Answer:
Step-by-step explanation:
I assume you mean consecutive picks without replacement.
There are 10 girls and 22 students so
P(GG)=(10/22)(9/21)
P(GG)=90/462
P(GG)=15/77
You have to do whats in the parentheses from left to right then subtract the answer you get by 20
(9x10) - (30+30)
90 - 60 = 30
8 x (12+5) -7^2
17
17-49
18 x -32
= -576.
You have to use pemdas for your check off
P=parentheses
E=exponet
M=multiplication
D=division
A=add
S=subtrabt
HOPE IM CORRECT
9 is the answer!!!!!!!!!!!!!!!!!!!!!!
Answer:
undefined because the change in y is zero since they do not change, therefore it is undefined
Hello!
You solve this like an algebraic equation
You first distribute the 4 and 2
4x - 20 = 2x - 20 + 2x
Combine like terms
4x - 20 = 4x - 20
subtract 4x from both sides
-20 = 0x - 20
Add 20 to both sides
0 = 0
This means that there are infinite solutions to the equation.
Hope this helps!
