When you minus the 23.75 from 2000 you get 1976.25 and then divide that amount by 8 to get $247.03 per person.
Answer:
The sample mean is 3.48 and the margin of error is 0.44.
Step-by-step explanation:
We know that the confidence interval is written in the form "x − E to x + E", meaning x: sample mean or estimator, and E: margin of error.
To calculate the mean, we can calculate the average of both bounds of the confidence interval:
![X=(UL-LL)/2=(3.92+3.05)/2=6.97/2=3.48](https://tex.z-dn.net/?f=X%3D%28UL-LL%29%2F2%3D%283.92%2B3.05%29%2F2%3D6.97%2F2%3D3.48)
With one of the bounds, we can calculate the margin of error E
![UL=X+E\\\\E=UL-X=3.92-3.48=0.44](https://tex.z-dn.net/?f=UL%3DX%2BE%5C%5C%5C%5CE%3DUL-X%3D3.92-3.48%3D0.44)
Answer:
324
Step-by-step explanation:
1.5% of 1200 = 18
18x18 = 324
Answer:
a
Step-by-step explanation:
Easey peasy
oposite angle is equal
other angles are supplementary (supplementary means add to 180, and a straight line=180 so if you look at 2 lines intersecting and think for a little bit, you wiill see why)
oposite angle=30
other angle is adds to 180
30+other=180
subtract 30
other=150
other is oposite other other
other=other other
150=other other
angles are
150,30,150
