X^2-2x-8
(X-4)(x+2)
X–4=0 X+2=0
X=4 and X=-2
(4,-2) or (2,-4)
Both of the answer is correct
Hope i understood it right
b > 2
choices are
a. -12
b. 5
c. 1
d. -8
- so than b need being greater than 2 so this mean that choice b. is right sure with this number of 5
hope this will help you
The mean is 77
The median is 90
Answer:
The probability of 1 or less children from that group to learn how to swim before 6 years of age is 0.072
Step-by-step explanation:
In this case we need to compute the probability of none of these 12 children learns to swim before 6 years of age. This is given by:
p(0) = (1 - 0.312)^(12) = 0.688^(12) = 0.01124
We now need to calculate the probability that one child learns to swim before 6 years of age.
p(1) = 12*0.312*(1 - 0.312)^(11) = 3.744*(0.688)^(11)
p(1) = 3.744*0.01634
p(1) = 0.0612
The probability of 1 or less children from that group to learn how to swim before 6 years of age is:
p = p(0) + p(1) = 0.01124 + 0.0612 = 0.07244
THat would be B.
The product of 22 polynomials is a polynomial.
