Jacob 2

Jacob took five summative tests in Mathematics during the first quarter, each with a maximum score of 100. Jacob's five integer test scores have a mean of 85, a median of 87, and a mode of 92. What is Jacob's lowest possible score from one of his five tests?

Correct answer:

x =  68

Step-by-step explanation:

μ=85 Q2=87 m=92 n=5  x; y; 87; 92; 92; x<y<87  (x+y+87+92+92)/n = μ x+y+87+92+92 = n μ x+y+87+92+92=5 85=425 x+y=154  y=Q21=871=86 x=154y=15486=68
