Flipping two coins gives four possibilities: HH, HT, TH, TT
So P(TT)=1/4
So we'd expect a quarter of the trials to be two tails.

trials expected to be two tails.

You haven't given any options..but this is how i got it.
7000/175= 40
40*0.15=6
Answer:
Step-by-step explanation: If you are trying to figure out how many gallons the whole family uses, the answer is 99 gallons.The reason is is because it says 2.2 gallons a minute and it takes 9 minutes for a shower. So you multiply 9 by 2.2 which would give you 19.8. Then you multiply it by 5 isnce it says 5 people take a shower.
Solve for x:
-59 = 7 x
-59 = 7 x is equivalent to 7 x = -59:
7 x = -59
Divide both sides of 7 x = -59 by 7:
(7 x)/7 = (-59)/7
7/7 = 1:
Answer: x = (-59)/7
EACH Interior angle = 180 - (360 / number of sides)
EACH Interior angle = 180 - (360 /67)
EACH Interior angle =
