A farmer raises goats and cows. Each goat requires 400 square feet of grazing area and each cow requires 1,200 square feet of grazing area. The farmer has 36,000 square feet for grazing area. Write a function to
represent the combination of goats and cows that the farmer can raise. Let a represent the number of goats,
and y represent the number of cows.

this might get deleted, sorry. it has to be an actual question. if you really wanted to give someone free points, ask a question like "why does the sky look blue, and the sun is yellow to our eyes? "

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;

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
