point.

Here in the question,

The inverse of the functions is:

f(x) = x/5.

f(x) = ∛ 2x

f(x) = x - 10

f(x) = 2x/3 - 17
