Two computers in an office are connected to the same printer. The two computers and the printer form an isosceles triangle. Each computer is 30ft away from the printer. Don wants to connect the two computers to each other and needs to calculate how much cable will be necessary. He knows that 30 feet of cable already joins each computer to the printer and each computer is 40 degrees from the printer. Find the amount of cable needed to connect the two computers.​

5/12, or 5: 12

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;
