erma4kov [3.2K]

Answer:

30 people

Step-by-step explanation:

100 people to the survey. And the question is practically asking how many people are left. So we have to subtract 60 from 100. And then subtract 10.

1.) 100 - 60 = 40

2.) 40 - 10 = 30

Hope this helps you out! : )

Suppose you are the manager of Speedy Oil Change which claims that it will change the oil in​ customers’ cars in less than 30 mi
Veronika [31]

Answer:

Explained below.

Step-by-step explanation:

(1)

The hypothesis can be defined as follows:

<em>H</em>₀: The Speedy Oil Change will change the oil in​ customers’ cars in more than 30 minutes on average, i.e. <em>μ</em> > 30.

<em>H</em>ₐ: The Speedy Oil Change will change the oil in​ customers’ cars in less than 30 minutes on average, i.e. <em>μ</em> ≤ 30.

(2)

Use Excel to compute the sample mean and standard deviation as follows:

\bar x=\text{AVERAGE(array)}=24.917\\\\s=\text{STDEV.S(array)}=8.683

Compute the test statistic as follows:

t=\frac{\bar x-\mu}{s/\sqrt{n}}=\frac{24.917-30}{8.683/\sqrt{36}}=-3.51

The degrees of freedom is:

df = n - 1

   = 36 - 1

   = 35

Compute the p-value as follows:

p-value=P(t_{35}

(3)

The <em>p</em>-value = 0.0006 is very small.

The null hypothesis will be rejected at any of the commonly used significance level.

(4)

There is sufficient evidence to support the claim that the Speedy Oil Change will change the oil in​ customers’ cars in less than 30 minutes on average.

20 points<br> How on Earth am I supposed to do this
goblinko [34]

Answer: -89

Step-by-step explanation:

So your equation is

- 9(a) - 7(x) - 9(c) - 9(b) - 7(y)

You know that (a) (b) and (c) = -1

You also know that (x) and (y) = 7

So, when you put this into the equation, it will look like this:

- 9(-1) - 7(7) - 9(-1) - 9(-1) - 7(7)

When you work that out you will get left with your answer, which is -89.

HOPE THIS HELPS!!!
