Answer:
13 1/3 pounds.
Step-by-step explanation:
3 feet = 36 inches
3 feet 4 inches = 36 + 4 = 40 inches
By proportion the weight of the larger bar = 12 * 40/36
= 12 * 10/9
= 120/9
= 13 1/3 pounds.
1. - 4^3 = -1 * 4*4*4 = - 64
2. (-4)^3 = (-4)(-4)(-4) = - 64
3. 4^3 = 4 * 4 * 4 = 64
Answer:
16cm
Step-by-step explanation:
Area is A = bh
to find a base, b = A/h
A=80
h=5
so then we have b = 80/5 = 16
Answer:
0.588
Step-by-step explanation:
By law of large number, the probability of the mean of 30 boards sample would be the same as 1 sample being between 94.8 in and 95.8 in within a normal distribution with mean 95 and standard deviation of 0.52. We can calculate this probability by subtracting the cumulative probability of 94.8 from the cumulative probability of 95.8 in.
P(94.8<x<95.8) = P(x < 95.8) - P(x < 94.8) = 0.938 - 0.35 = 0.588
