Answer:

6.3°

Step-by-step explanation:

$\because \: \pi^{c} = 180 \degree \\ \\ \therefore \: 1^{c} = \frac{180 \degree }{\pi} \\ \\ \therefore \: 0.11^{c} = \frac{180 \degree }{3.14} \times 0.11 \\ \\ \therefore \: 0.11^{c} = \frac{180 \degree }{314} \times 11 \\ \\ \therefore \: 0.11^{c} = \frac{1980 \degree }{314} \times 11 \\ \\ \therefore \: 0.11^{c} = 6.30573248\degree \\ \\ \huge \red{ \boxed{\therefore \: 0.11^{c} = 6.3\degree }} \\ \\$

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

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.

Answer:

x = 38 degrees.

The angle marked 2x-1 =75 degrees

Step-by-step explanation:

the opposite angles of a parallelogram are equal.

so:

2x -1 = 75

2x = 76

x = 38
