10 = 38mn – 33mn
10 = 5mn
10/5 = mn
2 = mn
Therefore,
= –3/2(2)
= –6/2
= – 3
Answer:
The answer is no
Step-by-step explanation:
because if you substitute q for 5 and you do 52 divided by 5 you will get 10.4 not 13 so the answer is no it is not a solution.
If all the marbles are identical then order does not matter so you use combination.
nCr so 10C4 = n! / (n-r)!(r!)
The expected value of the game is the mean value of the game
The expected value of the game is $1
<h3>How to determine the expected value?</h3>
There are 13 spades in a deck of card of 52
So, the probability of selecting a spade is:
P(Spade) = 13/52
Simplify
P(Spade) = 1/4
Winning = $7
The probability of not selecting a spade is:
P(Not spade) = 1 - 1/4
Simplify
P(Not spade) = 3/4
Lose = $1
The expected value of the game is:
This gives
Simplify
Evaluate
Hence, the expected value of the game is $1

Answer: answer 40.
Step-by-step explanation:
Note : lets make x the missing denominator.
I would take the 4/5 and set it equals to 32/x
we then cross multiply
where it would be 4 * x = 32 * 5
it would then be 4x = 160
we would then divide 160 by 4
x = 160/ 4
and x would be 40
.... therefore the missing denominator is 40.
