Your landscape crew can clear 620 square yards of overgrown landscape in an 8-hour day and can install 400 square yards of sod in an 8-hour day. If a customer needed one acre to be cleared and 280 square yards of sod to be installed, how long would your crew. need to complete the job at the site? (1 acre = 4,840 square yards). Select the correct response.​

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;

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)

too many. (jk)
