On Friday, Marvin sold 4 suits that had a mean sale

price of $125. On Saturday, he sold 6 suits that had

a mean sale price of $140. What was the mean sale

price, to the nearest dollar, for all 10 of the suits he

sold on Friday and Saturday?

A. $130

B. $132

C. $133

D. $134

C.$133

Step-by-step explanation:

You have to add all numbers then divide by how many numbers there are.

So, in this case, you must add 125 and 140 to get 265

Then you must divide by 2 since there are 2 numbers

265/2 = 132.5

Round to the nearest dollar

The final answer is $133

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
