Answer:
(507.05, 592.95)
Step-by-step explanation:
Given data:
sample mean = $550, sample standard deviation S = $60.05
95% confidence interval , n = 10
For 95% confidence interval for the mean
mean ± M.E.
where M.E. is margin of error =
Substituting the values in above equation
= 2.62×18.99
=42.955
= 550±42.95
=(507.05, 592.95)
Answer:
Step-by-step explanation:

- Change the division operation to multiplication.
- Flip the second fraction.
Option A : a+o = 92 , 4a+2o = 284 is the right answer
Step-by-step explanation:
Let o be the number of oranges sold on Friday and
a be the number of apples sold on Friday
So,
A total of 92 was sold on Friday will yield the equation
On Saturday,
4 times the number of apples = 4a
2 times the number of oranges = 2o
So,
Hence,
The system of equations is:
Option A : a+o = 92 , 4a+2o = 284 is the right answer
