Answer:

The most appropriate inference procedure for the investigation is;

a. A linear regression t-interval for the slope

Step-by-step explanation:

Given that the slope of an horizontal line is zero, we have that there is no change in the y (dependent) variable when there is a change in the x-variable, therefore, it is important to find the true relationship between the two variables, 'x', and 'y'

The confidence interval of the slope is calculated and analyzed to determine if it excludes or includes, 0, such that, if the confidence interval exclude 0, then, it is unlikely that the slope is 0, therefore, there the relationship between the variables, 'x', and 'y' is significant

Therefore, a linear regression t-interval for the slope is most appropriate.

The area of the rectangle will be given as Area = 2W² + W. Then the correct option is A.

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.

The length of a rectangle is 1 more than twice the width.

The area of the rectangle is given by the formula A = L x W.

Then the area of the rectangle will be

The relation between the length and width is given below.

L = 2W + 1

Then the area will be

Area = L x W

Area = (2W + 1)W

Area = 2W² + W

Step-by-step explanation:

First 60$ - 35$=25$

1h=5$

2h=10$

3h=15$

4h=20$

5h=25$

So you can pay 35$ for the snow play ski park and then you can be there 5hours.So 35$ for the entry+25$ for the 5 hours=60$

Step-by-step explanation:

Answer:

y = 3/5x + -9

or y = 3/5x - 9

Step-by-step explanation:

Since you are already given the slope for this equation all you have to do is plug in the ordered pair in this equation: y = mx+b

Here is what this equation stands for:

y = the y in the order pair you are given, in this case it would be -6

m = This is the slope, sometimes you may not be given the slope so you would have to find it, but in this case, you are given it, the slope is 3/5

x = the x in the ordered pair you are given, in this case it would be 5

b = This is the y-intercept, you will mostly be solving for this most of the time

(5,-6)

(x, y)

y = mx+b (Use this Formula)

-6 = 3/5(5) +b (The numbers have been substituted within the formula)

-6 = 3+b (simplify the equation by multiplying the slope by the x)

-6-3 = b ( once simplified the left side of the equation, go to the right side, but remember when you do that you have to change the sign because you are eliminating 3 on the left side completely, "what you do on one side, do it to the other side")

-9 = b (solve)

y = 3/5x + -9 (plug in the slope and B(y-intercept) within the formula - y = mx+b, make sure that you are not plugging in x and y for this step)

Answer:

a) [tex]y(t) = 30 + 25t[/tex]

b) The pollution level at 4 o'clock in the afternoon​ is of 280 parts per million.

Step-by-step explanation:

The pollution level in the center of a city at 6 am is 30 parts per million and it grows in linear fashion by 25 parts per million every hour.

This means that the pollution in t hours after 6 am is given by:

[tex]y(t) = 30 + 25t[/tex], which is the answer to question a.

b. The pollution level at 4 o'clock in the afternoon​

4 in the afternoon is 10 hours after 6 am, so this is y(10).

[tex]y(10) = 30 + 25*10 = 30 + 250 = 280[/tex]

The pollution level at 4 o'clock in the afternoon​ is of 280 parts per million.

Answer:

49 units

Step-by-step explanation:

The units on the other 3 sides (this is excluding the slanted portion ofc.)

would add up to 36.

Now you only left with doing the slanted portion of the shape. We must use pythagorean theorem to solve for the slanted portion. The longer leg, 12 units long. Just count from the point (18,4) and then stop at (18,16) it stops on the same line as the point (13,16)

Leg B=12

Leg A=5

Leg C=?

[tex]a^2+b^2=c^2[/tex]

25+144=196

Then square root  169. You will get 13

36+13=49

Step-by-step explanation:

The wide of the path is 28 + 2x

The area is the sum of the areas of all its faces.

The area of a solid object is a measure of the total area that the surface of the object covers.

area of the pool = 8 * 28 meteres²

total area of pool and path = 800 meteres ²

The width of the path is = 800 - 224

                                    = 576 meters ²

Answer:

Student B

Step-by-step explanation:

Soil percolation is the porosity of soil to the downward flow of water through it. A soil with high percolation allows water to drain through it downwards in a less period of time.

From the given experiment by students, it takes 25 min for water to percolate through the soil sample of student A, 10 min for the soil sample of student B and 40 min for the soil sample of student C. Thus, the student that had the soil sample with highest percolation rate is B.

Answer:

0.0384 < 0.05, which means that we can conclude that the mean amount of time that college students spend in the shower is significantly different from 5 minutes.

Step-by-step explanation:

A facilities manager at a university reads in a research report that the mean amount of time spent in the shower by an adult is 5 minutes.

This means that the null hypothesis is [tex]H_{0} = 5[/tex]

He decides to collect data to see if the mean amount of time that college students spend in the shower is significantly different from 5 minutes.

This means that the alternate hypothesis is [tex]H_{a} \neq 5[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

Null hypothesis:

Tests [tex]H_{0} = 5[/tex], which means that [tex]\mu = 5[/tex]

In a sample of 8 students, he found the average time was 5.55 minutes and the standard deviation was 0.75 minutes.

This means, respectively, that [tex]n = 8, \mu = 5.55, \sigma = 0.75[/tex]

Test statistic:

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{5.55 - 5}{\frac{0.75}{\sqrt{8}}}[/tex]

[tex]z = 2.07[/tex]

Pvalue:

Since we are testing if the mean is different from a value, and z is positive. The pvalue is two multiplied by 1 subtracted by the pvalue of z = 2.07.

z = 2.07 has a pvalue of 0.9808

2*(1 - 0.9808) = 2*(0.0192) = 0.0384

Decision:

0.0384 < 0.05, which means that we can conclude that the mean amount of time that college students spend in the shower is significantly different from 5 minutes.
