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

A bag contains eight batteries, all of which are the same size and are equally likely to be selected. Each battery is a different brand. If you select two batteries at random, use the counting principle to determine how many points will be in the sample space if the batteries are selected without replacement.

Answers

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.

The penguin exhibit at a zoo has a raised circular island that is surrounded by water. The diameter of the island is 20 \text{ meters}20 meters20, start text, space, m, e, t, e, r, s, end text. One penguin swims half way around the island before hopping out.
How far did the penguin swim?
Give your answer in terms of pi.

Answers

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



A cleaning company's monthly earnings depend on the

number of houses cleaned, h. Spotless Homes charges

$150 each month to clean one house.

The owners of Spotless Homes plan to raise their fees

starting next month. They will charge $175 each month to

clean each house. The owners write this new equation to

represent the new earnings, e, for cleaning h houses:

e = 150 + 25h

Is their equation correct? Why or Why not? Explain your

reasoning

Answers

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.

How many square yards of carpeting is needed to cover the entire gym?

O 18 square yards

O 24 square yards

O 36 square yards

44 square yards

Answers

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

Answer:

  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 ...

What acceleration will result when a 12 N force is applied to a 6 kg object?
If you know please include the equation, it would really help me out, thanks so much!

Answers

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

There are 9,481 eligible voters in a precinct. 500 were selected at random and asked to indicate whether they planned to vote for the Democratic incumbent or the Republican challenger. Of the 500 surveyed, 350 said they were going to vote for the Democratic incumbent. Using an 80% confidence level, what are the confidence limits for the proportion that plan to vote for the Democratic incumbent

Answers

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.

For the following studies in which tests comparing two means are conducted, select whether the populations are independent or matched pairs:

a. A study is conducted to see what effect a new drug has on dexterity. A random sample of 30 people is chosen. They are given a series of tasks to perform and a score reflecting their performance. A dose of the drug is administered to the 30 people, and they are then given a similar series of tasks to perform and scored again.
b. A study is conducted to determine the difference between the average amount that people spend on durables and non-durables when they go shopping. A sample of people is chosen and their shopping purchases are observed.
c. A study is conducted to determine if there is a difference between the average length of time spent in traffic on the way to work and the average length of time spent in traffic going home from work for people in a city. A random sample of workers is chosen and asked how long they spend getting to work. Another separate random sample of workers is chosen and asked how long they spend getting home from work.

Answers

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.

What are Independent and Matched Populations?

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.
