The probability that it is a female with long hair is 0.75 .
Potential is described by probability. This branch of mathematics deals with the occurrence of a random event. The value's range is 0 to 1. Probability generally refers to the degree to which something is likely to occur. Gonna determine how likely something is to occur, use probability. Many things are hard to predict with 100% certainty. We can only anticipate the possibility of an event occurring using it, or how likely it is. In the probability scale, 0 indicates an impossibility and 1 indicates a certainty. Every event's probability in a sample space is one.
the likelihood of an occurrence, E is
P(E) = The proportion of positive outcomes to all outcomes.
In probability, an event is said to be independent if it is completely unaffected by the occurrence of any other event, and it is considered to be dependent if it is affected by other occurrences.
Using the literature and formulas mentioned above, we have:
Let F stand for the circumstance that the student is a female and L for the circumstance that the student has long hair.
In this illustration, the probability are as follows:
P(F) = 0.60; P(L) = 0.50
P(F AND L) = 0.45 and P(L|F) = 0.75 as a result.
As a result, there is a 0.75 percent chance that a randomly chosen student has long hair.

Clay is flying a helicopter at an altitude of 400 feet in the air. Jason is diving 200 feet below the surface.
How far apart are Clay and Jason?
Explain how to show the distance between Clay and Jason using absolute value.
Clay and Jason are 600 feet far apart.
When an object goes above the surface, the altitude is measured as +ve and when an object goes below the surface, the altitude is measured as -ve.
Since Clay is flying a helicopter at an altitude of 400 feet in the air,
The Value of altitude of Clay = +400
Since, Jason is diving 200 feet below the surface,
The Value of altitude of Jason = -200
The the distance between Clay and Jason = (The Value of altitude of Clay) - (The Value of altitude of Jason)
= +400 - (-200)
= 400 + 200
= 600 feet
Therefore, the distance between Clay and Jason is 600 feet.

An airplane travels 130,000 feet horizontally drring take-off, reaching a height of 35,000 feet. the airplane travels at a constant rate.what is the plane's launch angel? round your answer to the neatest degree.
The launching angle of the plane which has reached a height of 35000 ft is 15°
Let the distance travelled by the airplane horizontally be AB
The height reached by the airplane be BC
Thus AB = 130000 ft
BC = 35000 ft
The launching angle of the airplane can be found using the formula
tanθ = opposite / adjacent
(or)
tanθ = BC / AB
Let us substitute the known values in the above equation, we get
tanθ = 35000/130000
tanθ = 0.2692
θ = tan⁻¹ (0.2692)
θ = 15.067°

The exponential function that shows the amount of money paid for membership x months after the beginning of the year is given by y = 32(1.18)ˣ.
What are the types of exponential function?There are two possibilities for the exponential function: it can be increasing or decreasing. Being increasing means that as the value of x increases, the value of f(x) also increases; being decreasing means that as the value of x decreases, the value of f(x) also decreases.
Let y represent the amount of money paid for membership x months after the beginning of the year. Abby's gym membership will increase by 18% a month. This is an exponential function.She is currently paying $32 a month, hence:y = 32(1 + 0.18)ˣy = 32(1.18)ˣ

Hi, I am taking PSAT and I am working on the math section. I need help with answering this math type of question. Please give the best explanation.
By using the concept of uniform rectilinear motion, the distance surplus of the average race car is equal to 3 / 4 miles. (Right choice: A)
How many more distance does the average race car travels than the average consumer car?
In accordance with the statement, both the average consumer car and the average race car travel at constant speed (v), in miles per hour. The distance traveled by the vehicle (s), in miles, is equal to the product of the speed and time (t), in hours. The distance surplus (s'), in miles, done by the average race car is determined by the following expression:
s' = (v' - v) · t
Where:
v' - Speed of the average race car, in miles per hour.v - Speed of the average consumer car, in miles per hour.t - Time, in hours.Please notice that a hour equal 3600 seconds. If we know that v' = 210 mi / h, v = 120 mi / h and t = 30 / 3600 h, then the distance surplus of the average race car is:
s' = (210 - 120) · (30 / 3600)
s' = 3 / 4 mi
The distance surplus of the average race car is equal to 3 / 4 miles.

The inequality expression given as |-4/3x - 5| > 19 has a solution of 10.5 < x < -18
How to solve the inequality?From the question, the inequality is given as
|-4/3x-5|>19
Rewrite properly as
|-4/3x - 5| > 19
Remove the absolute bracket
So, we have the following representation
-19 > -4/3x - 5 > 19
Add 5 to all sides of the inequality
So, we have
-14 > -4/3x > 24

The value of t for the angles of the given triangle will be 30.67.
What are the angles of triangle?The straight angle is equal to the total of the angles of a triangle. Three angles, one at each vertex and bounded by two neighbouring sides, make up a triangle. For a very long period, it was unknown if there were any alternative geometries for which the total is different.
The triangle has three sides and is a two-dimensional figure having the sum of the angles of 180 degrees.
In the given image the three angles are 2t, t + 8, and t - 12. The value of t will be calculated as:-
2t + t + 8 + t - 12 = 180
