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.
Answer:
4 + 1 + 20 + 100 = 1000
5 + 20 + 100 = 1000
25 + 100 = 1000
125 = 1000
The equation would be false because 125 does not equal 1000

Step-by-step explanation:
Answer:
Well I don't know the choices but if there is a 7 in the hundreds place like 1,700 then it is correct.
Step-by-step explanation:
This is the answer because 70 times 10 equals 700.
