95x=85x+288
You could add 288 to any side, it just shows that they're 288 miles apart.
Let's subtract 85x from both sides.
10x=288
28.8=x
It'll take 28.8 hours for the trains to meet. Let's make sure.
28.8×95
2,736
28.8×85
2,448
2,736-2,448
288
So, they'll meet up after 28.8 miles.
If p then q. P, therefore q.
2.5 week 3 days = 20 days and 12 hours
2.5•7=17.5 17.5 +3 = 20.5
5 week 3 days = 38 days
5•7=35 35+3= 38 days
Construct a probability mass function (pmf) for x, the dollar amount won by a contestant in this game is 1/18.
What is a probability math example?
- Probability is the measurement of how likely something is to happen.
- As an example, since there is only one way to get a head and a total of two possible results, the likelihood of flipping a coin and getting heads is one in two. a tail or a head.
- We write P(heads) = 12 here. The four most popular approaches to probability are axiomatic, classical, empirical, and subjective.
from above total number of chips =4+6+5+2+1 =18
hence Probabilty of win 0 P(0)=4/18
P(1) =6/18
P(5) =5/18
P(10) =2/18
P(100)=1/18
x P(x) xP(x)
0 0.22 0.00
1 0.33 0.33
5 0.28 1.39
10 0.11 1.11
100 0.06 5.56
8.39
therefore expeted value =8.39

Answer:
x = 14 is an extraneous solution
Step-by-step explanation:
Divide both sides by 4.
Square both sides.
Since we squared both sides, we much check for extraneous solutions because the process of squaring both sides can introduce extraneous solutions.
Check x = 14:
16 = -16 is a false statement, so the solution we found, x = 14, is an extraneous solution.
