Answer:
1 : 3 : 9
Step-by-step explanation:
For every Pant = 3 shirts
If
Pant = x ; shirt = 3x
For :
Every 9 shirts = 27 pairs of shoes
Simplifying further :
1 shirt = 3 pairs of shoes
3 shirts = 3 * 3 = 9 pairs of shoes
Expressing as ratio:
1 Pant = 3 shirts = 9 pairs of shoes
1 : 3 : 9
Answer:
-r
Step-by-step explanation:
How many kittens are there?
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:
