Y=12x+14 would be the equation for slop intercept form equation.
85% liked => 15% didn't like
30 = 15% of x
30 = 0.15 x => x = 30 / 0.15 = 200. This is the total number of students at the library.
Then 200 - 30 = 170 is the number of students whom did like reading mistery stories.
Answer: 170.
I gotchu bro. First you want to expand 5 x 10^-6 which is (HINT: 10... and then move the decimal 6 to the LEFT) so: 0.000010 (you can drop the 0 after the 1)
So then, Take 0.04 and divide 0.00001 to get your answer.
(U got a test so im not gonna answer it for u. U got this)
First, we know there are 12 girls because 6+6=12
Then for probability we do the part divided by the whole
# of girls in red hats/total # of girls
SO the answer is 6/12
Hope this helps!
