2/4 times 85 plus 25 radius 89
Answer:
C
Step-by-step explanation:
The answer is C because 1 * 2 = 2, 2 * 2 = 4, and 4 * 2 = 8.

ok done. Thank to me :>
a. First we solve the finite population correction factor
σx from the formula:
σx = [s / sqrt(n)] * sqrt [(N – n) / (N – 1)]
σx = [0.40 / sqrt(16)] * sqrt[(500 – 16) / (500 – 1)]
σx = 0.0985
Then we compute for z score when x ≥ 3 minutes:
z = (x – m) / σx
z = (3 – 3.10) / 0.0985
z = -1.015
From the tables, the probability (p value) using right
tailed test is:
P = 0.845 = 84.5%
b. At P = 0.85, the z score is z = 1.04
1.04 = (x – 3.10) / 0.0985
x = 3.20
Hence there is a 85% chance it will be below 3.20 minutes
