On Thursday is when DEF did better than it's average . Why? Because they were on time 10 flights and only delayed 1 flight .
Answer:
20
Step-by-step explanation:
Assume n is the number of times she pick a skittle out of the bag
The probability she pick out red : 8/n
The probability she pick out yellow : 12/n
=> The ratio of red and yellow skittle : 8/n : 12/n = 8/12 = 2/3, means every 2 red skittles we have 3 yellow ones.
But we have 50 skittles, so the likely numbers of reds in the bag is = 2*
= 20
Answer:

Step-by-step explanation:

First, use PEMDAS to distribute the -2 to the parenthesis.

Combine like terms on the right side.

Now, you may either subtract the f's or the constants. I'll subtract the constants first, meaning I will add 10 to both sides.

Now subtract the 2f from both sides.

Divide both sides by 10.

Simplify.
