The gross profit margin is calculated using the following rule:
gross profit margin = total profit / total sales

Now, we need to get the values of total profit and total sale:
total profit = <span>9*8-(40+8)=24$
total sales = 9*8 = 72$

Now, we will substitute in the above equation:
gross profit margin = 24/72 = 1/3 = 0.3333334
% = 0.33333334*100 = 33.3334%</span>

Lapatulllka [165]

Answer:

343

Step-by-step explanation:

Finding? How many people with a library card should he expect in the population?

Important? Population = 700. Sample 1= 53%. Sample 2 = 51%. Sample 3 = 43%.

How? Average the 3 samples percentages together. The percent sign tells us what the sample size is (% = out of 100). Set up the proportions for library card to sample size and then library card to population. Cross multiply.

Can someone please answer this multiple choice questions numbers 2 , 12 and 13 please answer and please please show work
Vinil7 [7]

Answer:

2) D

12) C

13) D

Step-by-step explanation:

2)     4° C at 6:00 PM

     

A)  + 2°  - 6° = - 4°          4°  -  4°  = 0°       0° does not equal 4°        A  \neq Correct

B)   - 5°  + 1° = - 4°           4°  -  4°  = 0°       0°  does not equal 4°      B  \neq Correct

C)  + 6° - 4° =  + 2°          4° + 2° = 6°           0° does not equal 4°      C  \neq Correct  

D)  - 7°   + 7° = 0°            4°  + 0°  = 4°          4°  does equal 4°           D = Correct

The answer to question #2 is D

12)  M = -3

N ---->  M = 8.5 units

The only possible options for N are:

-3 + 8.5 = 5.5

-3 - 8.5 = -11.5

-11.5 is not a choice, so the answer to question #12 is C

13)  Scale: 1 inch = 70 yards

Abe walks 3.5 inches (on the diagram)

Multiply both sides of the scale by 3.5

3.5 * 1 inch = 70 * 3.5

3.5 inches = 245 yards

Abe walked 245 yards

The answer to question #13 is D

Hope this helps :)
