We know that the graph of a polynomial function will intersect the x-axis at its root values, and we know that if the multiplicity of that root is even, the graph will "bounce off"

If the graph crosses the x-axis and appears almost linear at the intercept, it is a single zero.

If the graph touches the x-axis and bounces off of the axis, it is a zero with even multiplicity.

If the graph crosses the x-axis at a zero, it is a zero with odd multiplicity.

The sum of the multiplicities is n.

-0.477  is the value of log 1 by 3 .

A logarithm is defined simply?

The logarithm represents the power to which a number must be raised to obtain another number (see Section 3 of this Math Review for more about exponents).

For instance, since ten raised to the power of two equals 100, the base ten logarithm of 100 is 2: log 100 = 2.

log (1/3)

Asset's expected return;-

The weight of each asset is multiplied by its projected return to determine the expected return. The total predicted return for your portfolio may then be calculated by adding the figures for each investment. Hence, the equation Asset 1 Weight x Expected Return = Expected Portfolio Return Plus (Asset 2 Weight x Expected Return)

The constant variation of Y 8 when X 16 is 2.

What is Direct Proportion?

"When the relationship between two quantities is such that if we increase one, the other will also rise, and if we decrease one, the other quantity will also drop, then the two quantities are in a direct proportion," according to the definition of direct proportion. For instance, suppose there are two numbers, x and y, where x is the number of candies and y is the total amount of money spent. If we purchase more candy, we will be required to pay more, and if we purchase fewer candies, we will be required to pay less. This means that x and y are directly proportional to one another in this situation. The symbol for it is x y. Direct variation is another name for direct proportion.

So,

In the given question, we have:

y as 8 and x as 16;

So,

In order to find the proportional value, we have to divide the x quantity by the y quantity.

So, after dividing we get:

[tex]\frac{X}{Y} = \frac{16}{8}[/tex]

[tex]\frac{X}{Y} = 2[/tex]

So,

The constant proportion will be 2.

Hence,

Joint Distribution of x and y is 25.

Joint Distribution is based on joint probability, which can be simply defined as the probability of two events happening together.

We know the formula for joint distribution

F(x,y) = P(X ≤ x and Y ≤ y) = ∑∑p(xi,yi)

Here x is the number of aces and y is the number of kings in a poker hand.

That means x can take values from 0 to 4 and y can take values from 0 to 4.

∴ F(x,y) = P(X ≤ 4 and Y ≤ 4)

⇒ F(x,y) = p(0,0) + p(0,1) + p(0,2) + p(0,3) + p(0,4) + p(1,0) + p(1,1) + p(1,2) + p(1,3) + p(1,4) + p(2,0) + p(2,1) + p(2,2) + p(2,3) + p(2,4) + p(3,0) + p(3,1) + p(3,2) + p(3,3) + p(3,4) + p(4,0) + p(4,1) + p(4,2) + p(4,3) + p(4,4).

To find all these values we will construct a table as follows;

P(x,y)           Y=0      Y=1         Y=2      Y=3    Y=4

X=0              0          1/4          1/2        3/4       1      

X=1               1/4        1/2        3/4         1        5/4

X=2             1/2         3/4         1            5/4     3/2

X=3             3/4          1          5/4         3/2      7/4      

X=4               1          5/4         3/2       7/4       2

Now the joint distribution will become,

F(x,y) = 0 + 1/4 + 1/2 + 3/4 + 1 + 1/4 + 1/2 + 3/4 +1  + 5/4 + 1/2 + 3/4 + 1 + 5/4 + 3/2 + 3/4 + 1 + 5/4 + 3/2 + 7/4 + 1 + 5/4 + 3/2 + 7/4 + 2

F(x,y) = 25

Therefore the joint distribution of x and y is 25.

The number of 5 or fewer digits that are even or divisible by 5 and do not contain any repeated digits is 2500.

In a positional numeral system, a numerical digit is a single sign that can be used singly or in combination to represent numbers.

A digit is a part of a set that, when combined, makes up a numeration system.

For example 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 are digits.

The number of even digits 5 is 0,2,4,6,8.

Number of ways we can choose the first digit = 2,4,6,8 (0 cannot be taken in first)

Number of ways we can choose second, third, fourth, and fifth digits = 5

Number of ways or combinations,

4 × 5 × 5 × 5 × 5 = 2500

Step-by-step explanation:

Having at least 1 girl out of 3 children means that there can be 1, 2 or 3 girls out of the 3 children.

So having at lest 1 girl out of 3 children is the same as saying that all 3 children are not boys.

The probability that all 3 children are boys would be

chance that child 1 is a boy * chance that child 2 is a boy * chance that child 3 is a boy = 0.5 * 0.5 * 0.5 = 0.125

And the probability that NOT all 3 children are boys would be

What are the linear equations in two variables?

A linear equation in two variables is one that is written in the form ax + by + c=0, where a, b, and c are real numbers and the coefficients of x and y, i.e. a and b, are not equal to zero. For example, 10x+4y = 3 and -x+5y = 2 are two-variable linear equations.

Let the cost of one hot dog be 'x' dollars and the cost of one water bottle be 'y' dollars.

By using the given data, we can prepare the equations

             4x + 6y = 22 ------(I)

             8x + 3y = 35------(II)

Multiplying equation(I) and taking subtraction, we get

               9y =  9

                 y = 9/9

                 y = 1

Put y = 1 in equation (I), and we get

          4x + 6 = 22

          4x = 22 - 6

          4x = 16

            x = 4

The value b is 8 if m=1 and the line is passing through the point P(-4,4).

The line's equation is expressed in slope-intercept form: y = mx + b, where m represents the slope and b represents the y-intercept. The slope of the line is 3 in our equation, y = 3 x + 5.

Consider the slope-intercept form equation y = 6 x + 9 y=6x+9 y=6x+9. We can find the x and y intercepts. The x-intercept occurs when y = 0, whereas the y-intercept happens when x equals 0. By setting the value of y to zero, we may find the x-intercept.

When an equation is not in the y = mx + b form, we can solve for the intercepts by substituting 0 and solving for the remaining variable.

Let, the slope-intercept form is,

y= mx +b

Given, m=1

The graphic above shows a relation rather than a function because one is mapped to two different values. The relation above would turn into a function, though, if one were instead mapped to a single value. Additionally, output values can be equal to input values.

Phenotypic ratio pertains to the relative number of offspring manifesting a particular trait or combination of traits. It can be determined by doing a test cross and identifying the frequency of a trait or trait combinations that will be expressed based on the genotypes of the offspring.

For example: when a tall plant is crossed to a short plant, some of their offspring will be tall while others will be short. To determine the phenotypic ratio, the number of times the phenotypes (either tall or short) are expressed is counted.
