Answer:
1/169
Step-by-step explanation:
There are 4 aces in a deck of 52.
The probability that the first card is an ace is 4/52.
Since the card is replaced, the probability that the second card is an ace is also 4/52.
The total probability is (4/52) (4/52) = 1/169.
Answer:
Average rate of change = 0
Step-by-step explanation:
f(z) = -2z^2 - 12z - 19
a = -4 and b = -2
[f(b) - f(a)] / (b-a)
[-2(-2)^2 - 12(-2) -19] - [-2(-4)^2-12(-4)-19] / (-2 -(-4))
(-8+24-19) - (-32+48-19) / 2
(-8+24-19+32-48+19) / 2 = 0/2
