Answer:
1 1/3
Step-by-step explanation:
Something that is not a inproper fraction is a proper fraction which is :
The numerator is less than the denominator
Examples: 1/3, 3/4, 2/7.
Or a mixed fraction which is:
A whole number and proper fraction together
Examples: 1 1/3, 2 1/4, 16 2/5
Let x = our unknown number
10x = 600
Divide by 10 on both sides to isolate the variable x.
x = 600/10
x = 60
600 is 10 times as much as 60.
Answer: a) 0.8413, b) 0.9987.
Step-by-step explanation:
Since we have given that
Mean = 3 pounds
Standard deviation = 0.25 pounds
n = 28 bricks
So, (a) What is the probability that all the bricks in the sample exceed 2.75 pounds?

b) What is the probability that the heaviest brick in the sample exceeds 3.75 pounds?

Hence, a) 0.8413, b) 0.9987.
I am going to say it is probably ....B....
