First simplify the expression into polynomial form,



Now factor into,

Which means the solutions are,


and then two complex solutions because determinant of the third factor
,

2, 67, and 83 are all prime. 63 and 91 are composite. For the bottom question the answer is A and B.
Answer: 0.866
Step-by-step explanation:
Mean = 4022
SD = 266
We are looking for the probability of samples 45g differ than the mean. Hence 2 probability combination:
X>4067 and X<3977
Calculate for Z we'll get Z = 0.16917 and -0.161917
Using Z formula we can find P(Z=0.17) = 0.433
Since both probability will occupy the same area, total probability is 0.433x2 = 0.866
