(2y)(2y)(2y)(2y). 2y to the fourth power is the same as saying 2y 4 times or 2y times 4
Answer:
4(2x - 3).
Step-by-step explanation:
(x * 2 - 3) * 4
= 4(2x - 3)
Net worth day 2 day not really. look in wallet. month 2 month check saving/checking account. net worth isn't done on either normally.
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:
D. The input force is equal to the output force
Step-by-step explanation:
A pulley changes the direction of the applied force, but does not change its magnitude. The mechanical advantage is the ratio of output force to input force, so must be 1 when the force magnitude does not change.
