The probability that we did not see all three colors is [tex]$\frac{13}{16}[/tex]

Consider the event,

A: Did not see all 3 colors

Complement of the event A is A’ where

A' : All colors were seen

Since 3 balls are drawn and all colors should be seen, it implies that there is 1 ball of each color

It is required to find P(A) = P(did not see all colors)

By the probability rule for complement:

P(A)  =1-P(A')

P(A') & =P(all colors were seen )

=P(1 White AND 1 Green AND 1 Red )

Total number of balls = 4

Number of combinations of 3 balls possible = 64

Since drawing a ball is with replacement, we have the following number of combinations with each color represented where R1 and R2 are the two red balls.

The table attached at end of the solution

Total number of combinations with each color represented = 12

Thus the probability of A’ is:

[tex]$P\left(A^{\prime}\right) & =\frac{12}{64} \\[/tex]

[tex]$P(A) & =1-\frac{12}{64} \\[/tex]

What is a polynomial?

A polynomial is a mathematical statement made up of coefficients and indeterminates that uses only the operations addition, subtraction, multiplication, and powers of positive integers of the variables.

We can now look into each polynomial.

a) x³ + 125

   125 is a cube of 5 and also  x³  is the power of x.

So this is a perfect cube.

b) 8p³ - 27

    8p³ is a perfect cube of 2p and 27 is a perfect cube of 3.

So it is a perfect cube.

c) 12x³-9

    This is neither a cube nor a square.

d) a²-100

Alternate interior angles are the angles formed by the intersection of a transversal line with two parallel lines on the plane.

Alternate interior angles are formed on the inner side of the two parallel lines but are on the opposite side of the transversal line.

From the given figure, we have two parallel lines and two transversal lines and thus we can find alternate interior angles.

Alternate interior angles are always equal.

Angles formed by 2x° + 56° and the angle 134° are alternate interior angles and are thus equal.

The linear equations for the two companies are:

Company 1: y = 1.5*x + 5.5

Company 2: y = 0.5*x + 6

So the rate of company 1 is trice the rate of company 2.

When we have constant rates, then we have linear relations that can be written as:

y = m*x + b

Where m is the constant rate and b is the y-intercept.

And if we have two points (x₁, y₁) and (x₂, y₂), then the constant rate is:

m = (y₂ - y₁)/(x₂ - x₁)

So for the first table we can use the pairs:

(2.5, 9.25)

(6, 14.5)

So the rate is:

m = (14.5 - 9.25)/(6 - 2.5) = 1.5

Then the line is:

y = 1.5*x + b

To find the value of b, we can replace the values of one of the points, like (2.5, 9.25), we will get:

9.25 = 1.5*2.5 + b

9.25 - 1.5*2.5 = b

5.5 = b

And for company 2 we can try to identify two points on the graph, these can be (0, 6) and (1, 6.50), so the rate is:

m' = (6.50 - 6)/(1 - 0) = 0.50

So the rate of company 1 is 3 times the one of company 2,  And the y-intercept is y = 6.

So the equations are:

Company 1: y = 1.5*x + 5.5

Company 2: y = 0.5*x + 6

So the rate of company 1 is trice the rate of company 2.

The two points that represent the solution of the inequality graph are (-1,0) and (0,2).

The function of an inequality graph obeys the linear slope intercept form y= mx + b, but the distinction here is that the equal to sign (=) is represented with >, <, ≥, and ≤, as the case may be. So, we use, > and < when the line is dotted or dashed and  ≥, and ≤, when we have a solid line on the graph.

So, using the two points on the (-1,0) and (0,2), the slope of the graph is 2, and the y-intercept is also 2.

The linear representation of the graph is: y = 2x + 2, in its inequality form, sInce the graph is increasing from the left to the right and the line is solid; we have:

y  ≥ 2x + 2

Therefore, we can conclude that the function of the graph is y  ≥ 2x + 2 and the two points that represent the solution of the inequality graph are (-1,0) and (0,2).

The probability that player a wins is approximately 0.189 or 18.9%.

The probability of Player A winning can be calculated by adding the probability of both players rolling different values and Player A getting a higher value, as well as the probability of both players rolling the same value (in which case Player A wins by default).

To calculate the probability of both players rolling different values and Player A getting a higher value, we can calculate the probability of each possible combination of rolls and sum them up. There are a total of 50 * 40 = 2000 possible combinations of rolls. Out of these, 50 of them result in Player A rolling the highest value, and 400 result in Player B rolling the highest value. Therefore, the probability of Player A winning in this scenario is 50 / (50 + 400) = 50 / 450 = 1/9.

The probability of both players rolling the same value can be calculated as the minimum of the number of sides of the two dice, which is 40, divided by the maximum number of sides, which is 50. Therefore, the probability of both players rolling the same value is 40/50 = 8/10.

Finally, the overall probability of Player A winning can be calculated as the sum of the above two probabilities:

P(Player A wins) = P(different values and Player A higher) + P(same values)

= 1/9 + 8/10

= 17/90

The variance of head circumferences of adult males is 1.

Variance is a measure of how data points differ from the mean. According to Layman, a variance is a measure of how far a set of data are spread out from their mean value.

Variance means to find the expected difference of deviation from actual value. Therefore, variance depends on the standard deviation of the given data set.

The more the value of variance, the data is more scattered from its mean and if the value of variance is low or minimum, then it is less scattered from mean. Therefore, it is called a measure of spread of data from mean.

Let x be the head circumferences of some males.

rAnswer: x-intercept: (-0.75, 0)

y-intercept: (0, 3/7)

Step-by-step explanation: An x and y intercept is the point when the line crosses the x and y axis respectively. When a line crosses the x axis, the y value is 0 and when the line crosses y axis, the x value is 0. This means   we can set y and x equal to 0 and solve for the other variable.

To solve for the x intercept, we set y equal 0 so:

-4x + 7(0) = 3

-4x = 3

x = -(3/4)

so we get

(-3/4, 0) or (-0.75, 0) for our x int

For the y intercept we set x equal 0:

-4(0) + 7y = 3

7y = 3

y = 3/7

The Three options are

1.  m∠5 + m∠6 = 180°

2. m∠2+ m∠3 = m∠6.

3. m∠2 + m∠3 + m∠5 = 180°.

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

Consider ΔABC with Exterior angles as

∠ 1, ∠ 4 , and ∠ 6

Exterior angle Property of Triangle:

A triangle's exterior angle is equal to the sum of its inner angles on either side.

For Exterior ∠ 1 we have

m∠1 = m∠ 5 + m∠ 3

Similarly,

For Exterior ∠4 we have

∠ 4 = ∠ 5 + ∠ 2.

Similarly,

For Exterior ∠ 6 we have

∠ 6 = ∠ 2 + ∠ 3.

Triangle Sum Property:

The total of all the angles of a triangle equals 180°.

∴ m∠2 + m∠3 + m∠5 = 180°

Linear Pair:

A linear pair of angles must add up to 180 degrees since a straight angle has a measure of 180 degrees.

∴ m∠5 + m∠6 = 180°
