D) because “y is” means “y equals” leaving only 2 choices, and it said “6 less than the independent variable, 6. (Y=6-x)
The 3rd set, no x or y numbers are repeated.
Let T = the distance, in miles, a tire lasts
T ~ N(70000,4400<span>²</span>)
P(T

≈ P(Z

1.14)
= 1 - P(Z < 1.14)
≈ 1 - 0.8729
= 0.1271
15(1 + n/100) = 75(1 - n/100)
15 + 0.15n = 75 - 0.75n
0.15n + 0.75n = 75 - 15
0.9n = 60
n = 60/0.9 = 66 2/3%
6% of n = 0.06 x 66 2/3 = 4
Using it's critical points, it is found that the least possible degree of the polynomial graphed above is 4.
<h3>What are the critical points of a function?</h3>
The critical points of a function are the values of x for which:

At these critical points, the behavior of the function changes from increasing to decreasing or vice versa.
If a function has n critical points, the least possible degree is of n + 1.
From the changes in behavior of the graph, the function has critical points at:
.
The function has 3 critical points, hence the least possible degree of the polynomial graphed above is 4.
