Answer: P1: 17.61 P2: 14.66
Step-by-step explanation:
P1: take total divide by how many numbers used : 229 divided by 13 =17.61
P2: take total divide by how many numbers used : 88 divided by 6= 14.66
(x+108) and (x+88) are supplementary angles. This means that they add to 180.
(x+108) + (x+88) = 180
Solve for x:
2x + 196 = 180
2x = -16
x = -8
youre answer is b
point slope formula is y-y1=m(x-x1)
m=slope
x1= coordinate x
y1= coordinate y
We need to set up a system, rather than a single equation, because there are two variables involved.
The first equation represents the fact that the two numbers are in a 3:2 ratio:
The second equation represents the fact that their sum is 35:
So, we have the following system:
Using the expression for x in the first equation, the second one becomes
which implies
There are a total of 16 movies to choose from and 6 of them are comedy. This means that you have a 38% of choosing comedy. But the chances of you not choosing comedy is 62%. And since your friend is also choosing, the chance of neither of you not choosing is cut in half.
So, the final answer of neither of you choosing comedy is 31%
(I don't know whether it's dependent or independent)
