Answer:
0.658 is the probability that a sample 90 test takers will provide a sample mean test score within 10 points of the population mean of 502.
Step-by-step explanation:
The following information is missing:
The standard deviation of population is 100.
We are given the following information in the question:
Population mean, μ = 502
Standard Deviation, σ = 100
Sample size, n = 90
Standard error =
Formula:
P(test score within 10 points)
0.658 is the probability that a sample 90 test takers will provide a sample mean test score within 10 points of the population mean of 502.
Answer:
-1, 0, 1, 2
Step-by-step explanation:
-1 + 0 + 1 + 2 = 2
Given two points (X1,Y1) and (X2,Y2) on a line, the slope =(Y2 - Y1) /(X2 - X1).
You are given the points (1,3) and (3,-2). Implying X1 =1 , Y1 =3, X2=3, Y2=-2
Use the formula for the slope above to answer the question. If you still have problems getting the correct answer, ask for more help.
Your answer should be a negative fraction or decimal if you are using a calculator.
Answer:
21
Step-by-step explanation:
Answer:
m<1=?
m<2=4x-20..........(1)
m<4=3x-11.............(2)
Step-by-step explanation:
we have
- m<2=m<4(corresponding angle of parrelelogram are equal)
- 4x-20=3x-11
- 4x-3x=20-11
- x=9
again.we have
<1+<2=180(co-interior angle)
<1=180-<2=180-(4×9-20)=180-16=164
