Paul Kim estimates that he will drive about 10,000 miles during the year and will have $3,460 in annual fixed costs. He projects

Mama L [17]

Answer:

The maximum annual variable cost he can have to reach his projection is $1,940

Step-by-step explanation:

Given;

Number of miles drive per year N = 10,000 miles

Total annual Fixed cost F = $3,460

cost per mile(rate) r = $0.54 or less

Total cost = fixed cost + variable cost

Total cost = cost per mile × number of miles

Total cost = r × N = $0.54 × 10,000 = $5,400

Let V represent the total variable cost per year;

F + V ≤ r × N

Substituting the values;

3,460 + V ≤ 5,400

V ≤ 5,400 - 3,460

V ≤ 1,940

The maximum annual variable cost he can have to reach his projection is $1,940

Answer:

0.731 < p < 0.775

Step-by-step explanation:

We have a sample proportion of 753/1000 = 0.753

We need to construct a 90% confidence interval for the population proportion. Since n > 30, we use the corresponding z-value of 1.645.

See attached photo for the formulas and construction of the confidence interval.

A farmer is tracking the amount of wheat his land is yielding each year. He finds that the function f(x) = −x2 + 20x + 75 models

mr_godi [17]

Answer:

Average rate of change: 0

Interpretation: No increment in yield from year 5 to year 15.

Step-by-step explanation:

The function that models the yield is:

$f(x)=-x^2+20x+75$

$f(15)=-(15)^2+20(15)+75=150$

$f(5)=-(5)^2+20(5)+75=150$

The average rate of change of f(x) from x=a to x=b is given by the formula;

$AOC=\frac{f(b)-f(a)}{b-a}$

The average rate of change from year 5 to year 15 is:

$\frac{f(15)-f(5)}{15-5}$

$\frac{150-150}{15-5}$

$\frac{0}{10}=0$

Interpretation: There has not been any increment in yield from year 5 to year 15.
