In circle Y, what is m? 82° 100° 106° 118°

Rashid [163]

we know that

The measure of the interior angle is the semi-sum of the arcs comprising it and its opposite

In this problem

$94\°=\frac{1}{2}[arc\ SR+arc\ TU]$

we have

$arc\ SR=106\°$

Solve for measure of the arc TU

$188\°=[arc\ SR+arc\ TU]$

$arc\ TU=188\°-106\°$

$arc\ TU=82\°$

therefore

the answer is

the measure of the arc TU is $82\°$

Answer:

$21 each

Step-by-step explanation:

Since she had $72 left that means that she spent $168 so then you divide that by the 8 identical statues.

$240 - $72 = $168

$168/8 = $21

The proportion of junior executives leaving large manufacturing companies within three years is to be estimated within 3 percent

Leona [35]

Answer: 709

Step-by-step explanation:

The formulas we use to find the required sample size :-

1. $n=(\dfrac{z^*\cdot \sigma}{E})^2$

, where $\sigma$ = population standard deviation,

E = Margin of error .

z* = Critical value

2. $n=p(1-p)(\dfrac{z^*}{E})^2$ , where p= prior estimate of population proportion.

3. If prior estimate of population proportion is unavailable , then we take p= 0.5 and the formula becomes

$n=0.25(\dfrac{z^*}{E})^2$

Given : Margin of error : E= 3% =0.03

Critical value for 95% confidence interval = z*= 1.96

A study conducted several years ago revealed that the percent of junior executives leaving within three years was 21%.

i.e. p=0.21

Then by formula 2., the required sample size will be :

$n=0.21(1-0.21)(\dfrac{1.96}{0.03})^2$

$n=0.21(0.79)(65.3333)^2$

$n=(0.1659)(4268.44008889)\\\\ n=708.134933333\approx709$ [Round to the next integer.]

Hence, the required sample size of junior executives should be studied = 709
