A group of 4 students share 8/12 of a pizza how many pieces will each student get?
TEA [102]

Answer:

1/6 of a pizza

Step-by-step explanation:

We need to take the amount of pizza and divide by the number of students

8/12 ÷ 4

Copy dot flip

8/12 * 1/4

8/48

igor_vitrenko [27]

Answer:

0.0062

Step-by-step explanation:

Find the standard error.

σ = 20 / √100

σ = 2

Find the z-score.

z = (x − μ) / σ

z = (70 − 65) / 2

z = 2.5

Find the probability.

P(Z > 2.5) = 1 − 0.9938

P(Z > 2.5) = 0.0062

Are these two expressions equivalent?<br> 2 • (37) and (2•3) • 7
liubo4ka [24]

Answer:

No

Step-by-step explanation:

2*37 equals 74

(2*3)*7 is a different case. You first have to do what is inside the parentheses. 2*3 is 6. 6*7 equals 42. You wouldn't distribute in this case, because of the multiplication position and PEMDAS.

Hope this helps!
