f(x) = 64x³ - 125
Multiply each term in the second factor by each term in the first factor
= 4x(16x² + 20x + 25) - 5(16x² + 20 x + 25)
=64x³ + 80x² + 100x - 80x² - 100x - 125
= 64x³ - 125 ← difference of cubes
Answer:
The probability is 0.173
Step-by-step explanation:
The probability is of winning is 0.75 = 75/100 = 3/4
This means that the probability of losing is 0.25 = 25/100 = 1/4
So if they are two win 4 games, they will lose three
We can get this probability using the Bernoulli approximation of the binomial theorem
So here, we have
P(X = 4) = 7 C 4 * 0.75^4 * 0.25^3
= 0.173034667969
which is approximately 0.1730
Answer:
0.267 hours per dollar
Step-by-step explanation:
We know that for 15$ we can use a bike for 4 hours, so we divide both sides by 15 to get 0.267 hours per dollar.
Answer:
D) - 69q +74
Step-by-step explanation:
8 ( 10 - 6q ) + 3 ( -7q - 2)
= 80 - 48q -21q - 6
= 80 - 69q - 6
= - 69q +74
