22 divided by -2 and you get -11 then 22 divided by -11 = -2
This is what I get
First is to get them to perfect squares . R27 = r9^3
S30= s10^3
=(a-b)(a^2+ab+b^2)
Where a=r9 and b=s10 (R9-s10)((r9)^2+r9+s10+(s10)^2) Now simplify To get
(R9-s10)(r18-r9+s10+s20)
Answer:
P (A and B)=8/9
Events A and B are not dependent.
Step-by-step explanation:
Probability of A AND B means the the probability (favorable outcomes divided by total) of choosing someone who has/did BOTH A and B (not neither or only one of them). 16 did both, so the probability is 16/18 /2/2 = 8/9.
The events are independent (not dependent) because choosing A does not affect choosing B.
angle x= 77° because base angles on an isosceles triangle are the same.
hope that helped^^
The correct answer is choice d because you would divide x by 2 to get 70. then you do the same with y so 35/2 = 17.5
