Answer:
1/2 and 4/12
Step-by-step explanation:
2/6=(2:2)/(6:2)=1/3
2/6=(2*2)/(6*2)=4/12
Answer:
Surface Area - 122
Step-by-step explanation:
Plan A: 30 + 0.01m
Plan B: 20 + 0.05m
in order for 2 plans cost the same, both need to be equal
so should be
20 + 0.05m = 30 + 0.01m
answer is D. last one
20 + 0.05m = 30 + 0.01m
Answer:
The values of a and b are -1.28 and 1.28 respectively.
Step-by-step explanation:
It is provided that the area of the standard normal distribution between a and b is 80%.
Also it is provided that a < b.
Let us suppose that a = -z and b = z.
Then the probability statement is
Simplify the probability statement as follows:
Use the standard normal distribution table to determine the value of <em>z</em>.
Then the value of <em>z</em> for probability 0.90 is 1.28.
Thus, the value of a and b are:
Thus, .
