Answer:
f(x) = x² + 8 - 16x
= x² - 16x + 8
= (x² - 16x + 64) - 64 + 8
= (x + 8)² - 56
Y = -4x +5 should be right!
Answer:
70%
Step-by-step explanation:
The probability it rains on at least one of the days is:
P = P(Sat & not Sun) + P(Sun & not Sat) + P(Sat & Sun)
P = (0.40)(1−0.50) + (0.50)(1−0.40) + (0.40)(0.50)
P = 0.20 + 0.30 + 0.20
P = 0.70
Another way to look at it is 1 − the probability that it doesn't rain on either day.
P = 1 − P(not Sat & not Sun)
P = 1 − (1−0.40)(1−0.50)
P = 1 − 0.30
P = 0.70
There is a 70% probability that it will rain on at least one day.
