Write a polynomial function of least degree with integral coefficients that has the given zeros. 4, -6, 1

f(x) = x³ + x² - 26x + 24

Step-by-step explanation:

x = 4             x = -6              x = 1

x - 4 = 0        x + 6 = 0         x - 1 = 0

(x - 4) (x + 6) (x - 1) = 0

(x² + 2x - 24)(x - 1) = 0

x(x² + 2x - 24)  -1(x² + 2x - 24) = 0

x³ + 2x² - 24x  -x² - 2x + 24  = 0

x³ + x² - 26x + 24 = 0

answer: i guess 105 degrees?

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
