The number of cups of sugar (y) in a cookie recipe is proportional to the number of cups of flour (x). The recipe calls for 1.25 cups of sugar for each cup of flour. Which equation could represent the cups of sugar required for a batch of cookies? There are _
cups of flour for _ batches.

The slope is _
.

The y-intercept is _
.

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;
