Answer:
No not correct
Step-by-step explanation:
We are given information that Maya came to know that 0.63 pf Pal school is female and 0.47 of Elm school is female.
Without knowing the total number of students in each school, we cannot conclude that 0.63 is greater than 0.47
For example, say number of students in Oak school be 100, and in Elm school be 200
Females in Oak school = 0.63(100) =63
Females in Elm school = 0.47(200) = 94
We find that there are more females in Elm school
So with the information given, we cannot conclude she is correct , there are chances for her being wrong also.
The cross section of the satellite dish is an illustration of a quadratic function
The quadratic function that models the cross-section is y = 1/6(x^2 - 9)
<h3>How to determie the equation of the cross-section?</h3>
The given parameters are:
Width = 6 feet
Depth = 1.5 feet
Express the width the sum of two equal numbers
Width = 3 + 3
The above means that, the equation of the cross section passes through the x-axis at:
x = -3 and 3
So, we have:
y = a(x - 3) * (x + 3)
Express as the difference of two squares
y = a(x^2 - 9)
The depth is 1.5.
This is represented as: (x,y) =(0,-1.5)
So, we have:
-1.5 = a(0^2 - 9)
Evaluate the exponent
-1.5 = -9a
Divide both sides by -9
a = 1/6
Substitute 1/6 for a in y = a(x^2 - 9)
y = 1/6(x^2 - 9)
Hence, the quadratic function that models the cross-section is y = 1/6(x^2 - 9)

Answer:
3
Step-by-step explanation:
3 is the coefficient of c as it is a constant, whereas a and b are variables, subject to change.
So if a person has 1/8 of a pitcher then you have 8 people per pitcher. Then if you have 5 pitchers you do 5 x 8 and get 40 so 40 people will be served. Hope this helps :)
