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 child learns new words very quickly, but their vocabulary grows slower as they grow up. There is no upper-limit to the size of a person's vocabulary, so a logarithmic growth model is reasonable. The number of words can be related to the child's age (in months) according to the following formula: W(m)=10,000 ⋅ log(m) − 13,000
where m is the number of months in a person's age.
How many vocabulary words would a person have after 20 years (240 months) ?
A. 10.3

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
so multiply 15 by 5
75

3y - 15 = -21
What is y?
Answer:
y= -2
Step-by-step explanation:
3y -15 =-21
add 15 to both sides
-15+ 15 =0 , -21+ 15 = -6
so we have
3y= -6
isolate y by dividing by 3 to each side and get
y=-2

The Wares want to buy a new computer. The regular price is $1049.the store is offering 20% discount and a sales tax of 5.25% is added after the discount .what is the total cost?
Answer:
$883.26
Step-by-step explanation:
Multiply the regular price ($1,049) by the Percent Discount (20%). To do this, multiply 1,049 by 0.2 :
1,049(0.2)=$209.8
After multiplying, you get the amount taken off by the discount. So you subtract the amount you got ($209.8) from the original amount ($1049) :
$1049-$209.8=$839.2
Now that you've calculated the discount price, you can calculate the sales tax. Make sure you do this part second, because it says to do so in the problem.
To calculate the sales tax, you do the same as above. Multiply your NEW cost ($839.2) by the sales tax (5.25%). The equation is:
$839.2(5.25%)=$44.058
Round $44.058 to $44.06. Since this is a Sales Tax, you add this on to your previous amount of $839.2
$839.2+$44.06=$883.26
The final cost of the computer is $883.26

Write an expression for the perimeter of the triangle shown below:
(linked)

B: 10x − 39
C: 5.5x − 9
D: 5.5x + 9
I don't normally ask questions so ill just give 100 points to who can answer this
Solution:
The perimeter of the triangle is basically the sum of its sides.
[tex]\rightarrow P = (0.3x + 24) + (5x) + (0.2x - 15)[/tex]
Open the parenthesis:
[tex]\rightarrow P = 0.3x + 24 + 5x + 0.2x - 15[/tex]
Combine like terms:
[tex]\rightarrow P = x(0.3 + 0.2 + 5) + (24 - 15)[/tex]
Simplify the equation:
[tex]\rightarrow P = x(5.5) + (9)[/tex]
Further simplify:
[tex]\rightarrow P = 5.5x + 9[/tex]
Option D is correct.
Perimeter=Sum of three sides
Perimeter:-
[tex]\\ \rm\Rrightarrow 0.3x+24+5x+0.2x-15[/tex]

[tex]\\ \rm\Rrightarrow 5.5x+9[/tex]
Find the EXACT circumference if the area is 196π square feet. Unit of measurement is feet or ft
Answer:
87.9645943005 feet
Step-by-step explanation:
The formula for the area of a circle is pi x radius to the power of 2. What number to the power of 2 is 196? 14.
So, the radius is 14.
The formula for the circumference of a circle is pi x diameter. If the radius is 14, the diameter is 28.
28 x pi = 87.9645943005
