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.
(2x+4) +(3x-1) +(x+1)=34
6x+4=34
x=5
AB=14, BC=14, AC=6
Definition of quadratic a formula
= a formula that gives the solutions of the general quadratic equation ax2 + bx + c = 0 and that is usually written in the form x = (-b ± √(b2 − 4ac))/(2a)
Answer:
y + 2 = -3(x - 7)
Step-by-step explanation:
Write the equation using the point slope form
. Substitute m = -3 and (7,-2).

Answer:
88
Step-by-step explanation:
hello,
we need to replace x by 6 and y by -10 so it comes
3*(6)-7*(-10)
= 18 + 70 = 88
hope this helps
