answer:

the mean for this is 27

step-by-step explanation:

all you have to do is add up all of the times

15, 18, 20, 22, 28, 37, 49

which would have given you

189

then you divide that number by how much times were written down

7 would be that number so

189/7 = 27

and this is what it is written in one equation

(15+18+20+22+28+37+49)/7

hope this helps you! :)

Multiply: (v2x^3 + V12x) (2_10x^5 + V6x^2)

Effectus [21]

Step-by-step explanation:

STEP

Equation at the end of step 1

((22•3x2) - 10x) + 5 = 0

STEP

Trying to factor by splitting the middle term

2.1 Factoring 12x2-10x+5

The first term is, 12x2 its coefficient is 12 .

The middle term is, -10x its coefficient is -10 .

The last term, "the constant", is +5

Step-1 : Multiply the coefficient of the first term by the constant 12 • 5 = 60

Step-2 : Find two factors of 60 whose sum equals the coefficient of the middle term, which is -10 .
