Answer:
0.97725
Step-by-step explanation:
Given that Professor Heinz has given the same multiple-choice final exam in his Principles of Microeconomics class for many years. After examining his records from the past 10 years, he finds that the scores have a mean of 76 and a standard deviation of 12.
i.e.
Std error of mean = sigma/sqrt n = 2
Thus the sample mean is N(76,2)
Required probability = probability that a class of 36 students will have an average greater than 72 on Professor Heinz's final exam.

Answer:
A
Step-by-step explanation:
Answer:
A - x = (k-c)/5
Step-by-step explanation:
To solve this problem, we would solve for x like we would in 2x = 6 :
5x + c = k
5x = k-c (subtract c from both sides)
x = k/5 - c/5 (divide 5 on both sides)
x = (k-c)/5 (simplify)

Answer:
It holds approximately 4 litres in accent
Step-by-step explanation:
In terms, 1 litre = 1000 cubic centimetres.
-----------------------------------------
Therefore, to find How many liters of oil the container hold. Divide 4000 cubic centimeters by 1000.
⟼ 4000 ÷ 1000
⟼ 4
Therefore, 4000 cubic centimeters volume of oil holds 4L of oil
