Here are 5 number cards 2 5 7 8 9 one of the cards is removes and the mean average of the remaining four number cards is 6. which card was removed? you must show your working

7

Step-by-step explanation:

If one of the cards is removes and the mean average of the remaining four number cards is 6, then their sum is

The sum of all five cards is

Since then the card with number 7 is removed.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

there would only be 50 odd numbers between 1 and 100 so therefor there would be 50 even so that would only be 50 odd numbers.
