Faaria wants to get some custom T-shirts printed for her basketball team. Shirts cost $10 each for the first 6 shirts and $5 each for every shirt over 6. What is the slope of the graph between 7 and 15 shirts?

The slope on the graph is the price, and it is sloping because the price is cheaper.

Step-by-step explanation:

$10 = 1-6 shirts (amount)

$5 = 7+ shirts (amount)

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;
