What percentage of all the races are ties?
If someone wins the race today, is it more likely for A to win or B to win? How much more likely?
Answers
Answer:
Its a long answer.........
Let makes the table neater. event D= 100m, even E=800m
(Event D) (Event E)
A won the race (Event A) 30 50
B won the race (Event B) 60 25
A and B tied (Event T) 10 25
B did not win the race today. What length of the race was it more likely to have been? The question is asking in what event did the chance of B did not win(lose + ties) is more likely. Then, you need to determine the chance for B did not win in both race.
Chance of B did not win 100-m= 30+10/10=40%
Chance of B did not win 800-m= 50+25/10=75%
The difference would be 75%-40%=35% more likely to lose 800-m race
________________________________
1. What percentage of all the races are ties?
IfThe chance for the race become tie is 10% for 100m and 25% for 800m. Assuming that the 200 race is divided equally, then there would be 100 race of 100-m and 100 race of 800-m.
The number of the event of ties would be:
(100*10% + 100*25%)/ 200= 35/200= 17.5%
__________________________________
2. If someone wins the race today, is it more likely for A to win or B to win? How much more likely?The event should be independent because the two events should not influence each other. That means the probability will not change and no one becomes more likely to win the next race.

What is an equation of the line that passes through the points (6, 5) and (6, -7)?
Answers
Answer:
If a line is parallel to another line they’ll have the same slope. We can figure out the slope by taking the given equation of a line and changing it to slope-intercept formula.
x + 3y = 15
3y = -x + 15
y = -1/3 x + 5
Now we know the slope of our line is -1/3. We can use this and the given point to calculate our y-intercept, commonly known as b in the slope-intercept formula.
-5 = -1/3 (-6) + b
-5 = 2 + b
-7 = b
Now that we know our slope, m, and our y-intercept, b, we can write the equation of the line.
y = mx + b
y = -1/3 x - 7

5x + 15 = 55
5x = 40
x = 8
Correct Answer: B, 40
Hope this helps!
Answer:
x = 8
Step-by-step explanation:
Reorder the terms:
15 + 5x = 55
Solving
15 + 5x = 55
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15' to each side of the equation.
15 + -15 + 5x = 55 + -15
Combine like terms: 15 + -15 = 0
0 + 5x = 55 + -15
5x = 55 + -15
Combine like terms: 55 + -15 = 40
5x = 40
Divide each side by '5'.
x = 8

x = (2y + 1) / (y - 1)x(y - 1) = 2y + 1xy - x = 2y + 1xy - 2y = x + 1y(x - 2) = x + 1y = (x + 1) / (x - 2)Substitute y with f⁻¹(x):

Trains Two trains, Train A and Train B, weigh a total of 265 tons. Train A is heavier than Train B. The
difference of their weights is 239 tons. What is the weight of each train?
Answers
Answer:
Train A weighs 252 tons and Train B weighs 13 tons
Step-by-step explanation:
Let "A" represent the weight of Train A and "B" represent the weight of train B.
We can use this to set up a system of equations:
A+B=265
A-B=239
We can solve using elimination. Let's subtract the second equation from the first to cancel out A.
2B=26
Divide both sides by 2
B=13
Plug 63 back in for B in any of the two equations:
A+13=265
Subtract 13 from both sides
A=252
Train A weighs 252 tons and Train B weighs 13 tons
