Answer:
16 ÷ 5 = 3.2 gallons
Step-by-step explanation:
Answer:
It is B
Step-by-step explanation:
Since it's a sample size, we use x, as the mean and s= standard deviation
_
Given: x =27, s = 2 and total sample = 32.
Probability that a recruit is at least 31 years old?
Let's calculate the Z score :
_
X - x 31 - 27
Z = ----------- → Z = -------- → Z = 2 (now look up in the Z score table,
s 2
Area (Z=2) =0.9772 , but Z ≥ 2 (at least) , then :
Area (Z≥2) = Area (Z≤ - 2) = 0.0228
P(≥31)= 0.0228
Answer:
-112x-168y, 6(6a-1).
Step-by-step explanation:
-14(8x+12y)
-112x-168y
--------------
36a-6
6(6a-1)
Answer:
56 + 8x
Step-by-step explanation:
8(7) + 8(x)
= 56 + 8x
