Answer:
y = 0.5 (x^2 -2x + 16) has a y-intercept of 8.
Step-by-step explanation:
The x-coordinate of every y-intercept is zero. To determine which of the four quadratics given here has a y-intercept of 8, we need only substitute 0 for x in each; if the result is 8, we've found the desired quadratic.
O y = 0.5(x + 2)(x + 4) becomes y = 0.5(2)(4) = 4 (reject this answer)
O y = 0.5 (x - 2)(x + 8) becomes y = 0.5(-2)(8) = -8 (reject)
O y = 0.5(x2 -2x - 16) becomes y = 0.5(-16) = -8 (reject)
O y = 0.5 (x2 -2x + 16) becomes y = 0.5(16) = 8 This is correct; that '8' represents the y-intercept (0, 8).
The solution is, the probability that both cards are red is 5/22.
Probability can be defined as the ratio of the number of favorableoutcomes to the total number of outcomes of an event.
here, we have,
given that,
Gregg has 12 cards.
Half are black, and half are red.
i.e. red = 6 & black = 6.
He picks two cards out of the deck.
now, we have,
Probability of a red card out of 12 cards = 6/12 = 1/2
Now, probability of a red card of 11 cards = 5/11
so, we get,
Combined probability = 1/2 * 5/11 = 5/22
Hence, The solution is, the probability that both cards are red is 5/22.
