Answer:
option C
Step-by-step explanation:
f(x)=-0.08x(x^2-11x+18)
Factor the parenthesis and find out the x intercepts
(x^2-11x+18)
We find out two factors whose product is 18 and sum is -11
-9 and -2 gives us product 18
-9 -2 gives us sum -11
(x^2-11x+18) =(x-9)(x-2)
f(x)=-0.08x(x^2-11x+18)
f(x)= -0.08x(x-9)(x-2)
set f(x) =0 and solve for x
-0.08x(x-9)(x-2) =0
-0.08x =0, so x=0
x-9 = 0 , so x=9
x-2 =0 , so x=2
x intercepts are (0,0) (2,0) and (9,0)
x intercepts are not repeating
so the graph crosses x -axis at x=0, 2,9
option C is correct

<u>Corrected Question</u>
Below is data collected from a random sample of 80 students regarding their fitness habits. If the entire school has 600 students, then what is a reasonable estimate for the number of students who consider themselves to have an average fitness habits.
Answer:
(D)330
Step-by-step explanation:
Out of a random sample of 80 students
44 considered themselves to have AVERAGE fitness habits.
Relative Frequency of Students with average fitness habits=44/80
Therefore, out of the total population of 600 students
Expected Number of Students with average fitness habits
=Relative Frequency of Students with average fitness habits X Total Population
<u>The correct option is D.</u>
The answer to 46 is = 10
Hope this helps some I don’t know the rest but have a good night
To me the answer is 6.4 and welcome get a good grade
Step-by-step explanation:
the number of students =24
number of boys =8
to have in fraction
