An online furniture store sells chairs for $100 each and tables for $400 each. The store must sell no less than $5400 worth of chairs and tables each day. Write an inequality that could represent the possible values for the number of tables sold, t, and the number of chairs
sold, c, that would satisfy the constraint.
O A. 1000+4000 5400
OB. 1000+400ts 5400
O C. 1000+400t> 5400
O D. 1000+400t<5400

D

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;
