Answer:

a. Independent

b. Matched

c. Independent

Step-by-step explanation:

If the sample is chosen randomly and there is no biasness in the selection of sample from the population then the selected sample is independent. The matched pairs are when the selection process involves a relation with the sample selected with the desired test results.

We can conclude that:

a. the population is independent.

b. the population is matched.

c. the population is independent.

If a researcher selects a sample from an entire population under study in a random and unbiased manner, the sample population is aid to be independent.

If the selection process in drawing the sample involves a relation with what is expected from the test results, then they are is matched pairs.

Thus, we can conclude that:

a. the population is independent.

b. the population is matched.

c. the population is independent.

Answer:

31.42 m

Step-by-step explanation:

Since, the path is circular :

The distance traveled can be I tin by taking the Circumference of the path :

Circumference, C = πd

d = diameter = 20 meters

C = π * 20

Since penguin swam. Only halfway around the island.

Hence, distance traveled = 1/2 * C

= 1/2 * 20π

= 31.42 m

Answer:

Step-by-step explanation:

Upon factoring all terms we are left with the product of

[(x-4)(x+6)(x-6)]/[5(x-6)(3x+5)(x-4)]

The (x-4)s and (x-6)s cancel out and we are left with

(x+6)/(5(3x+5)) which is also equal to

(x+6)/(15x+25)

Answer:

The equation is not correct because the statement indicates that they charged $150 to clean one house which means that the equation showed that the earnings were the result of multiplying the price to clean one house for the number of houses cleaned, which is:

e=150h

As the statement indicates that they plan to raise their fees and they will charge $175 to clean each house, this means that the price changes from 150 to 175 and you have to replace this in the formula and because of this the new equation would be:

e=175h

The equation the owners wrote is not right because it shows that the earnings are equal to a fixed charge of $150 plus a price of $25 for the number of houses and the statement says that the price is $175 for each house so the number of houses cleaned should be multiplied for that price.

Answer:

$121.05

Step-by-step explanation:

Since we are told that there is 9 members and each once is 13.45 we can simply do 13.45 times 9 to get the number 121.05.

  inverse

  y = 10/x

Step-by-step explanation:

Inverse variation is described by an equation of the form ...

  y = k/x

The value of k is a constant equal to ...

  k = xy = 5·2 = 10·1 = 15·2/3 = 20·1/2 = 10

__

Here, the products of the x- and y-values are all 10, so the inverse variation equation is ...

  y = 10/x

Hi there!

[tex]\large\boxed{2 m/s^{2}}[/tex]

Use the equation F = m · a where:

F = Force (N)

m = mass (kg)

a = acceleration (m/s²)

Plug in the given values:

12 = 6a

Divide both sides by 6:

12/6 = a

a = 2 m/s²

Answer:

Skewed right

Step-by-step explanation:

Most of the data is to the right, so it's not skewed left.

Uniform is mostly even, so not that either.

Bell shape is centered and vaguely triangular, so incorrect, hence the only remaining option is skewed right.

Hope this helps :)

Answer:

The confidence limits for the proportion that plan to vote for the Democratic incumbent are 0.725 and 0.775.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

Of the 500 surveyed, 350 said they were going to vote for the Democratic incumbent.

This means that [tex]n = 500, \pi = \frac{350}{500} = 0.75[/tex]

80% confidence level

So [tex]\alpha = 0.2[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.2}{2} = 0.9[/tex], so [tex]Z = 1.28[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.75 - 1.28\sqrt{\frac{0.75*0.25}{500}} = 0.725[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.75 + 1.28\sqrt{\frac{0.75*0.25}{500}} = 0.775[/tex]

The confidence limits for the proportion that plan to vote for the Democratic incumbent are 0.725 and 0.775.

Answer:

7*6*5*4*3 = 7P5 = 2520

Step-by-step explanation:

There will be 56 points in the sample space when two batteries are selected without replacement from the bag.

To determine the number of points in the sample space when selecting two batteries without replacement, we can use the counting principle.

The counting principle states that if there are m ways to do one task and n ways to do another task, then there are m * n ways to do both tasks together.

In this case, the first battery can be selected in 8 ways (since there are 8 batteries in the bag).

After selecting the first battery, there are 7 remaining batteries in the bag. For the second battery, there are 7 ways to select it (one less than the previous selection).

Therefore, the number of points in the sample space is given by multiplying the number of possibilities for the first selection (8) by the number of possibilities for the second selection (7):

8 * 7 = 56

There will be 56 points in the sample space when two batteries are selected without replacement from the bag.

Answer:

  C. 7 1/4 units

Step-by-step explanation:

It can be useful to plot the points on a graph.

The two points are on the same horizontal line, so the distance between them is the difference of their x-coordinates.

  4 3/4 -(-2 2/4) = (6 +2) +(3/4 +2/4) = 6 5/4 = 7 1/4 . . . . units

Answer:

24 square yards

Step-by-step explanation:

Find the diagram attached.

The area of the diagram = Area of rectangle + Area of triangle

Area of rectangle = 3 * 4

Area of rectangle = 12 square yards

Area of triangle = 1/2 * base * height

Area of triangle = 1/2 * 6 * 4

Area of triangle = 12 square yards

Area of the diagram = 12 + 12

Area of diagram =  24 square yards

Hence 24 square yards of carpeting is needed
