A number equals itself
Addition Property=For all real number X,y & Z,. if
X=Y then X+y=y+Z
Subtraction Property=For all real number X,Y And Z if X=y then X-Z=y-Z.

Based on the given information, let x represent the grade for the fifth quiz.
(79+88+95+71+x)/5=85
(333+x)/5=85
333+x=425
x=92
Jackson would have to earn a 92 on his fifth quiz to earn an average of 85.
Answer:
75,62.5
Step-by-step explanation:
Given that Mr. Dennis gave his class a 20-question multiple choice quiz. The distribution of raw scores had a mean of 15 and a standard deviation of 2.5
If X is the correct questions in the 20 mcq then
X is with mean = 15 and std dev = 2.5
when score is multiplied by 5
random variable now is
Y = 5x
E(Y) = Mean of Y = 

Thus new score out of 100 would have mean = 75 and std deviation = 62.5
