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:
B
Step-by-step explanation:
M(x, y) = ((x1 + x2)/2, (y1 + y2)/2) = ((-2 + 6)/2, (5 - 9)/2) = (4/2, -4/2) = (2, -2)
Answer:
<
Step-by-step explanation:
5/5 is bigger than 1/5.
Answer:
subtract 2y
Step-by-step explanation:
x= 5-2y or x= -2y+5
