Answer:
d. 90 cm, 1.2 cm
Step-by-step explanation:
Given that:
The sample size n = 36
For the length of the link:
The mean 
= 2.5
The standard deviation s = 0.2 cm
In a chosen 36 links, The mean and standard deviation for the length chain is as follows:
Mean = n
Mean = 36×2.5
Mean = 90 cm
The Standard deviation = s×√n
The Standard deviation = 0.2×√36
The Standard deviation = 0.2×6
The Standard deviation = 1.2 cm
Answer:
move every dot to the left by two units and flip the whole thing over the y axis
Step-by-step explanation:
Yes you can why because you can
A group consists of five men and seven women. six people are selected to attend a conference.
a. in how many ways can six people be selected from this group of twelve?
(12 over 6) = 924
b. in how many ways can six women be selected from the seven women?
(7 over 6) = 7
c. find the probability that the selected group will consist of all women.
7 / 924 = 1/132 = 0.007576
