Answer:
(x - 4)(x + 4)(x - 1)(x + 1)
Step-by-step explanation:
Given
- 17x² + 16
Use the substitution u = x², then
u² - 17u + 16
Consider the factors of the constant term (+ 16) which sum to give the coefficient of the u- term (- 17)
The factors are - 16 and - 1, then
u² - 17u + 16
= (u - 16)(u - 1) ← replace u by x²
= (x² - 16)(x² - 1) ← both factors are difference of squares
= (x - 4)(x + 4)(x - 1)(x + 1)
Answer:
P = 0.041553
Step-by-step explanation:
Probability that a student considers calculus exciting. = 0.84
Probability that a student finds calculus not exciting = 0.16
This is a binomial experiment.
p = 0.84 and n = 29
The probability of observing 28 or more of the students who consider calculus to be an exciting subject in our sample of 29 is given by:
P = 0.041553
