Answer:

(x-6)(x+6) pairs with x^2-36

9x^2-1 pairs with (3x-1)(3x+1)

4(x+2)(x-2) pairs with 4x^2-16

Step-by-step explanation:

If you're using PLATO this is the correct answer I just did the problem myself

I'll even explain below and drop the image screenshot

The equation x2 − 36 can be factored into (x − 6)(x + 6) using the difference of two squares.

The equation 9x2 − 1 is the difference of two squares, (3x)2 – 12, so it factors into (3x − 1)(3x + 1).

We can factor 4 out of the expression 4x2 − 16 to get 4(x + 2)(x − 2).

The pairs are:

A binomial is an algebraic expression with two terms. as an example, a + b, x - y, etc are binomials. We have a hard and fast of algebraic identities to locate the expansion when a binomial is raised to exponents 2 and three.

There are 3 major types of algebraic expressions which encompass: Monomial Expression, Binomial Expression, and Polynomial Expression.

The correct answer is 60%

Explanation:

A percentage represents a proportion of a total or 100% by using a number from 1 to 100. In this context, the first step is to count how many squares there are and how many were painted. This leads to the following results:

40 squares in total

24 painted squares

Knowing these two details it is possible to calculate the percentage. Follow this process:

- Write the values

40 squares = 100 % or total

24 squares = x (the value that needs to be found)

- Cross multiply to create an equation and solve this equation

40 x = 2400

x = 2400 ÷ 40

x = 60

The percentage that was painted was 60%

Answer:

80

Step-by-step explanation:

You can figure this out by creating an equation:

1/10 x=8        (This shows that 8 is 1/10 of number x)

x=80            (Solve the equation by multiplying by ten)  

Answer:One tenth is the same as one out of ten parts. It is a common fraction that means the same as 10% or 0.1.

Step-by-step explanation:

Hey there! I'm happy to help!

First let's combine all of the terms with a.

2a+2a=4a

Now the ones with b.

3b-b=2b

And the ones with c.

-4c+2c=-2c

So, our simplified expression is 4a+2b-2c.

Step-by-step explanation:

it's in two way factorial design there can be a maximum of two interactions in one main effect

There are 2 sources of variation in a two - way ANOVA with interaction.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

A two-way ANOVA with interaction.

Now,

Here, A two-way ANOVA with interaction.

We know that;

Two-way ANOVA include two factors, each with two or more levels (groups), and collectively, factors are often referred to as the main effects in these types of ANOVA. The other source of variation in a two-way ANOVA is the interaction between the two factors.

Thus, Number of sources of variation = 2

Answer and Step-by-step explanation:

A) For the model to be a probability distribution, it has to follow two conditions:

1) The probability of each value of the discrete random variable is between, and included, 0 and 1:

2) The sum of all probabilities is 1;

In the table shown, the probabilities are from 0 to 0.3 - between 0 and 1;

Adding the probabilities: 0 + 0.3 + 0.1 + 0.3 + 0.3 = 1

Therefore, this model is a valid probability distribution model.

B) They are discrete because each value correspond to a finite number of possible values.

C) Expected value is calculated by

[tex]E(X) = \Sigma xP(x)[/tex]

[tex]E(X) = 0.0 + 1*0.3 + 2*0.1 + 3*0.3 + 4*0.3[/tex]

E(X) = 2.6

D) P(X=3) = P(3), which means probability of 3:

P(X=3) = 0.3

E) P(X<4): probabilities of values of X that are less than 4:

P(X<4) = P(0) + P(1) + P(2) + P(3)

P(X<4) = 0 + 0.3 + 0.1 + 0.3

P(X<4) = 0.7

F) P(X>0) = P(1) + P(2) + P(3) + P(4)

P(X>0) = 0.3 + 0.1 + 0.3 + 0.3

P(X>0) = 1

G) P(X=5) = P(5)

There is no probability of P(5) because the model doesn't "cover" that number.

H) P(X=0) = P(0)

P(X=0) = 0

I) The total area of any density curve is 1 because it represents all the possible values a variable can assume.

The answers are given as- A) Model is a valid probability distribution model.

B ) The described random variable is discrete.

C ) Mean E(X) = 2.6

D)  P(X=3) = 0.3

E )  P(X < 4) = 2.6

F )  P(X > 0) = 1

G ) There is no probability of P(5)

H ) P(X = 0) = 0

I ) The total area of any density curve is 1

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

A) For the model to be a probability distribution, it has to follow two conditions:

In the table shown, the probabilities are from 0 to 0.3 - between 0 and 1;

Adding the probabilities: 0 + 0.3 + 0.1 + 0.3 + 0.3 = 1

Therefore, this model is a valid probability distribution model.

B) They are discrete because each value correspond to a finite number of possible values.

C) Expected value is calculated by

E(x) = ∑ P(x)

E ( x) = 0 + ( 1 x 0.3 ) + ( 2 x 0.1 ) + 3 ( 0.3 ) + 4 ( 0.3 )

E(X) = 2.6

D) P(X=3) = P(3), which means a probability of 3:

P(X=3) = 0.3

E) P(X<4): probabilities of values of X that are less than 4:

P(X<4) = P(0) + P(1) + P(2) + P(3)

P(X<4) = 0 + 0.3 + 0.1 + 0.3

P(X<4) = 0.7

F) P(X>0) = P(1) + P(2) + P(3) + P(4)

P(X>0) = 0.3 + 0.1 + 0.3 + 0.3

P(X>0) = 1

G) P(X=5) = P(5)

There is no probability of P(5) because the model doesn't "cover" that number.

H) P(X=0) = P(0)

P(X=0) = 0

I) The total area of any density curve is 1 because it represents all the possible values a variable can assume.

Answer:

[tex]x=\frac{23}{6}[/tex] or [tex]4.6[/tex]

Step-by-step explanation:

Answer:

4k - 16 thats the answer

Hey there! I'm happy to help!

We are multiplying k-4 by 4. This means that we multiply each term in k-4 by 4.

4(k)=4k

4(-4)=-16

So, our simplified expression is 4k-16.

Have a wonderful day! :D

Answer:

7/16

Step-by-step explanation:

If it's easier to visualize, we can convert every into 1/16 including the graph to compare.

To convert the graph (currently in 1/8), we divide each segment to produce 16 segments, 6 of which are shaded (6/16 = 3/8).

The other fractions converted to 1/16 are as follows:

1/4 --> 4/16

7/16 --> 7/16

1/8 --> 1/16

3/16 --> 3/16

Now it's easy to tell which fraction is greater than the area represented in the model!

Answer:

First is equivalent then 29 last equivalent

Step-by-step explanation:

If both expressions have the same value,  then they are equal to each other.

The equivalent is the expressions that are in different forms but are equal to the same value.

Consider the expressions 5 + 8k and 8k + 5.

Using k = 3

 5 + 8k = 8k + 5

5 + 8(3) = 8(3) + 5

5 + 24 = 24 + 5

     29 = 29

Using k = 5

 5 + 8k = 8k + 5

5 + 8(5) = 8(5) + 5

 5 + 40 = 40 + 5

        45 = 45

If both expressions have the same value after substituting and simplifying two different values for the variable, then they are equal to each other.

You can multiply ANYTHING. Just make sure that when you multiply, you change the exponents properly. Combining like terms is basically like normal addition. For example, you cannot add 6x +3y because they have different variables. If it was 3x+6x, then you can add it because they are like terms.

Answer:

(x-2)^2

Step-by-step explanation:

The blue graph is shifted two units to the right of the "original" function x^2 (red). Let's recall the vertex form of a quadratic:

a (x-h)^2 + k

where a represents a constant that describes the opening of the parabola (up/down); h represents horizontal shift; and k represents vertical shift.

The blue graph is two units to the right (+2), there is NO vertical shift and NO change in how the parabola opens.

So, let's plug the appropriate values into vertex form:

(x-(+2))^2

= (x-2)^2
