To find the GCF, you have to list all factors of each number and find the first common one.

12 = 1, 2, 3, 4, 6, 12

28 = 1, 2, 4, 7, 14, 28

36 = 1, 2, 3, 4, 6, 9, 12, 18, 36

the GCF of numbers 12, 28, 36 is 4.

hope this helps, God bless!

Use PEMDAS.

Parenthesis first.

(-15)-(-12)+3-(-9)

Next multiply,

(-15)+12+3+9 (two negatives get you a positive)

Finally, add and subtract:
-15+24=9

You get 9 as your answer.

Hope this helps!

AleksandrR [38]

Answer:

(29-23)²/23 + (16-23)²/23 + (19-23)²/23 + (28-23)²/23

Step-by-step explanation:

Given :

n(American) = 29

n(Chinese) = 16

n(Mexican) = 19

n(Italian) = 28

Expected value = (29 + 16 + 19 + 28) / 4

Where, 4 = sample size

Expected value, E = 23

χ² = (Observed value - Expected value)² / expected value

χ² = (29-23)²/23 + (16-23)²/23 + (19-23)²/23 + (28-23)²/23
