Answer:

Step-by-step explanation:

You want the value of the piecewise function for various values of x.

The first step in evaluating a piecewise function is determining which domain is applicable to the value of x you have. Then you use the corresponding function, evaluating it in the usual way.

For x = -5, the applicable domain is x < -3, so the function is ...

  h(-5) = -4(-5) -18 = 20 -18

  h(-5) = 2

For x = 0, the applicable domain is -3 ≤ x < 1, so the function is ...

  h(0) = 1

For x = 1 or 4, the applicable domain is x ≥ 1, so the function is ...

  h(1) = 1 +2 = 3

  h(4) = 4 +2 = 6

The standard deviation is 15.76. The typical reading rate for the data set varies from the mean by an average of 15.76 words per minute.

The dataset is given as:

Reading Rate

(words per minute) Frequency

60 6

65 8

70 12

75 5

80 1

85 1

90 2

95 5

100 20

Calculate the mean using

Mean = Sum/Count

So, we have

Mean = (60 * 6 + 65 * 8 + 70 * 12 + 75 * 5 +  80 * 1 +  85 * 1 +  90 * 2 +  95 * 5 + 100 * 20)/(6 + 8 + 12 + 5 + 1 + 1 + 2 + 5 + 20)

Evaluate

Mean = 81.92

The standard deviation is

\(\sigma = \sqrt{\frac{\sum f(x - \bar x)^2}{\sum f -1}}\)

So, we have:

SD = √[6 * (60 - 81.92)^2 + 8 * (65 - 81.92)^2 + 12 * (70 - 81.92)^2 + 5 * (75 - 81.92)^2 + 1 * (80 - 81.92)^2 +  1 * (85 - 81.92)^2 +  2 * (90  - 81.92)^2 + 5 * (95 - 81.92)^2 + 20 * (100 - 81.92)^2)]/[(6 + 8 + 12 + 5 + 1 + 1 + 2 + 5 + 20 - 1)]

This gives

SD = √248.382779661

Evaluate

SD = 15.76

Hence. the standard deviation is 15.76. The typical reading rate for the data set varies from the mean by an average of 15.76 words per minute.

Answer:

Step-by-step explanation:

1) Number of Jeans = x

Number of blouses  = y

total items = 6

x + y = 6 ---------------------(I)

Cost of 'x' Jeans = 300 * x = 300x

Cost of 'y' blouses = 100 * y = 100y

300x + 100y = 1000 -------------------(II)

Equations:

x  + y = 6

300x + 100y = 1000

2)              Multiply equation (I) by (-100) and so y will be eliminated. Then, we could find the value of 'x'

(I)* (-100)              -100x - 100y = -600

(II)                          300x + 100y = 1000           {Now, add}

                             200x            = 400

x = 400/200

x = 2

Plug in x = 2 in equation(I)

 2 + y = 6

       y = 6 - 2

y = 4

Number of Jeans = 2

Number of blouses  = 4

3) The equation has one solution. so, they are consistent and independent.

The relationship between the number of minutes and the number of gallons of water in the pool can be represented by the following table:

Minutes (x) Gallons of Water (y)

0                               0

11                               1

22                               2

33                               3

44                               4

To determine the relationship between the number of minutes and the number of gallons of water in the pool, we can observe that the pump fills the pool at a constant rate. In the given information, it states that at the end of 11 minutes, 1 gallon of water has been filled. This means that the rate at which the pump is filling the pool is 1 gallon per 11 minutes.

Based on this information, we can create a table to represent the relationship. We start with 0 minutes and 0 gallons of water since no time has passed and the pool is empty. For every 11-minute interval, we add 1 gallon to the previous amount of water filled. Hence, after 11 minutes, 1 gallon is filled, after 22 minutes, 2 gallons are filled, and so on.

The resulting table represents the relationship between the number of minutes (x) and the number of gallons of water (y) in the pool, showing that the number of gallons increases by 1 for every 11-minute interval.

Answer:  Angle a = 47.7 degrees, b = 81.0 degrees, and c = 54.3 degrees

Step-by-step explanation: Since this triangle represents an SSS case(meaning that all sides of the triangle are given), we can use the law of cosines equation and plug the values in for all the sides to get the angles, thus solving the triangle. The equation is below.

\(cos A = b^2+c^2-a^2/2bc\)

Once I found angle A by solving and using arccos function, I used the law of sines,

\(sin a/A = sin b/B = sin c/C\)

and got the angles for the other sides.

When a range of values is used to estimate a population parameter, it is called an interval estimate. The correct answer is option D.

An interval estimation is the evaluation of a parameter of a population by computing an interval, or range of values, within which the parameter is most likely to be located. An interval estimate gives you a range of values where the parameter is expected to lie. In other words, an interval estimate is a range in which the population parameter probably falls for a given level of confidence. We have to establish a level of confidence because we can never be 100 percent sure that the population mean falls within our confidence interval. A confidence interval is the most common type of interval estimate.

To achieve a volume uncertainty of ±3575 mm³, the required inner radius uncertainty for the ping pong balls with a nominal inner radius of 39.6 mm is approximately ±0.107 mm.

To calculate the required inner radius uncertainty, we need to determine the range of inner radius values that would result in a volume uncertainty of ±3575 mm³. Given the formula V = (3/4)π(ro^3 - ri^3), where ro is the outer radius and ri is the inner radius, we can substitute the given values:

V = (3/4)π(40^3 - 39.6^3)

Now, we want to find the inner radius uncertainty that would yield a volume uncertainty of ±3575 mm³. Let's assume the inner radius uncertainty is ±x mm. This means the minimum and maximum inner radii would be (ri - x) mm and (ri + x) mm, respectively.

Substituting the minimum and maximum inner radius values into the volume formula, we have:

Minimum volume = (3/4)π(40^3 - (39.6 - x)^3)

Maximum volume = (3/4)π(40^3 - (39.6 + x)^3)

We want the difference between the minimum and maximum volumes to be equal to ±3575 mm³. Thus:

(3/4)π(40^3 - (39.6 + x)^3) - (3/4)π(40^3 - (39.6 - x)^3) = ±3575

Simplifying the equation, we find:

(3/4)π[(39.6 + x)^3 - (39.6 - x)^3] = ±3575

Solving for x, we obtain x ≈ 0.107 mm, which represents the required inner radius uncertainty to achieve a volume uncertainty of ±3575 mm³.

The point estimate of the corresponding to the population proportion is 977 college graduates

What is population proportion?

The percentage of the population that possesses a particular trait is known as the population proportion. Say there are 1,000 people in the population and 237 of them have blue eyes, for instance. The percentage of people with blue eyes is 237/1000, or 237/1000. You would write this fact as follows: p = 237/1000 since the population proportion is denoted by the letter p.

The percentage college students graduates is 69%

The number of college students studying = 1415

Point estimate is the process of calculating a single value from a sample of data.

In a sample with 'x' number of successes and 'n' samples, the point estimate of a population proportion, p', is as follows:

p' = x/n

∴ x= p'n

\(x = 1415 * \frac{69}{100}\)

  = 14.15*69

  = 976.35 ≈ 977

A threshold effect is when a small change in one variable results in a noticeable change in another variable. In this example, a small 8% increase in salt content of the chips is enough to produce a noticeable change in the saltiness of the chips to the sample of consumers.

The snack manufacturer can calculate the increase in salt content of their chips needed to produce the threshold effect by first determining the baseline salt content of the chips. Once this is known, they can then calculate what percentage increase to the salt content is needed by multiplying the baseline salt content by 8%. For example, if the baseline salt content of the chips is 10%, then the 8% increase in salt content would be calculated as 10% x 8% = 0.8%. This means that the snack manufacturer needs to increase the salt content of their chips by 0.8% to reach the threshold effect desired by the sample of consumers.
