Answer:
Step-by-step explanation:
Formula to find radius:
<em>hope this helps......</em>
Mean, x_bar = 1518
Standard deviation, sigma = 325
Range required: 1550 ≤ X ≤ 1575
Z = (X - x_bar)/sigma
Z1 = (1550-1518)/325 ≈ 0.1
Z2 = (1575-1518)/325 ≈ 0.18
From Z tables,
P(Z1) = 0.5398
P(Z2) = 0.5714
P(1550≤X≤1575) = P(Z2) - P(Z1) = 0.5714 - 0.5398 = 0.0316
The correct answer is C.
4n - 3 = 4 * 10 - 3 = 40 - 3 = 37
....
Answer: 5 days
Step-by-step explanation:
so we need to find:
55 - 6a = 40 - 3a
with a being the days we need to find
-40 on each side
15 - 6a = -3a
+6a on each side
15 = 3a
divide each side by 3
5 = a
