Step-by-step explanation:
g(f(-6)) = g( 4(-6)+3) =g(-21) = -21-2 =-23
The probability of rolling a 5 and rolling an odd number on a die is independent; rolling a 5 does not influence the probability of rolling an odd number the next time.
King or Jack is mutually exclusive; they cannot both happen at the same time.
Club or Queen is not mutually exclusive; they can happen at the same time.
King or Ace is mutually exclusive; they cannot both happen at the same time.
Answer:
2.5
Step-by-step explanation:
1st Quartile (Q1): 1
2nd Quartile (Q2): 2
3rd Quartile (Q3): 3.5
IQR = Q3 - Q1 = 3.5 - 1 = 2.5
Answer:
The first one is m A + 30 + 90 = 180
Second is 60
Step-by-step explanation:
A triangle’s added up angles ALWAYS equals 180.
The formula here is to subtract the two known angles from 180 and the answer leaves you with the unknown angle.
180 - 90 - 30 = A
So,
180 - 90 - 30 = 60
You can check by adding all the angles and it adding up to 180
90 + 30 + 60 = 180
