His bones weigh 16 pounds. The way you solve this is by first making 1/5 a decimal 1/5=0.2. Then you just have to do 80*0.2=16  Hope this helps!

Solve the equation 1/4a=3
Tanzania [10]

Answer:

a= 12

Step-by-step explanation:

(1/4)*a = 3 // - 3

(1/4)*a-3 = 0

1/4*a-3 = 0 // + 3

1/4*a = 3 // : 1/4

a = 3/1/4

a = 12

In a random sample of 62 professional actors, it was found that 40 were extroverts. Please find the point estimate, 95% confiden
den301095 [7]

The point Estimate is 0.645 , the confidence interval is (0.525 ,0.764).

<h3>What is Point Estimate ?</h3>

The point estimate is the proportion of success in the sample.

From the data given

p = 40/62

p = 0.645

The point Estimate is 0.645

(b) Confidence interval for true proportion is

\rm {p -Z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}  , p +Z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}

For 95 % Z = 1.96

p =0.645

1-p = 0.355

putting the values

\rm {0.645 -1.96 \sqrt{\dfrac{0.645\times0.355}{62}}  , {0.645 +1.96 \sqrt{\dfrac{0.645\times0.355}{62}} \\

(0.525 , 0.764)

Lower Limit = 0.525

Upper Limit = 0.764
