When isabel began her book-selling business, she stored her inventory in her garage. now that her business has grown, she wants to rent warehouse space. lisa owns a large warehouse nearby and can rent space to isabel. the area of the warehouse is 8,100 square feet. lisa is willing to rent isabel as little as 100 square feet of the space or up to as much as the entire warehouse. her only requirement is that all spaces must be square. the total length of each row of bookshelves will be "4" /"5" of the length of the storage space. let x be the area of the space that isabel rents and f(x) represent the total length of a row of bookshelves. how would you find the length of a row of bookshelves? (3 points) write a function that expresses f(x). (10 points)

b

step-by-step explanation:

n

step-by-step explanation:

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart

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;
