Answer:
Jaime's. Interval not centered around the point estimate.
Step-by-step explanation:
When constructing a confidence interval based on a point estimate, the obtained point estimate must be the central value of the interval.
For Jaime's interval
Lower bound = 0.078
Upper Bound = 0.193

For Mariya's interval
Lower bound = 0.051
Upper Bound = 0.189

For a point estimate of 0.12, only Mariya's interval is adequate since Jaime's is not centered around the point estimate.
Answer:

Step-by-step explanation:
This is a subtraction between polynomials, since both functions are polynomials, hence, to solve the problem with need to perform the subtraction, by coefficients.

By performing the subtraction, we have:

First write the inequality: 15

4.75x +3.50
Then to solve, first subtract 3.50 from both sides to get:
11.50

4.75x
Then divide by 4.75 to get 2.42, and since you can't buy .42 of a bag of fruit, you round down. So your final answer would be 2 bags of fruit.
