In a particular college class, 60% of the students are female. Of the female students, 75% have long hair. One student is picked randomly in the class. What is the probability that it is a female with long.

Answers

Answer 1

The probability that it is a female with long hair is 0.75 .

How is probability defined and what is it?

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.

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

4t - 4 = 180

4t = 184

t = 184 / 4

t = 30.67

Therefore, the value of t for the angles of the given triangle will be 30.67.

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

How to find the zeros of the quadratic equation?

I'm only solving the first question, as it is how the guidelines say.

Here we have the quadratic equation:

x^2 + 7x = 8x + 12

First, we can rewrite this equation as:

x^2 + 7x - 8x - 12 = 0

x^2 - x - 12 = 0.

Using Quadratic formula we can see that the solutions (or zeros of the quadratic) are:

x = (1 ± √(  (-1)^2 - 4*1*-12))/(2*1)

x = (1 ± 7)/2

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

Answers

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°

Answers

Based on the fact that the two numbers multiply to 2,400 and add up to -16, the numbers are undefined.

How to find the numbers?

Assume that one of the numbers is x and the other number is y, the system of equations to represent this is given that the two numbers add up to -16 and multiplying to 2,400:
x + y = -16

xy = 2,400

Expressing y in terms of x :

xy = 2,400

y = 2,400 / x

Solving for x gives:

x + y = -16

x + (2,400 / x) = -16

x = 0

y = 0
