Every bottle costs $1.50
x = Number of bottles sold
x(1.50) = x times 1.50
Answer:

Step-by-step explanation:
<u>Area of trapezoid</u>
Given a trapezoid shape whose parallel sides measure b1 and b2 and whose height (perpendicular to the base) is h, then the area of the trapezoid is given by

The dulcimer has the following dimensions


and height h
Thus

Operating


Is the required polynomial
Coefficient of variation is calculated by dividing the standard deviation by the mean multiplied by 100. Given a data set with mean equal to 60 and variance equal to 9, we can calculate the coefficient of variation by finding the value of the standard deviation which is the square root of the variance. so standard deviation is equal to square root of 9 which is 3. Then, the coefficient of variation is equal to 3/60*100 which is equal to 5%.
We are given

Since, we have to solve for F
so, we will isolate F on anyone side
step-1:
Multiply both sides by 60


step-2:
Divide both sides by 11


step-3:
Add both sides by 32


so, we get
