x + x + 3 + x - 8
3x - 5 = 55
3x = 60, x = 20
Since we put Julie as x, we put Janet at x + 3, and the brother is x - 8 (8 years younger)
Julie is 20
Janet (x + 3) = (20 + 3) = 23
Brother(x - 8) = (20 - 8) = 12
Answer:
pretty boring, I'm kind of tired to be honest. What ab you?
thanks for the points though
It is asking you for the equivalent percentage or fraction. So, where it says 1/2, it wants the percentage, which is 50%. Where it says .25, it wants the fraction, which is 1/4....
<u>Given</u>:
Given that in a game a player draws and replaces a card from a deck 2 times.
The possible outcomes and payouts are given.
We need to determine the expected value for someone playing the game.
<u>Expected value:</u>
The expected value for someone playing the game can be determined by
Simplifying the values, we have;
Dividing the terms, we get;
Adding, we have;
Thus, the expected value for someone playing the game is $8
First method:
What we can do first is to distribute directly 4.2 to 6 and
0.43, that is:
4.2 (6 + 0.43)
= 4.2 * 6 + 4.2 * 0.43
= 25.2 + 1.806
= 27.006
Second method:
We can add the two numbers 6 and 0.43 then multiply with
4.2, that is:
4.2 (6 + 0.43)
= 4.2 (6.43)
= 27.006
What we see is the Distributive Property of multiplication
which states that multiplying the sum of a number is similar to multiplying
each number and then adding the products.
