Marcia performs an experiment in which she pulls a marble from a bag. In her
experiment, she finds that she is twice as likely to pull a red marble as a blue
marble. If Marcia pulls 10 red marbles, how many blue marbles does she pull?

She pulls 5 blue marbles

Step-by-step explanation:

Let x be the number of blue marbles

We are given that In her  experiment, she finds that she is twice as likely to pull a red marble as a blue  marble.

So, Number of red marbles = 2x

We are given that Marcia pulls 10 red marbles

So,

x=5

Hence She pulls 5 blue marbles

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,
