Answer:
Choice D
Step-by-step explanation:
probability of B given A
given you win the first race, you win the second race
Answer: The correct option is
(D) The probability that you win the second race given that you win the first race.
Step-by-step explanation: We are given the following two events :
A : You win the first race
B : You win the second race.
We are given to select the statement that represents P(B\A).
We know that
for any two events R and Q, the probability P(Q\R) represents the probability of happening of event Q given that the event R has already happened.
Therefore, for the given two events A and B,
the probability P(B\A) represents the probability that you win the second race given that you win the first race.
Thus, (D) is the correct option.
Answer:
Step-by-step explanation:
12 = 4 × 3
20 = 4 × 5
12 + 20 = 4 × 3 + 4 × 5 = 4 × (3 + 5)

Answer: A
--------------------------------------------------
Explanation: The mean is when you add all the numbers and divide it by how many numbers their are. Since the graph is skewed it's best that we take the mean of the data set instead of the median. The 3 points on the ten point are outliers.

Hope This Helped! Good Luck!
A. Mean, because the data is skewed and there are outliers.
For the unknown number when I subtract 5 from my number, multiply that equality by 4 and then add 7 to the result, I get 35 is 12.
A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Let the unknown number be 'n' if I subtract 5 from my number, multiply that equality by 4, and then add 7 to the result, I get 35.
∴ 4(n - 5) + 7 = 35.
4n - 20 + 7 = 35.
4n = 48.
n = 48/4.
n = 12.

Answer:
Yes
Explanation:
Each piece is 6 inches, and if you do 6*42, it is 252. 252/12 because to change it into feet is 21. 21 is greater than 20.
Answer:
Step-by-step explanation:
The expression that gives the train's speed in miles per hour is:
Speed = 524 / 4.5 = 116.44 miles per hour.
To find the train's speed in miles per hour, you can use the formula:
Speed (in miles per hour) = Distance (in miles) / Time (in hours)
In this case, the distance the train travels is 524 miles, and the time it takes is 4 1/2 hours. To convert 4 1/2 hours into a decimal, you can calculate it as follows:
4 1/2 hours = 4 + 1/2 = 4.5 hours
Now, you can use the formula to calculate the speed:
Speed (in miles per hour) = 524 miles / 4.5 hours
Speed (in miles per hour) = 116.44 miles per hour (rounded to two decimal places)
So, the expression that gives the train's speed in miles per hour is:
Speed = 524 / 4.5 = 116.44 miles per hour
