The number of peanuts in bags is normally distributed with a mean of 184.7 peanuts
and a standard deviation of 3.3 peanuts.
what is the z-score of a bag containing 178 peanuts?

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".

d.) yes, because the volume of the cone is greater than the volume of the sphere

step-by-step explanation:

y/x of point b= y/x of point a
