Since you have two numbers that have a (x) at the ends of them, you add those first then add seven which will end up being 9x+7
Answer:
We have 10 sections, we can assume that the probability of hitting each of one of them is the same.
we have 9 grey slices and 1 white slice, then the probability of landing in a grey slice is equal to the number of grey slices divided by the total number of slices:
P(X) = 9/10 = 0.90
The probability of not landing in a grey slice is equal to the probability of landing in the white slice, this is:
P(not X) = 1/10 = 0.10
Also, when you have only two events, you can calculate this as:
P(not X) = 1 - P(X) = 1 - 0.90 = 0.10
Answer:30 boys
Step-by-step explanation: There are 120 students, three-fourths are girls. Nine out of twelve is equal to three fourths, if you add a zero to the end of twelve and nine you get 90 out of 120, which is how many girls there are. If you subtract 90 from 120 you get 30 or one-fourth. The number of boys is equal to one-fourth because there is only one-foutlrth left. So, there are 30 boys.
