Macy’s is having a one-day 25% off special. If Bryan bought $110 worth of items, what would the final bill total after applying the discount of 25% and a sales tax of 6.5%? **Round to the nearest penny

87.86

Step-by-step explanation:

110x75/100=82.50

82.50x106.5/100=87.86

the square root of what number? if you add that, then someone will probably answer the question.

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;
