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
Answer:
-2x + 4y = 16.
Step-by-step explanation:
y = 2/4x+ 4 Multiply through by 4:
4y = 2x + 16
-2x + 4y = 16 is the standard form.

Answer:
The other side = 
units
Step-by-step explanation:
A right triangle has a side of length 
units and;
the hypotenuse is 
According to Pythagorean theorem,
a² + b² = c² , where a and b are the two legs of a triangle and c is the hypotenuse.
Lets say a² = 
and c² = (
b² = c² - a²
b² = 
- 
= 
So b = 
= units.
So the other side = units.
