Answer:
58.5 pounds each.
Step-by-step explanation:
If two bookcases weigh 117 pounds and each weighs the same amount, each bookcase must weigh half of the total weight. 117/2 equals 58.5.
They weigh 58.5 pounds each.
You just have to dived the total amount by the amount of thing. So you would didvid 117 by 2 which equals 58.5 pounds.
2 + x + 2x = 14
3x + 2 = 14 (combine like terms)
3x = 12 (subtract 2 from both sides)
Hence the answer is 3x = 12. (B)
Frank
f(x)= 9,974.73 (1.05)x
test statistic is 0.176
Given Data
p>33
a=0.05
n=50
x=33.3
d(population deviation)=12
Test statistics=?
Solution
Test statistic z=(p-x)\(d/sqrt(50))
z=(33.3-30)\(12\sqrt(50))
z=0.176
