In a certain city , the hourly wage of workers on temporary employment crontracts is normally distributed. The mean is $15 and t
Doss [256]

Answer:

16%

Step-by-step explanation:

The mean is $15 and the standar deviation is $3.

mean = 15  and SD = 3

We need to find percentage less than 12 per hour

P(x<12)= P(x=12)

to find P(x=12) we find z-score

z= \frac{x-mean}{SD} =\frac{12-15}{3} =-1

Now use z-score table . z-score = 0.1587

P(x=12)=0.1587

To get percentage we multiply by 100

0.1587 * 100 = 15.87 = 16%

$750 loan 7% a year three years of no payments how much interest are you paying?
Anastaziya [24]

Answer:

$157.50

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 7%/100 = 0.07 per year,

then, solving our equation

I = 750 × 0.07 × 3 = 157.5

I = $ 157.50

The simple interest accumulated

on a principal of $ 750.00

at a rate of 7% per year

for 3 years is $ 157.50.

The sale price of a router is 35% Off the regular price. The sale price is 117$. What was the regular price ?
sladkih [1.3K]

Okay, the equation would be: What is 35% of $117

Proportion:

\frac{x}{117} \frac{35}{100}

We multiply:

117 x 35 = 4095

Now we divide:

4095 / 100 = 40.95

Then we add:

40.95 + 117 = $157.95

and that's your answer!

I hope this helps! :)
