Answer:
c 35%
Step-by-step explanation:
2 green,5 yellow, 6 red,and 7 blue marbles
2+5+6+7 = 20 marbles
P(blue) = blue marbles / total marbles
= 7/20
= 35/100
=35%
To find the mean, add up all the test scores and divide by the number of tests:
524/10 = 52.4.
The correct answer is 63 i hope this helps out, have a nice day!!!
$25 times 45 equals $1125. Twice as many students as adults so, 45x2=90 90x$12= $1080 $1125+1080=$2205
4(x+3) = 5 + x, I believe this is the correct choice.
