Answer:
33x^2 - 50x + 8
Step-by-step explanation:
Multiply the length times the width.
Length: 3x - 4
Width: 11x - 2
(3x - 4)(11x - 2)
33x^2 - 50x + 8
The y-intercept is 4. Divide by three to get y alone (12/3=4)
Step-by-step explanation:
27/100 is the fraction of 0.27

k(x,9) = (-10,-6)
k*x = -10
k*9 = -6 Distributive property of multiplication
k*9 = -6
k = -6/9
k = -2/3 Get the value of k to solve for the value of x.
k*x = -10
-2/3 * x = -10
x = -10 ÷ -2/3
x = -10 * -3/2
x = (-10 * -3)/2
x = 30/2
x = 15 Choice D.
The probability that the participant was a nonsmoker is 25%.
<h3><u>Probability</u> </h3>
Given that at the beginning of a certain study of a group of persons, 15% were classified as heavy smokers, 30% as light smokers, and 55% as nonsmokers, and in the five-year study, it was determined that the death rates of the heavy and light smokers were five and three times that of the nonsmokers, respectively, to calculate, if a randomly selected participant died over the five-year period, the probability that the participant was a nonsmoker, the following calculation must be performed:
- 15 x 5 = 75
- 30 x 3 = 90
- 55 = 55
- 55 + 90 + 75 = 220
- 220 = 100
- 55 = X
- 55 x 100 / 220 = x
- 5500 / 220 = X
- 25 = X
Therefore, the probability that the participant was a nonsmoker is 25%.
