Since the total number of marbles is 40, that is our size of the sample. there are 16 red ones on that sample, so the probability of extracting a red marble from the box is given by the ratio of successes divided the total number of marbles:

p = 15/40

Carmen simplifies the expression (4 y 8 x 6) 25 (4 x 6 y 7). The coefficient of the variable y in her simplified answer is 4. 6.

Sever21 [200]

Carmen simplifies the expression and gets the coefficient of y is 10. Thus, the correct option is C.

<h3>What is simplification?</h3>

Simplification is to make something easier to do or understand and to make something less complicated.

Given

Carmen simplifies the expression $\rm (4 y + 8 x + 6) + 25 + (4 x +6 y +7)$ .

We can add x term with x, y term with y, and constant with constant.

On simplifying, we have

$\rm (4 y + 8 x + 6) + 25 + (4 x +6 y +7)\\\\12x + 10y + 38$

Thus, the coefficeint of y is 10.
