The probability of F P(F) = 0.33 and the conditional probability of F given G P(F|G) = 0.24. F and G is associated since they are not independent.

Conditional probability is known as the possibility of an event or outcome happening, based on the existence of a previous event or outcome. The conditional probability P(A|B) occur only in the case of dependent events. It gives the conditional probability of A given that B has occurred.

P(F|G) = P(F∩G) / P(G)

P(F∩G) = Probability of happening of both F and G

P(F) = 199/600 = 0.3317

P(F∩G) = 79/600 = 0.1317

P(G) = 330/600 = 0.55

P(F|G) = 0.1317/0.55

P(F|G) = 0.2394.

Two events say A and B are independent if the probability of occurrence of one of them is not affected by the occurrence of the other, mathematical expressed as P(A ∩ B) = P(A) × P(B)

P(F) × P(G) = 0.3317 × 0.55

P(F) × P(G) = 0.1824

P(F∩G) is not equal to P(F) × P(G) from the data given.

Therefore, the probability of F P(F) = 0.33 and the conditional probability of F given G P(F|G) = 0.24. F and G is associated since they are not independent.

In addition to being novel, arbitrary matrices with complicated elements are viewed as having potential. It is based on I. Schur's theorem, which states that any complex matrix is valid.

Any number of entries may be present in an arbitrary matrix. [a,b] [c,d] would be a random 2x2 matrix. Where all of the elements of some set (a, b, c, and d) (usually the real numbers.)

Step-by-step explanation:

Answer: a) The equation to represent the cost of the car suggested by the son is:

C1 = 250 + 0.22k

where C1 represents the total cost of renting the car, and k represents the number of kilometers driven.

b) The equation to represent the cost of the car suggested by the daughter is:

C2 = 96 + 0.5k

where C2 represents the total cost of renting the car, and k represents the number of kilometers driven.

c) To find when the two cars cost the same, we need to solve the equation:

C1 = C2

Substituting the expressions for C1 and C2 from parts a and b, we get:

250 + 0.22k = 96 + 0.5k

Simplifying this equation, we get:

0.28k = 154

Dividing both sides by 0.28, we get:

k = 550

Therefore, the two cars cost the same when the number of kilometers driven is 550.

d) If the Clarke's plan to drive 500km, we can calculate the total cost for each car by substituting k=500 into the equations from parts a and b:

C1 = 250 + 0.22(500) = 360

C2 = 96 + 0.5(500) = 346

Therefore, the car suggested by the daughter is less expensive for a 500km trip, as it would cost $346 compared to $360 for the car suggested by the son.

$68/10 is better to buy as price of one ticket will be $6.8 which is less than that of $7.5 for other ticket.

The appraisal of a single item or part within one group is known as unit value.

So,

$68/10 tickets = 68/10

$68/10 tickets = $6.8 for each ticket.

Now,

$15/2 tickets = 15/2

$15/2 tickets = $7.5 for each ticket.

Thus, $68/10 is better to buy as price of one ticket will be $6.8 which is less than that of $7.5 for other ticket.

As a result, there are 1140 different methods to select a committee of three from a group of 20 people.

The study of random occurrences or phenomena falls under the category of probability, which is a branch of mathematics. It is a way to gauge how likely something is to happen. Probability is expressed as a number between 0 and 1, with 0 denoting that the occurrence won't happen and 1 denoting that it will definitely happen. By dividing the number of favourable outcomes by the total number of possible outcomes, one can determine the probability of an occurrence. Numerous disciplines, including statistics, finance, engineering, and science, use probability extensively to forecast the chance of an event happening and base decisions on that forecast.

The following combination formula determines how many options there are to select a committee of three from a class of 20 members:

c² = 225

c = √225 = 15

Answer: 15 ft

Answer:

15 feet

Step-by-step explanation:
So, to start we have to find the area of the wall.
9(12)=108
Now, we need to find half of the walls area
108/2=54

We have our length and height, but we need to find the hypotenuse using Pythagoreans theorem.
9 is our A and 12 is our B
a^2+b^2=c^2
81+144=c^2
c^2=225
The square root of 225 is 15.
C=15

Therefore, the stripe will be 15 feet.

Answer:

When two proper fractions are multiplied together, the product will be smaller than both factors.

Step-by-step explanation:

To understand why this is true, we can consider the concept of fractions as parts of a whole. When we multiply two proper fractions, we are essentially taking a part of a part, which results in a smaller portion overall.For example, if we multiply 1/2 by 2/3, we are taking half of something and then taking two-thirds of that half. The result is 1/3, which is smaller than both 1/2 and 2/3.Therefore, the correct answer is: The product will be smaller than both factors.

Answer:The product will be smaller than both factors.

When two proper fractions are multiplied together The product will be smaller than both factors.Take a look at the equation below.

¾ * ⅔=  3 times 2 is 6 and 4 times 3 is 12. So the equation is 6/12 .

6/12 is simplified to 1/2. 1/2 is less than both 2/3 and 3/4. Which means the product is smaller. Hence, the correct answer is the product will be smaller than both factors.

Answer:

Step-by-step explanation:

The value of cos^-1(-sqrt(3)/2) is -π/6 or -30 degrees.

We know that cos^-1(x) gives the angle whose cosine is x, in the range [0, π]. In this case, we are looking for the angle whose cosine is -sqrt(3)/2.

Recall that the cosine function is negative in the second and third quadrants of the unit circle. In the second quadrant, the reference angle whose cosine is sqrt(3)/2 is π/6 or 30 degrees, but the cosine function is negative in this quadrant. Therefore, the angle whose cosine is -sqrt(3)/2 is -π/6 or -30 degrees, which is in the fourth quadrant.

So, cos^-1(-sqrt(3)/2) = -π/6 or -30 degrees.

It should be noted that AP'Q'R' a 180° rotation about the origin of APQR.

It should be noted that to perform a 180° rotation about the origin, one has to draw the original figure and label its coordinates and draw the origin and label it O.

One can also use the following formula to find the coordinates of the image of a point (x,y) after a 180° rotation about the origin:

(x', y') = (-x, -y)

Here, P'Q'R' represents the coordinates of the image of the point PQR. We simply take the negative of the original x and y coordinates to find the new coordinates after the rotation.

By answering the above question, we may state that The range of -3 x 2 inequality is the answer to the compound inequality.

A connection between two expressions or values that is not equal in mathematics is referred to as an inequality. Hence, inequity results from imbalance. In mathematics, an inequality establishes the connection between two non-equal numbers. Egality and inequality are not the same. Use the not equal symbol most frequently when two values are not equal (). Values of any size can be contrasted using a variety of inequalities. By changing the two sides until just the variables are left, many straightforward inequalities may be solved. Nonetheless, a variety of factors support inequality: Both sides' negative values are split or added. Exchange the left and the right.

We must first remove 6 from each of the three elements of the compound inequality -6 4x + 6 14 in order to arrive at the following result:

-6 - 6 ≤ 4x < 14 - 6

If we simplify, we get:

-12 ≤ 4x < 8

Then, we divide each of the three inequality components by 4, keeping in mind that we don't need to reverse the inequality's signs because 4 is positive, to arrive at:

-3 ≤ x < 2

The value of y, given that Triangle FEG is similar to Triangle IHJ is 10.

Seeing as Triangle FEG is similar to Triangle IHJ, we can assume that angle EGF is the same as angle HJ1.

This means that 5 y + 8 is equal to 58 degrees.

The value of y is therefore :

5 y + 8 = 58

The length of the side of the square would be 12 inches.

A square is a two-dimensional plane object in geometry that has four equal sides and four equal but 90° angles. The characteristics of a rectangle and a square are somewhat similar, although a rectangle only has its opposite sides equal. As a result, a rectangle is only referred to as a square if its four sides are of the same length.

Given : side of the triangle = 16 inches

So, the perimeter of the triangle = 16+16+16

                                                      = 48 inches

Now, the wire is unbent and shaped into a square.

So, the length of the wire would be same.
