Answer:
-3, -1, 1
Step-by-step explanation:
The values of x when f(x) = 0 are the points on the graph when the curve intercepts the x-axis.
From inspection of the graph, the curve intercepts the x-axis at
x = -3, x = -1 and x = 1
Answer:
1/ 8
Step-by-step explanation:
Given that:
Number of red cards in deck = 26
Number of diamonds in deck = 13
Number of cards in deck = 52
Recall :
Probability = required outcome / Total possible outcomes
Probability of choosing a red :
P(red) = 26 / 52 = 1/2
With replacement :
Probability of diamond :
P(diamond) = 13 / 52 = 1/4
Hence,
Probability of first card red, then second card diamond equals
P(red) * P(diamond)
1/2 * 1/4
= 1/8
