Answer:

M+N is defined

All others not defined

Step-by-step explanation:

Two matrices can be added or subtracted if and only if they have the same dimensions i.e. they must have the exact same number of rows and number of columns

Only M and N with dimensions (4 x 2) each can be added or subtracted.

(4 x 2 ) means 4 rows and 2 columns

So the only defined operation is
M + N

All the others are not defined

Answer:

[tex]\textsf{De\:\!fined}: \quad \boxed{M + N}[/tex]

[tex]\textsf{Not\:de\:\!fined}: \quad \boxed{N - Q} \quad \boxed{Q + L} \quad \boxed{M - P}[/tex]

Step-by-step explanation:

Generally, a matrix is referred to as [tex]n\times m[/tex] where n is the number of rows and m is the number of columns.

Therefore:

Matrices can be added or subtracted only when they are the same size.

[tex]\boxed{N - Q}[/tex]

Matrices N and Q are different sizes. Therefore, the operation is not defined.

[tex]\boxed{M + N}[/tex]

Matrices M and N are the same size. Therefore, the operation is defined.

[tex]\boxed{Q + L}[/tex]

Matrices Q and L are different sizes. Therefore, the operation is not defined.

[tex]\boxed{M - P}[/tex]

Matrices M and P are different sizes. Therefore, the operation is not defined.

The number of red pencils is found to be 10 such that the ratio of blue pencils to red pencils is 1:2.

Let the number of number of red pencils be 'x'.

Total blue pencils = 5.

Ratio = blue pencils/red pencils

5/x = 1/2

x = 5 x 2

x = 10

Thus, the number of red pencils is found to be 10 such that the ratio of blue pencils to red pencils is 1:2.

The compound interest after 5 years is $7,081.916.

Compound interest:

Compound interest is when you earn interest on both the money you've saved and the interest you earn.

Here we have to find the interest earned after 5 years.

Data given:

There is sufficient data to infer that the valve does not operate as intended at the 0.1 level.

Null hypothesis: H₀ : μ = 7.6

Alternative hypothesis: Hₐ : μ ≠ 7.6

In inferential statistics, the null hypothesis states that two possibilities are equal.

The observed difference is thought to be the sole product of chance, which is the underlying premise.

Statistical tests can be used to calculate the likelihood that the null hypothesis is true.

So,

Null hypothesis: H₀ : μ = 7.6

Alternative hypothesis: Hₐ : μ ≠ 7.6

As the population standard deviation is given when n > 30

So, we'll run the Z test.

Formula: [tex]z=\frac{x-\mu}{\frac{a}{\sqrt{n}}}[/tex]

Replace the values:

[tex]\begin{aligned}& z=\frac{7.7-7.6}{\frac{11.6}{\sqrt{160}}} \\& z=2.449\end{aligned}[/tex]

For the p-value, see the z table.

Consequently, p = 0.9927.

The two-tailed nature of the test So, p = 2(1- 0.9927) = 0.0146

α = 0.1

p value< α

Thus, we disregard the null hypothesis.

Hence, at the 0.1 level, there is enough evidence to conclude that the valve does not function as intended.

Therefore, there is sufficient data to infer that the valve does not operate as intended at the 0.1 level.

Answer:

  13.5, 17.5

Step-by-step explanation:

You have two numbers whose sum is 31 and whose difference is 4. The second number is larger.

Let x represent the larger number. Then the smaller is x-4, and their sum is ...

  x +(x -4) = 31

Simplifying the expression gives ...

  2x -4 = 31

  2x = 35 . . . . . add 4

  x = 17.5 . . . . . divide by 2

  x -4 = 13.5

The two numbers are 13.5 and 17.5.

Using trigonometry identities, we know that the polar form of  -9-9√3i is (D) 18 (cos(4π/3) + isin(4π/3)).

Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions.

There are numerous distinctive trigonometric identities that relate to a triangle's side length and angle.

So, we have -9 - 9√3i:

This quantity has a modulus.

|-9 - 9√3 i| = √((-9)² + (-9√3)²) = √324 = 18

And argument θ to the effect:

tan(θ) = (-9√3) / (-9) = √3

We anticipate that will be between -π and -π/2 radians since -9-9√3i lies in the third quadrant of the complex plane, so that:

θ = arctan(√3) - π = π/3 - π = -2π/3

The polar form is then:

18 (cos(-2π/3) + i sin(-2π/3))

And since -2π/3 is the same angle as 2π - 2π/3 = 4π/3, the right answer is: 18 (cos(4π/3) + i sin(4π/3))

Therefore, using trigonometry identities, we know that the polar form of  -9-9√3i is (D) 18 (cos(4π/3) + isin(4π/3)).

The increase in the salary for Charolette will be $251.65.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

Since Charolette earns 3,595 per month at her job. She will receive a 7% raise. The amount of raise will be calculated by simply multiplying the percentage that she was given for the raise in the salary by the initial salary that she was earning.

This will be illustrated thus:

= Percentage × Salary

= 7% × $3595

What is a standard deviation?

In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.

Answer:

Step-by-step explanation:

You want the domain, range, intercepts, asymptotes, and holes of the rational function f(x) = (2x³ +10x² +8x)/(x³ +7x² +12).

The given function can be simplified by cancelling common factors from numerator and denominator. These cancelled factors show where the holes are in the graph.

  [tex]f(x)=\dfrac{2x^3+10x^2+8x}{x^3+7x^2+12}=\dfrac{2x(x+4)(x+1)}{(x(x+4)(x+3)}=2\left(\dfrac{x+1}{x+3}\right)\quad x\notin\{-4,-3,0\}[/tex]

The function is defined for all real numbers except those where the denominator is zero: {-4, -3, 0}.

The function can produce every output value except the value of the horizontal asymptote: y = 2. The range is all real numbers except 2.

The x-intercept is found where the numerator of the simplified function is zero: x = -1

The y-intercept is the function value at x=0. The function is undefined there, so the y-intercept does not exist. (The limit as x approaches zero is y = 2/3.)

The function has a horizontal asymptote at the y-value corresponding to the ratio of the highest-degree terms of the numerator and denominator: y = 2.

The vertical asymptote is at the uncanceled denominator zero, x = -3.

The holes are where a numerator and denominator factor cancel. The y-value at the hole is the limit of the function value as x approaches the hole location. This is the value of the simplified function.

The holes are (-4, 6) and (0, 2/3).

The box's dimensions that reduce the overall cost of the materials are as follows:

L = W = 16 cm

H = 32 cm

Given,

What is the dimensions of the rectangle?

A rectangle has two dimensions: a length and a width that are both perpendicular to it. The interior of an oval or a triangle also has two dimensions.

Here,

We've got

Volume = 512 cm3 L* W * H

Sides of the box cost = 1 cent/cm²

Top and bottom cost 2 cent/cm²

Then,

Box dimensions that reduce the overall cost of materials used

We are aware of

L× W × H = 512 cm³

Where,

L stands for length, W for width, and H for height.

So, when we reduce the cost function

C(L, W, H) = (1) 1 H + (2) 1 (L + W)

Thus insert H.

Replacing H with 512/LW yields,

C(L, W) = 512(1/L, 1/W), plus 2LW

So

When both partial derivatives are 0, there will be a minimum cost.

512/L2 - 2W = dC/dL = 0

So

512/W2 - 2L = 0 for dC/dW.

L = 256/W²

Now

The answer to the aforementioned equation is

L = W = (256)⁻³ = 16cm

And

H = 512/16 = 32

H = 32 cm

Consequently, the box's measurements that reduce the overall cost of the materials utilized are:

L = W = 16 cm

H = 32 cm
