Answer:
A
Step-by-step explanation:
The first thing to notice is the question says it is given that the person is between the ages 23 and 60, so we only care about those people. So then we want to know how likely it would be to pick someone with over 50 messages a month. So what you would do is take the amount of people who are between 23 and 60 and send over 50 text messages, and divide that by the total amount of people 23-60 (since that is the pool of people we have). Doing so we find there is 229 people aged 23-60 which then makes the answer 157/229 or A.
The number of the zeroes of the function will be 3. Then the zeroes of the functions are -2, 1, and 2.
<h3>What is a factorization?</h3>
It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The equation is given below.
f(x) = x³ - x² - 4x + 4
Then the factor of the equation will be
f(x) = x²(x - 1) - 4(x - 1)
f(x) = (x² - 4)(x - 1)
f(x) = (x² - 2²)(x - 1)
f(x) = (x + 2)(x - 2)(x - 1)
Then the solution to the equation will be
(x + 2)(x - 2)(x - 1) = 0
x = -2, 1, 2
The number of the zeroes of the function will be 3. Then the zeroes of the functions are -2, 1, and 2.
