Answer:
c. 18.36-21.64
Step-by-step explanation:
Using the following formulas the lower and upper limits of the interval are calculated
Lower limit = mean - (standard deviation /√sample size)* Zr
Upper limit = mean + (standard deviation /√sample size)* Zr
Zr depends on confidence interval
Zr for 90% = 1.645
then
Lower limit = 20 - (4 /√16)* 1.645 = 18.355 ≈ 18.36
Upper limit = 20 + (4 /√16)* 1.645 = 21.645 ≈ 21.64

Answer:
2
Step-by-step explanation:
The graphs have two (2) points of intersection. Each point of intersection is a solution to the system of equations. The coordinates of that point satisfy both equations simultaneously.
There are 2 solutions to the graphed system of equations.
