Answer:
Step-by-step explanation:
<u>Slope- intercept form:</u>
<u>Given</u>
- m = -38 and point (0, 10)
As per given point, y-intercept is b = 10
<u>So the equation is:</u>
Using the expected value, it is found that you should charge $4 to have a fair game.
------------------------
- A probability is the <u>number of desired outcomes divided by the number of total outcomes</u>.
- The expected value is the <u>sum of each outcome multiplied by it's respective probability</u>.
- When you roll two dice, there are possible outcomes.
- We suppose a cost of x.
- In 6 of them, the sum is 7: (1,6), (2,5), (3,4), (4,3), (5,2) and (6,1).
- Thus, probability of earning a profit of 12 - x.
- 2 of them have sums of 2 or 12, which are (1,1) and (6,6).
- Then, probability of earning a profit of 36 - x.
- If the outcome is any of the remaining 28, the player loses, thus probability of losing x.
- The game is fair if the <u>expected value is 0</u>, then:
A value of $4 should be charged.

the answer is x^2+2x-24
steps-
(x+6)(x-4); x(x)+x(-4) 6(x)+6(-4)
(x^2-4x)+(6x-24)
x^2+2x-24
Answer: x = -1
Step-by-step explanation:
You are trying to figure out what the missing number is that will make 4
so we know that only 2 plus or multiplied by 2 can = 4
and because 2 is outside the parentheses it has to be multiplication meaning that x + 3 has to equal 2
4 = 2(x+3)
4 = 2 ( -1 + 3)
4 = 2 (2)
2 * 2 =4
4 = 4
First find the GCF
THis is wx^3y^2
so factoring we have
wx^3y^2( w^4 - y^3)
