Data on first test: 50, 50, 50, 50, 50
Mean = 250 / 5 = 50

In the next test, Data is: 50, 50, 50, 50, 100

Mean = sum of data / number of data
Mean = 50 + 50 + 50 + 50 + 100 / 5
M = 300 / 5
M = 60

In short, Your Answer would be 60

If You're looking for combined progress (average of class then, it would be: 50 + 60 /2 = 110/2 = 55

Hope this helps!

Peter's Party Zone sells cups in packages of 666 and plates in packages of 888.
Amiraneli [1.4K]
Prime factorize the two numbers:

666 = 2 x 3 x 3 x 37
888 = 2 x 2 x 2 x 3 x 37

Notice I lined up all the numbers into columns. If they appear for both numbers they are paired. The lowest common multiple is the product of all the unique columns:

LCM = 2 x 2 x 2 x 3 x 3 x 37 = 2664

You can use this strategy for as many numbers as you want. Also, you could find the greatest common factor by multiplying only the paired columns.

Kipish [7]

Answer:

x=-5/3

Step-by-step explanation:

we have

x-\frac{2}{3} x-\frac{1}{2}=\frac{1}{3}+\frac{5}{6}x

Solve for x

Multiply by 6 both sides to remove the fractions

6x-4x-3=2+5x

Combine like terms

2x-3=2+5x

5x-2x=-3-2

3x=-5

x=-5/3
