6/100 • 30 = 1.8
1.8 + 30 = 31.8
Answer is $31.8
The answer is D to the next step
The ratio would be 4:6 because there are 6 number in total and 4 of them are odd numbers.
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.
Your answer would be 64. There are two sides on a coin. 2^6 would be 64.
Hope this helps.
