Answer:

I think its 86

Step-by-step explanation:

As the two lines going in the same direction are parallel and angles within parallel lines add to 180.

so 180-94=86

94 and angle 5 are supplementary angles so
94 + angle 5 = 180
angle 5 = 180 -94
angle 5 = 86
Hope this helps

1. The sample mean weight of 100 chimpanzees was measured to be 82.4 pounds, with a standard deviation of 12.6 pounds. Using a 1

tia_tia [17]

Using the t-distribution, as we have the standard deviation for the sample, we could claim that the mean weight in pounds is in the interval (79.1, 85.7).

<h3>What is a t-distribution confidence interval?</h3>

The confidence interval is:

$\overline{x} \pm t\frac{s}{\sqrt{n}}$

In which:

$\overline{x}$ is the sample mean.

t is the critical value.

n is the sample size.

s is the standard deviation for the sample.

The critical value, using a t-distribution calculator, for a two-tailed <em>99% confidence interval</em>, with 100 - 1 = <em>99 df</em>, is t = 2.6259.

The other parameters have values given by:

$\overline{x} = 82.4, s = 12.6, n = 100$ .

We could claim that the mean is any value in the 99% confidence interval, which has bounds given by:

$\overline{x} - t\frac{s}{\sqrt{n}} = 82.4 - 2.6259\frac{12.6}{\sqrt{100}} = 79.1$

$\overline{x} - t\frac{s}{\sqrt{n}} = 82.4 + 2.6259\frac{12.6}{\sqrt{100}} = 85.7$

$\frac{21}{36}\\\\21=\fbox3\times7\\\\36=\fbox3\times3\times2\times2\\\\therefore\\\\\frac{21}{36}=\frac{21:\fbox3}{36:\fbox3}=\boxed{\boxed{\frac{7}{12}}}$
