a) Find P(X < 25), P(X > 15), and P(15 < X < 25)
b) Find the 40th percentile
a) P(X<25) = 0.7135 P(X>15) = 0.4724 P(15<X<25)=0.1859 and The 40th percentile is : 10.2165
What is exponential distribution?The exponential distribution is a continuous probability distribution used in probability theory and statistics that frequently addresses the amount of time until a certain event occurs. It refers to a system in which things proceed continuously and separately at such an average speed that is constant.
Let X = The time (in minutes) that it takes a mechanic to change oil
We have,
X = Exp (mean = 20)
The distribution function of X is: F(x) = P (X < x) = 1 - e{-x/20}
a) Consider, P (X < 25) = F(25)
= 1 - e{-25/20}
= 0.7135
Consider, P( X > 15)
= 1 - P (X < 15)
= 1 - 1 - e{-15/20}
= 0.4724
Consider, P(15 < X < 25)
= P (X < 25) - P (X < 15)
= 1 - e{-25/20} - 1 - e{-15/20}
= 0.1859
Hence,
P(X<25) = 0.7135 P(X>15) = 0.4724 P(15<X<25)=0.1859
b) We want to find x such that P(X<x) =0.40
Consider, P (X < x) = 0.40
1 - e{-x/20} = 0.40
x = 10.2165
Hence, The 40th percentile is : 10.2165

The no. of circular arrangements of n distinct items = (n-1)!
If A,B,C,D,E,F,G and H are the 8 persons to be seated around the table and A,B the 2
particular persons who must not sit together.
The total no.of circular arrangements for 8 persons = (8-1)! = 7! = 5040 --(1)
The no. of circular arrangements possible if A and B were to sit together = 6! (considering A and B as a single pair).
But, A and B can interchange their positions.

A and B are oppoite vertice of a regular ix-ide hape, the point C and D are the midpoint of two oppoite ide. The area of the regular ix-ided hape i 60. Determine the product of the length of the line AB and CD!
The product of AB and CD in a regular hexagon with an area of 60 is (40 / √3) / 2.
To find the product of the length of AB and CD in a regular hexagon, we have to initially calculate the length of one side of the hexagon and later use that information to find the length of AB and CD.
Let us say that the length of one side of the hexagon = s.
W.k.t the area of the hexagon = 60, so we can use the formula for the area of a regular hexagon:
Area = (3 * √3) / 2 * [tex]s^2[/tex]
Making this equal to 60 and solving s:
60 = (3 * √3) / 2 * [tex]s^2[/tex]
120 = 3 * √3 * [tex]s^2[/tex]
40 = √3 * [tex]s^2[/tex]
(40 / √3) = [tex]s^2[/tex]
Taking the square root of both sides:
s = (40 / √3)^(1/2)
Now that we found the length of one side of the hexagon, So we can use that to find the length of AB and CD.
AB = the length of one side of the hexagon times the square root of 3, CD = the length of one side of the hexagon divided by 2.
So,
AB = s * √3
CD = s / 2
Now, we can find the product of AB and CD by multiplying them together:
AB * CD = s * √3 * s / 2
AB * CD = (s^2 * √3) / 2
AB * CD = (40 / √3) / 2
So the product of AB and CD in a regular hexagon with an area of 60 is equal to (40 / √3) / 2.

this was a question on my homework assignment from school but I don't know how to solve this without the height of the cone from top to bottom.
Answer: [tex]\sqrt{585}[/tex] units or [tex]3\sqrt{65}[/tex] units
Step-by-step explanation:
The formula for volume of a cone is π[tex]r^{2}[/tex][tex]\frac{h}{3}[/tex]. You can find the height by plugging in 72π for volume and 3 for radius.
diameter = radius x 2, so 6/2=3 units for radius.
72π = π([tex]3^{2}[/tex])([tex]\frac{h}{3}[/tex])
72=9*[tex]\frac{h}{3}[/tex]
8 = [tex]\frac{h}{3}[/tex]
h = 24 units
The formula for slant height is [tex]\sqrt{{r}^2 + {h}^2 }[/tex]
Plug in 3 for r and 24 for h. You should get [tex]\sqrt{(9+576)}[/tex]=[tex]\sqrt{585}[/tex] or 3[tex]\sqrt{65}[/tex] as your answer.

According to the NCAA, 3. 9% of female high school basketball players go onto play basketball in the NCAA. Of these players, 0. 9% are drafted into the WNBA. If you randomly select one female high school basketball player, what is the probability she will be drafted by a WNBA team?
The probability that a randomly selected female high school basketball player will be drafted by a WNBA team is 0.000351 or approximately 0.04%.
The probability of a female high school basketball player being drafted into the WNBA can be taken as a combination of two probabilities.
The probability that she will play basketball in the NCAA, which is equal to 3.9%, and the probability that she will be drafted into the WNBA given that she plays in the NCAA, which is equal to 0.9%, are both equal.
The probability can be calculated by using the formula:
P(WNBA draft) = P(NCAA) × P(WNBA draft | NCAA)
Where, P(NCAA) = 3.9 ÷ 100 which is equal to 0.039
and, P(WNBA draft | NCAA) = 0.9 ÷ 100 which is equal to 0.009
Hence, by substituting the values in the equation we get
P(WNBA draft) = 0.039 × 0.009
Which is equal to 0.000351 or approximately 0.04%

Question: Which function is best represented by this graph?
Responses: f(x)=x2+2x−1 f(x)=x2−2x−1 f(x)=x2+2x f(x)=x2−2x
The quadratic function best represented by the graph is given as follows:
f(x) = x² + 2x.
How to model the quadratic function?The quadratic function of roots x* and x** is given by the rule presented as follows:
y = a(x - x*)(x - x**).
In which a is the leading coefficient.
The roots are given on the graph by the values of x when the graph crosses the x-axis, hence they are given as follows:
x* = -2, x* = 0.
Hence:
y = a(x + 2)(x)
When x = -1, y = -1, hence the leading coefficient a is obtained as follows:
-1 = a(-1 + 2)(-1)
-a = -1
a = 1.
Meaning that the function is defined as follows:
f(x) = x² + 2x.
