Answer : B
The question is asking you to find how many real roots there are. You use factoring to find the roots of this polynomial function. The steps for factoring are to factor out the GCF, factor, and solve for the x’s.
You then determine negative and positive roots.

Answer:
x - 7 < - 12 A: -6 or less ... -7, -8, -9 etc
-9x (90) A: -10
3 + v > -9 A: -11 or more ... -10, 1, 0, 1238 etc
Step-by-step explanation:
1. if it has to be less than -12 the number must be farther left then -12
2. negative times negative = positive
3. use any number higher than -9
(4 3/8) + (5 1/3)
(4+5)(3/8 + 1/3)
9 + (17/24)
she ran 9 17/24 miles total
Answer:
a) 0.226
b) 0.613
c) Part(a)
d) Unusual event
Step-by-step explanation:
We are given the following in the question:
x: 0 1 2 3 4 5 6 7 8
P(x): 0.000 0.003 0.016 0.054 0.121 0.193 0.226 0.193 0.121
x: 9 10 11 12
P(x): 0.054 0.016 0.003 0.000
a) Probability of exactly 6 Mexican-Americans among 12 jurors.
Thus, 0.226 is the probability of exactly 6 Mexican-Americans among 12 jurors
b) Probability of 6 or fewer Mexican-Americans among 12 jurors
Thus, 0.613 is the probability that 6 or fewer Mexican-Americans among 12 jurors.
c) The result from part (a), because it measures the probability of exactly 6
successes.
d) Unusual event
An event is said to be unusual if the probability of event is less than 0.5.
Since
Thus, it is an unusual event as the probability is less than 0.5
