The length is 3m. You do the area(45) divided by the width(15) to hey the length, which is 3.
Answer:
.13.5%
Step-by-step explanation:
The probability that a student will receive a grade between 74 and 76 is calculated as follows:
µ+2σ=70+2(2)=70+4=74
µ+3σ=70+3(2)=70+6=76
From the above empirical rule it can be observed that 13.5% of observations fall in between 1 and 2 standard deviations above the mean.
Therefore, the probability that a student will receive a grade between 74 and 76 is 13.5%.
Thus, the correct options is A.13.5%.
I would say your answer is option C.

Answer:
(d) 192π = π(5)²h
Step-by-step explanation:
A useful first step is to put the given values into the given formula. That is illustrated in choice D.
V = πr²h
192π = π(5)²h
