When you calculate the sample size for a proportion, you use an estimate for the population proportion; namely . A conservative
LuckyWell [14K]

Answer: A. 0.50

Step-by-step explanation:

The formula to find the sample size : n=p(1-p)(\dfrac{ z^*}{E})

, where p= Prior estimate of population proportion.

E= Margin of error

z* =Critical z-value.

When , we do not have prior estimate of population proportion , we use p= 0.5 because at p=0.5 it gives the maximum same sample size for the corresponding confidence interval and margin of error.

Therefore , the conservative value for n can be obtained by using p=0.50.

Therefore , the correct answer is A.0.50 .

Find the length of the radius of a sphere with a surface area of 5541.77 cm2.
ladessa [460]
The area of a sphere: A  = 4.π.R²

A= 5541.77 → 5541.77 = 4.π.R²

R² = (5541.77)/(4.π)
R² = 441; → R =√441; R = 21 cm

Find the scale factor of the dilation. Then tell whether it is enlargement or reduction.​
mariarad [96]

Answer:

  a) 1/2; reduction

  b) 5/4; enlargement

Step-by-step explanation:

In each case, the scale factor is CP'/CP. When it is more than 1, the dilation is an enlargement.

Even before you run the numbers, you can tell if it is an enlargement or not. If the dilated figure is larger, P is closer to C than is P'. If P' is closer to C, then it is a reduction.

a) CP'/CP = (4-2)/4 = 2/4 = 1/2 . . . . a reduction

__

b) CP'/CP = 25/20 = 5/4 . . . . an enlargement
