Kendrick's math quiz grades are 90, 100, 48, 88, 100, and 96. find the mean of kendrick's scores. a) 48 b) 52 c) 87 d) 93

C) 87

Step-by-step explanation:

Mean (or average) is calculated by finding the sum of all the values and then dividing by the number of values. In this case it would be (90+100+48+88+100+96)/6 = 87

Hope this helps!

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

answer4 to the second power is 16

and 4 to the third power is 64,
