Answer:
-26
Step-by-step explanation:
First find the area of the circle using A=pi*r^2
pi*36
Then divide this by 4 because the shaded region is 1/4 of the circle
(36*pi)/4=9*pi
Final answer: B
Answer: 4x² -4
Step-by-step explanation:
First, evaluate the exponent you'll get, + 4x² -5 then evaluate to get, 1+ 4x² -5. Next, subtract the numbers, 1 + 4x² -5 then to get, -4 +4x². Lastly, rearrange the terms, -4 +4x² turns into, 4x² -4!
Answer:
The probability that a randomly selected survey participant didn't got the flew = 0.75
Step-by-step explanation:
Students got the flu during Winter 2013 = 12 %
Students got the flu during Winter 2014 = 18 %
Students got the flu during both years = 5 %
Students got the flu at least in one year = 12 + 18 - 5 = 25 %
Students didn't got the flew = 100 - 25 = 75 %
⇒ The probability that a randomly selected survey participant didn't got the flew =
⇒ 0.75
This is the probability that a randomly selected survey participant didn't got the flew.
