A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 49.0 and 54.0 minutes. Find the probability that a given class period runs between 50.75 and 51.75 minutes.
Find the probability of selecting a class that runs between and minutes.
Answer: 0.050
I just did it and I got it right.
The probability of selecting a class that runs between 51.0 and 52.5 minutes is 0.3 or 30%.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
Since the lengths of the classes are uniformly distributed between 49.0 and 54.0 minutes, the probability of a class running between any two values within this range is proportional to the length of the interval between these two values.
The total length of the possible class periods is:
54.0 minutes - 49.0 minutes
= 5.0 minutes
So, the probability of a randomly selected class running between 50.75 and 51.75 minutes can be calculated as follows:
Length of the interval
= 51.75 minutes - 50.75 minutes
= 1.0 minute
Probability = (Length of the interval) / (Total length of possible class periods)
Probability = 1.0 minute / 5.0 minutes
Probability = 0.2
Therefore, the probability of a given class period running between 50.75 and 51.75 minutes is 0.2 or 20%.
Similarly, the probability of selecting a class that runs between a and b minutes, where a and b are between 49.0 and 54.0 minutes and a < b, is given by:
Probability = (Length of the interval between a and b) / (Total length of possible class periods)
Probability = (b - a) / 5.0
For example, if we want to the probability of selecting a class that runs between 51.0 and 52.5 minutes, we would have:
Probability = (52.5 - 51.0) / 5.0
Probability = 0.3 or 30%
Thus,
The probability of selecting a class that runs between 51.0 and 52.5 minutes is 0.3 or 30%.

A line intersects the points
(-2,9) and (3, -11).
What is the slope of the line in
simplest form?
m = [?]
[tex]\\[/tex]Answer:
m = - 4
Step-by-step explanation:
Slope Formula: [tex]m=\frac{y_{2}- y_{1} }{x_{2}- x_{1} }[/tex]
Substitute (-2,9) and (3,-11) into m = [tex]\frac{y_{2} -y_{1} }{x_{2} x_{1} }[/tex]
= [tex]m=\frac{-11-9}{3-(-2)}[/tex]
m = -4
Answer:
Slope (m) = -4
Step-by-step explanation:
Given :-
Points (-2, 9) and (3, -11)
To Find :-
Slope (m)
Solving :-
m = y₂ - y₁ / x₂ - x₁
= -11 - 9 / 3 + 2
= -20 / 5
= -4
Solution :-
Slope (m) = -4

A cheetah typically runs 15 miles in 1/5 hours. How fast does a cheetah runs in miles/hour
Answer:
75 miles/hour
Step-by-step explanation:
Cheetahs run 15 miles in 1/5 hours. To get it to be a full hour, you multiply 1/5 by 5. You will also have to multiply 15 by 5 to get the number of miles per hour, and you get 75. Cheetahs can run 75 miles in 1 hour.
Answer:
75 miles per hour
Step-by-step explanation:
ok wooo first question answered so don't trust me too much
so basically we need to find how many miles he runs in one hour and we have 1/5
