Answer:
5 1/7 or 36/7
Step-by-step explanation:
11 8/7+3 5/1-x=15
12 1/7+8-x=15
12 1/7+8-15=x
20 1/7-15=x
5 1/7=x
If the answer your looking for is a graph then yeah
Answer:
The spinner has 6 equal-sized slices, so each slice has a 1/6 probability of showing up.
I guess that we want to find the expected value in one spin:
number 1: wins $1
number 2: wins $3
number 3: wins $5
number 4: wins $7
number 5: losses $8
number 6: loses $8
The expected value can be calculated as:
Ev = ∑xₙpₙ
where xₙ is the event and pₙ is the probability.
We know that the probability for all the events is 1/6, so we have:
Ev = ($1 + $3 + $5 + $7 - $8 - $8)*(1/6) = $0
So the expected value of this game is $0, wich implies that is a fair game.

Answer:</h3>
a=45

Solution:</h3>
- We need to multiply both sides by 3 in order to get rid of the denominator, 3:
- 2/3a•3=30•3
- 2a=90
- Divide both sides by 2:
- a=45

Answer:
m = y1 - y2/ x1 -x2
Step-by-step explanation:
Your coordinates are (4, 1) and (0, -3) so m (slope) equals 1 - (-3) over 4 - 0 = 4/4 = 1
Hope this helped!
