Answer:
134.6
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula. This is X when Z has a p-value of 1-0.01 = 0.99. So it is X when Z = 2.325.
The level is L = 134.6
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation, large sample size can be approximated to a normal distribution with a mean and standard deviation
50 x 18 not that hard actually :) 900
Answer:
56,000 = 5.6 x 10^**4
Step-by-step explanation:
56,000 = 56 x 10,000
Inserting decimal:
56 x 1,000 = 5.6 x 10,000
Answer:
56,000 = 5.6 x 10^**4
( btw ^** means exponent )
Answer:
738 square ft
Step-by-step explanation:
Area of the composite figure
= 21*(12 + 9 + 6) + 9*(9 + 6) + 6*6
= 21*27 + 9*15 + 6*6
= 567 + 135 + 36
= 738 square ft
Answer:
8
Step-by-step explanation:
A=πr^2
64π=πr^2
since answer is in terms of pi, ignore the pi.
sqrt(64)=8
