Answer:

C

Step-by-step explanation:

consider the right side

(x + 2)²

= (x + 2)(x + 2) ← expand using FOIL

= x² + 2x + 2x + 4 ← collect like terms

= x² + 4x + 4 = left side

then x² + 4x + 4 is a valid perfect square binomial

x² + 4x + 4 = (x + 2)²

then

x² + 4x + 4

Statement 2

consider the right side

(a + b)²

= (a + b)(a + b) ← expand using FOIL

= a² + ab + ab + b² ≠ left side

then

a² + 2ab + ab is not a valid perfect square binomial

The given equation is x2y3 + x(1+y 2)y' = 0. This is not an exact equation, as the derivative of F(x,y) is not equal to zero. To make this equation exact, we need to multiply it by an integrating factor.

The integrating factor (I.F.) of a differential equation is a function of the independent variable, which can be used to transform an equation into an exact equation. An exact equation is one in which the derivative of F(x,y) is equal to zero. To find the integrating factor, we need to multiply the given equation by I.F. and set the derivative of F(x,y) to zero.

To find the I.F., we need to divide both sides of the equation by x(1+y2):
x2y3 + x(1+y 2)y' / x(1+y2) = 0 / x(1+y2)

Rearranging this equation, we get:
y' + (x2y3 / x(1+y2)) = 0

Now, we can integrate both sides of the equation,
∫y' + (x2y3 / x(1+y2)) dx = 0

This gives us an expression for the I.F.,
I.F. = exp(∫(x2y3 / x(1+y2))dx)

Now, to make the equation exact, we need to multiply the given equation with the integrating factor. This gives us:    I.F. x x2y3 + I.F. x x(1+y2)y' = 0

Simplifying this equation, we get:
F(x,y) = G(x) + H(y) = K

Where K is a constant. Thus, we have now converted the given equation into an exact equation.

The factors of the quadratic equation are (x+3) and (x-15).

The factors of \(x^2-12x-45\\\).

\(x^2-12x-45\\\)

As we can see in the quadratic equation the value of ac is -45x². therefore, we need to divide -12x into two parts such that their sum must give -12x and their product gives us -45x².

therefore, dividing -12x into -15x and 3x,

\(x^2-15x+3x-45\\\)

Taking common out,

\(x^2-15x+3x-45\\x(x-15)+3(x-15)\\(x+3)(x-15)\)

The value of the sum of squares due to regression is 18.43.

Given the total sum of squares (SST) is 25.32 and the sum of squares due to error (SSE) is 6.89.

A common measure used in regression analysis is the sum of squares total (SST). The square of each difference is added to the sum of squares to obtain the squared disparities between individual data points and their mean. The variance is calculated using the sum of squares, which is also used to assess how well a regression curve fits the data.

We will use the total sum of squares (SST) is given as the summation of the sum of squares due to regression (SSR) and sum of squares error (SSE);

SST = SSR + SSE

Here, SST=25.32 and SSE=6.89

Substitute the values in the formula, we get

25.32=SSR+6.89

Now, we will subtract 6.89 from both sides, we get

25.32-6.89=SSR+6.89-6.89

18.43=SSR

Hence, the value of the sum of squares due to regression (SSR) when the total sum of squares (SST) is 25.32 and the sum of squares due to error (SSE) is 6.89 is 18.43.

We have found a vector in W and a scalar outside of W such that their product is not in W, which means that W is not closed under scalar multiplication. Hence, W cannot be a subspace of R2.

To show that a subset is a subspace of a vector space, we need to verify three conditions:

Closure under addition: For any vectors u and v in the subset, their sum u + v is also in the subset.

Closure under scalar multiplication: For any vector u in the subset and any scalar c, the product cu is also in the subset.

Contains the zero vector: The subset contains the zero vector.

In this case, W is defined as the set of all vectors in R2 whose second component is the cube of the first. We can write this as:

W = {(x, y) ∈ R2 | y = x^3}

Now, to show that W is not closed under scalar multiplication, we need to find a vector in W and a scalar outside of W such that their product is not in W.

Let's consider the vector (1, 1), which belongs to W since 1 = 1^3. If we multiply this vector by the scalar 2, we get:

(2, 2) = 2(1, 1)

However, (2, 2) does not belong to W because 2 is not equal to 1^3. Therefore, we have found a vector in W and a scalar outside of W such that their product is not in W, which means that W is not closed under scalar multiplication. Hence, W cannot be a subspace of R2.

Hey, there!!

You can solve it simply,

1.

Given,

x= 1 , y=2 , z= 3

To solve:

\( = \frac{1}{ {x}^{2} } - \frac{x}{y + z} \)

\( = \frac{1}{ {1}^{2} } - \frac{1}{2 + 3} \)

\( = 1 - \frac{1}{5} \)

Taking LCM,

\( = \frac{5 - 1}{5} \)

Therefore, the final answer is 4/5.

2.

Given,

x= 1 , y= -2, z= -1.

To solve:

\( = \frac{1}{ {x}^{2} } - \frac{x}{y + z} \)

\( = \frac{1}{ {1}^{2} } - \frac{1}{ - 2 - 1} \)

Taking LCM,

\( = \frac{ - 3 - 1}{ - 3} \)

\( = \frac{ - 4}{ - 3} \)

Cancelling the minus sign,

\( \frac{4}{ 3} \)

is the final answer.

3.

Given,

x= -3, y= -1, z= 4

To solve:

\( = \frac{1}{ {x}^{2} } - \frac{x}{y + z} \)

\( = \frac{1}{ {( - 3)}^{2} } - \frac{ - 3}{ - 1 + 4} \)

\( = \frac{1}{9} - ( - 1)\)

\( = \frac{1 + 9}{9} \)

Therefore, the answer is 10/9.

4.

Given,

x= 1/2, y=1, z=1.

To solve:

\( = \frac{1}{ {x}^{2} } - \frac{x}{y + z} \)

\( = \frac{1}{ ( { \frac{1}{2}) }^{2} } - \frac{ \frac{1}{2} }{1 + 1} \)

Simplifying them ,

\(1 \times \frac{4}{1} - \frac{1}{2} \times 2\)

No inferences can be made without performing a hypothesis test

A hypothesis test is a statistical test used to determine whether a specific hypothesis about a population parameter is supported by the data. In this test, a null hypothesis (H0) is stated, which is usually the assumption that the population parameter is equal to a specific value or falls within a certain range. An alternative hypothesis (Ha) is also stated, which is usually the opposite of the null hypothesis.

The next step is to collect data and use statistical techniques to calculate a test statistic, which measures how far the sample data deviates from the null hypothesis. The test statistic is compared to a critical value in a probability distribution, such as a t-distribution or z-distribution, which is determined based on the level of significance (alpha) and the degrees of freedom

The odds in favor of obtaining a number divisible by 3 or 4 in a single roll of a die are 7:5 or 7/5.

The probability of obtaining a number divisible by 3 or 4 in a single roll of a die can be found by adding the probabilities of rolling 3, 4, 6, 8, 9, or 12, which are the numbers divisible by 3 or 4.

There are six equally likely outcomes when rolling a die, so the probability of obtaining a number divisible by 3 or 4 is:

P(divisible by 3 or 4) = P(3) + P(4) + P(6) + P(8) + P(9) + P(12)

P(divisible by 3 or 4) = 2/6 + 1/6 + 1/6 + 1/6 + 1/6 + 1/6

P(divisible by 3 or 4) = 7/12

The odds in favor of an event is the ratio of the probability of the event occurring to the probability of the event not occurring. Therefore, the odds in favor of obtaining a number divisible by 3 or 4 in a single roll of a die are:

Odds in favor = P(divisible by 3 or 4) / P(not divisible by 3 or 4)

Odds in favor = P(divisible by 3 or 4) / (1 - P(divisible by 3 or 4))

Odds in favor = 7/5

Answer:

the line through the points negative 6 comma 0 and 0 comma negative 2

Step-by-step explanation:

Rewrite the equation to something you are familiar with such as the slope intercept form; y = mx + b. This means you need to solve for y.

3x + 9y = -18 --- divide everything by 3.

x + 3y = -6

3y = -6 - x

y = -2 - 1/3x

your slope is -1/3 and your y intercept is - 2.

remember, y-intercept is when x = 0. therefore, when x = 0, y = -2.

write as an ordered pair (0, -2). the only option that has (0, -2) is the second one.

Therefore, the line through the points negative 6 comma 0 and 0 comma negative 2.

AThe area of an equilateral triangle is given by the formula:

A = (sqrt(3)/4) * s^2

where A is the area and s is the length of one side.

If the original length of the side is x, then the new length is 6x. Therefore, we can write:

A(6x) = (sqrt(3)/4) * (6x)^2

Simplifying:

A(6x) = (sqrt(3)/4) * 36 * x^2

A(6x) = 9 * sqrt(3) * x^2

Therefore, the function representing the area of an equilateral triangle with sides of length six times the original length is:

A(6x) = 9 * sqrt(3) * x^2:

Given :

A kitchen supply outfit makes spoons and forks for sale. It costs the store $2 to buy the supplies needed to make a fork and $1 for the supplies to make a spoon. The store sells the forks for $4 and the spoons for $5.

Last month they spent $39 on supplies and sold all the forks and spoons they made using those supplies for $93.

To Find :

How many forks and spoons did the company make.

Solution :

Let, number of forks and spoons the company made are f and s.

For buying from the kitchen the equation is :

2f + s = 39    ....1)

For selling the equation will be :

4f + 5s = 93  ....2)

Multiplying equation 1) by 5 and subtracting equation 2) from it we get :

(10f + 5s) - ( 4f + 5s) = 195 - 93

6f = 102

f = 17  and s = 5

Therefore, the company make 17 forks and 5 spoons.

The equivalent expression to the given one is -sin(pi/6).

The given expression is:

sin(7pi/6)

Where the argument is in radians.

Remember that:

sin(a + b) = sin(a)*cos(b) + sin(b)*cos(a)

Now we can rewrite:

sin(7pi/6) = sin(pi + pi/6)

Then we can use the above relation to rewrite:

sin(pi + pi/6) = sin(pi)*cos( pi/6) + sin(pi/6)*cos(pi)

And we know that:

sin(pi) = 0

cos(pi) = -1
