Marti sells tacos and burritos from a food truck at the farmers market. She sells burritos for $3.50 each and tacos for $2.00 each. She hopes to earn at least $120 at the farmers' market this Saturday.

Let x equal the number of burritos that Marti sells, and let y equal the number of tacos that Marti sells. Select the linear inequality that represents the solution to this problem.

Question 4 options:

3.5x + 2y ≤ 120

3.5x + 2y ≥ 120

3.5(x + y) > 120

2x + 3.5y ≤ 120

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;

step-by-step explanation:

the answer is 89 d
