klemol [59]
A number divided by 7 is 9: \frac{x}{7} =9
Multiply both sides by 7 to get the answer so it'll be: \frac{x}{7} (7)=9(7)

An insurance company estimates 45 percent of its claims have errors. The insurance company wants to estimate with 99 percent con
nydimaria [60]

Answer:

We need a sample size of at least 657.

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}.

The margin of error is given by:

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

45 percent of its claims have errors.

So \pi = 0.45

99% confidence level

So \alpha = 0.01, z is the value of Z that has a pvalue of 1 - \frac{0.01}{2} = 0.995, so Z = 2.575.

What sample size is needed if they wish to be within 5 percent of the actual

This is a sample size of at least n, in which n is found when M = 0.05.

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

0.05 = 2.575\sqrt{\frac{0.45*0.55}{n}}

0.05\sqrt{n} = 1.28

\sqrt{n} = \frac{1.28}{0.05}

\sqrt{n} = 25.62

\sqrt{n}^{2} = (25.62)^{2}

n = 656.4

We need a sample size of at least 657.

Anyone Can help me? Thanks
Elena L [17]

Answer:

9.8

Step-by-step explanation:

<em>updated</em>

9^2=x^2+4^2

9*9=x*x+4*4

81=x*x-16

+16. +16

97=x*x

√97=√x*x

√97=x

So the answer is √97, but the question wants it rounded so it's actually 9.8
