Can anyone help? with these probelms. Denise Irwin drove her vehicle 10,500 miles. Fixed costs totaled $2,452. Variable costs totaled $893. a. What was the total annual cost? (2 points) b. What was the cost per mile? (4 points)

Lease an SUV for 48 payments of $294. Deposit of $1,189. Title fee of $90. A license fee of $125. What is the total lease cost?

Denise = total cost $3,345.00 per mile cost is 0.3185 or 32 cents per mile

Total Lease cost = $15,516

Step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
