Sadie runs a farm stand that sells bananas and grapes. yesterday sadie sold 13 pounds of bananas and 15 pounds of grapes for a total revenue of $55.50. today she sold 46 pounds of bananas and 16 pounds of grapes for a total revenue of $131.50. write a system of equations that could be used to determine the price of each pound of bananas and the price of each pound of grapes. define the variables that you use to write the system.

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;
