Answer:
a. of the central limit theorem.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, a large sample size, larger than 30, can be approximated to a normal distribution with mean
and standard deviation 
In this problem, the sample size is 100, so it is sufficiently large to use the Central Limit Theorem. The mean of the sample in 69 and the standard deviation of the sample is 0.58.
So the correct answer is:
a. of the central limit theorem.
Answer:
answer is 2
Step-by-step explanation:
Answer:
7 - 51
Step-by-step explanation:
additive inverse : a number that when added to a given number gives zero the additive inverse of 4 is −4
First change the fraction to decimals or common denominators.
3/4 = 0.75 and 1/5 = 0.2
0.75 + 0.2 = 0.95 = 95/100 = 19/20
(3/4) = (15/20)
(1/5) = (4/20)
(15/20) + (4/20) = 19/20
Because the triangles are congruent,
all their corresponding sides are equal,
so 2x-9=x+5, x=14
first side : x+5=14+5=19
second side: 15
third side: 8
P = 19+8+15= 42 Answer is D
