3.Juniper wants to make a new rectangular garden in her backyard that has a length that is 2 more than twice the width. She needs to install a chicken wire fence to keep the rabbits out and away from her tomatoes. She bought a roll of chicken wire that is 64 ft long. Write an inequality to show how to find the possible dimensions of her new garden. (You do not need to solve it but be sure to define both your variables!)

i really dont know

step-by-step explanation:

you're missing vital information, add to it so we can solve this problem for you.

step-by-step explanation:

the anwser is d) 75°

step-by-step explanation:

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;
