Allushta [10]

Answer:

y =mx + c

7 = 5/2 (-2) + c

7 = - 5 + c

c = 7 + 5

c = 12

Therefore, y = 5/2x + 12

Multiply through by 2

2y = 5x + 24

You're welcome

Answer: Second Option

m=0.09

Step-by-step explanation:

The formula for calculating the average rate of change between two values of x (x_1 and x_2) is:

m=\frac{f(x_2)-f(x_1)}{x_2-x_1}

f (x_1) and f (x_2) are the values of the function when x = x_1 and x = x_2

In this case

x_1=3\\x_2=6

Observe that when x=3, f(x) =2.41 and when x=6, f(x)=2.68

Finally the average rate of change from 3 to 6 storms is:

m=\frac{2.68-2.41}{6-3}

m=0.09

A quality-conscious disk manufacturer wishes to know the fraction of disks his company makes which are defective. Step 2 of 2: S
Anna35 [415]

Answer:

The 98% confidence interval for the population proportion of disks which are defective is (0.082, 0.118).

Step-by-step explanation:

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

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

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

Suppose a sample of 1536 floppy disks is drawn. Of these disks, 1383 were not defective.

1536 - 1383 = 153

This means that n = 1536, \pi = \frac{153}{1536} = 0.1

98% confidence level

So \alpha = 0.02, z is the value of Z that has a pvalue of 1 - \frac{0.02}{2} = 0.99, so Z = 2.327.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.1 - 2.327\sqrt{\frac{0.1*0.9}{1536}} = 0.082

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.1 + 2.327\sqrt{\frac{0.1*0.9}{1536}} = 0.118

The 98% confidence interval for the population proportion of disks which are defective is (0.082, 0.118).
