Find the value of z.
Answer:
The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation. As the formula shows, the z-score is simply the raw score minus the population mean, divided by the population standard deviation.\

An elevator descends into a mine shaft at the rate of 5 m/min. If the descend starts from 15m above the ground, by how long will it take to reach 350 m deep from the ground?
Answer:
Step-by-step explanation:
First we need to do 350 - 15 since 350 is our total and we already started at 15m.
Next divide the remainder (335) by 5 because that’s how fast we are moving, the final answer is 67 minutes.
Erin earns $2 200 per month her deduction amount to 28% of her paycheck. How much does she take home each month
Answer:
1584
Step-by-step explanation:
The take-home salary would be $1584 each month if Erin earns $2200 per month her deduction amount to 28% of her paycheck.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
Erin earns $2200 per month.
The deduction amount to 28% of her paycheck.
Let's assume the 28% is deducted from the monthly salary.
The total dedcution = 28% of 2200
The total dedcution = (28/100)x2200
The total dedcution = 0.28x2200
The total dedcution = $616
Total net amount = Take home = 2200 - 616
Take home = 2200 - 616
Take home = $1584
Thus, the take-home salary would be $1584 each month if Erin earns $2200 per month her deduction amount to 28% of her paycheck.

Step-by-step explanation:
formula for slope is [tex]\frac{y2-y1}{x2-x1}[/tex]
So,
[tex]\frac{6-(-7)}{1-(-5)}[/tex]
which leaves you with
[tex]\frac{13}{6}[/tex]
find ∅ round to the nearest degree
A. 24°
B. 66°
C. 64°
D. 26°
Answer:
C
Step-by-step explanation:
Using the cosine ratio in the right triangle
cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{7}{16}[/tex] , then
θ = [tex]cos^{-1}[/tex] ([tex]\frac{7}{16}[/tex] ) ≈ 64° ( to the nearest degree )

Write this exponential statement in logarithmic form for an investment at 15% quarterly. Then use change to base to find double time in yr.
Answer:
a) Log ( 2 ) = 4t Log ( 83/80 )
b) 4.7 years
Step-by-step explanation:
Attached below is the detailed solution
a) exponential statement in log form for an investment at 15% quarterly
Log ( 2 ) = 4t Log ( 83/80 )
n = 4 , r = 15
b) using change to base to find double time in yr
Double time in yr
t = Log ( 2 ) / 4log ( 83/80 )
= 4.7 years
