Answer: The probability that a randomly selected teacher will make more than $40,542 per year is 0.82
Step-by-step explanation:
Looking at the information given, the population mean and population standard deviation are known. We would apply the formula
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = population standard deviation
From the information given,
µ = $42335
σ = 2000
x = $40542
The probability that a randomly selected teacher will make more than $40,542 per year is expressed as
P(x > 40542) = 1 - P(x ≤ 40542)
For P(x ≤ 40542),
z = (40542 - 42335)/2000 = - 0.9
Looking at the normal distribution table, the probability corresponding to the z score is 0.18
P(x > 40542) = 1 - 0.18 = 0.82

If two planes are perpendicular, they intersect. if two planes are parallel, they will never touch. hope this helps
Answer:
1)
5 OVER THE SECOND POWER=25
6XDIVIDEDBY25=4.167
-4 OVER THE THIRD POWER=-64
-64DIVIDEDBY9X=-7.1
2) 7X+8(X-5)
8TIMESX=8X
8TIMES-5=-40
7XPLUS8X=15X
15XDIVIDEDBY-40==2.67
62-12=50
FOR #2THE SIGN WILL BE TURNED THE OTHER WAY.....
3) -12TIMES3/4=-16X
-12TIMES2=-24
-16XDIVIDEDBY-24=1.5
45+3=48
EVERYTHING IN BOLD IS THE AWSNERS I JUST SHOWED MY WORK HOPE THIS HELPS GOOD LUCK.....
So number six the ratio is(3,3) I think and is Non-proportional
