Shana wants to use all 62 feet of the fencing she has to make a rectangular run for her dog. she decides to make the length of the run 20 feet. she writes and solves the equation 2 l + 2 w = 62 to find the width of the run. which statements are true of the solution? check all that apply.□ the value of w is 10 feet.□ the value of w cam be zero.□ the value of w cannot be a negative number.□ substitution is used to replace the variable l with a value of 20.□ the subtraction property of equality is used to isolate the term with the variable w.

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;
