Use the distributive property.
3(6 + x) = 24
18 + 3x = 24
3x = 6
x = 2
The mean should be about the same, because the sample is random
7/10 > 3/8
I found this by first finding a common denominator, so for this it will be 40. 10 can go into 40 four times, so you do 7x4 and that is 28, so 7/10 is 28/40.
3/8 is 15/40 because 8 goes into 40 five times, so you do 5x3 which is 15, so the fraction is 15/40. 15/40 is less than 28/40 because 28 > 15
First divide 6/(6+6+8) =0.3
Then multiple it by 100 to get the probability percentage 30%
The correct answer is B. 130,099.
Hope this helps!
