a company pays its employees and average hourly wage of 36.25 with a standard deviation of 6.50 more than 23.22 of 36 employees

Yuliya22 [10]

Answer:

P [ X > 23,22 ] = 0,8798 or P [ X > 23,22 ] = 87,98 %

Step-by-step explanation:

P [ X > 23,22 ] = 1 - P [X ≤ 23,22 ]

P [X ≤ 23,22 ] = ( X - μ₀ ) / σ /√n

P [X ≤ 23,22 ] = ( 23,22 - 36,25 )/ 6,50/√36

P [X ≤ 23,22 ] = - 13,03 *6 / 6,50

P [X ≤ 23,22 ] = - 12,02 or P [X ≤ 23,22 ] = 12,02 %

(note the - sign only mean that values on the left tail of the bell shape curve)

Then

P [ X > 23,22 ] = 1 - 0,1202

P [ X > 23,22 ] = 0,8798 or P [ X > 23,22 ] = 87,98 %

Answer:

Step-by-step explanation:

7/15 + 3/5

I'd multiply 3/5 by 3 so that both of the denominators (bottom number) are the same.

Now all we have to do is add the Numerators tog

7/15 + 9/15ether (the top number)

7/15 +9/15 = 16/15 or 1 1/15

On a scale drawing of a fence, 3.75 inches represents 12 feet. Estimate the actual length of a second fence that is 2.8 in the d

MA_775_DIABLO [31]

In order to find the scale they are using first you must divide 12 by 3.75.

But since we get to estimate, the 3.75 will be made into a 4 because it's the whole number closest to 3.75.

12/4=3

Take your 3 inch scale and multiply it by 3 (we are using 3 instead of 2.8 because it's a whole number) to get the real life fence size.

3x3=9

The fence is about 9 feet.
