Use the distributive property
(4x + 2)3
Distribute.
3 * 4x = 12x
3 * 2 = 6
<u>Answer</u>
12x + 6
Answer:
99.25
Step-by-step explanation:
3 times 25.50 = 76.5
2 times 4.75 =
3 times 2.25 = 6.75
3.5 + 3 + 76.5 + 9.5 + 6.75 = 99.25
In total, they spent $99.25 at the football game.
Answer:
1. 1/4
2. 1/2
Step-by-step explanation:
If there are equal numbers of males and females, we can simplify that by saying there's one male and one female for each coat color.
1. What's the probability that both are males?
Well, there's a 1/2 chances the light-colored coat bear is a male and there's also a 1/2 chances the dark-colored coat bear is a male. So, we can make this reference table:
<u>Light Dark</u>
<em>Male Male</em>
Male Female
Female Male
Female Female
As you can see, the probability that both of the spotted bears are males is 1/4 (1/2 * 1/2).
2. If the light-colored bear, what are the odds both are males?
If we know for sure the light-one is male, then there's 1/2 chances the other is too, refer to the table above to verify.

Step-by-step explanation:
From the question we are told that
The number of players in Taft High School is t = 8
The number of players in McKinley High School is k = 7
The number of rounds is n = 4
The highest number of match each player can play is w = 1
Generally the total number of schedules is
