Answer:

-∞ < y < ∞

Step-by-step explanation:

Range corresponds to the values on the y-axis and Domain corresponds to values on the x-axis. Here if see the graph the range depends on values on y-axis and we can see that the the graph goes to -∞(-negative infinity) to +∞(positive infinity)  so the answer is

-∞ < y < ∞

Answer:

The range is  -∞< y < ∞, below is the explanation of how to get range.

Step-by-step explanation:

Given:

      Graph of a function h(x).

To find:

      The range of the function in inequality notation.

The range is all possible y-values of the function. Let's find all possible y values from the graph.

If we see the graph, it has a vertical asymptote at x=1 and a slant asymptote.

But it tool all y values from -infinity to infinity.

So, we can write range as -∞< y < ∞ because both sides of the function go and so on below the x-axis and go and so on above the x-axis.

The range is  -∞< y < ∞ .

Answer:

The mean and standard devaition of W are 6 and 31 respectively.

Step-by-step explanation:

Given that:

W = 7 + 2X

Variance (W) = Variance(7 + 2X)

For a term constant term, the variance is zero.

So;

[tex]W = Var (2X)[/tex]

W = 4 × Var(X)

W = 4 × (SD (X))²

W = 4 × (3)²

W = 4 × 9

W = 36

Thus, Variance (W) = 36

The standard deviation of W = [tex]\sqrt{variance}[/tex]

W = [tex]\sqrt{36}[/tex]

W = 6

Also;

E(W) = E(7 +2 X)

E(W) = 7 + 2 × E(X)

where;

mean X = 12

E(W) = 7 + 2(12)

E(W) = 31

Thus, the mean and standard devaition of W are 6 and 31 respectively.

The mean and the standard deviation of W are 31 and 6 respectively.

The given parameters are:

[tex]\mathbf{\bar x_x = 12}[/tex]

[tex]\mathbf{\sigma_x = 3}[/tex]

The definition of W is given as:

[tex]\mathbf{W = 7 + 2X}[/tex]

This means that:

[tex]\mathbf{Var(W) = Var(7) + Var(2X)}[/tex]

So, we have:

[tex]\mathbf{Var(W) = 0 + Var(2X)}[/tex] --- the variance of a constant term is 0

[tex]\mathbf{Var(W) = Var(2X)}[/tex]

This gives

[tex]\mathbf{Var(W) = 2^2 \times Var(X)}[/tex]

We have:

[tex]\mathbf{Var(X) = \sigma^2_x}[/tex]

So, the equation becomes

[tex]\mathbf{Var(W) = 2^2 \times \sigma^2_x}[/tex]

[tex]\mathbf{Var(W) = 2^2 \times 3^2}[/tex]

[tex]\mathbf{Var(W) = 36}[/tex]

The standard deviation is then calculated as:

[tex]\mathbf{\sigma_W = \sqrt{Var(W)}}[/tex]

[tex]\mathbf{\sigma_W = \sqrt{36}}[/tex]

[tex]\mathbf{\sigma_W = 6}[/tex]

The mean is then calculated as:

[tex]\mathbf{E(W) = E(7 + 2X)}[/tex]

This gives

[tex]\mathbf{E(W) = 7 + 2E(X)}[/tex]

So, we have:

[tex]\mathbf{E(W) = 7 + 2 \times 12}[/tex]

[tex]\mathbf{E(W) = 31}[/tex]

Hence, the mean and the standard deviation of W are 31 and 6 respectively.

Answer:

8posters are created

Step-by-step explanation:

Given the function that represents the total number of posters expressed as

f(t)= 5t+3

The total posters every hour occur at t = 1hr

Substitute into the equation

f(1) = 5(1)+3

f(1) = 5+3

f(1) = 8

Hence the function f represents the fact that every hour, 8posters are being created

Determine how far he walked in one loop

This question is incomplete, as the playground diagram and dimensions are missing. However, I'll answer on a general terms.

What this question requires is to calculate the perimeter of the playground.

Assume that the playground is rectangular and the dimensions are: 2  meters by 3 meters.

The distance walked will be calculated using the following perimeter formula.

[tex]Distance = 2(2m + 3m)[/tex]

[tex]Distance = 2(5m)[/tex]

[tex]Distance = 10m[/tex]

If it is a square with 5m as the length of one of its side, the distance would be:

[tex]Distance = 4 * 5m[/tex]

[tex]Distance = 20m[/tex]

So basically, all you need to do is calculate the perimeter of the playground.

Answer:

62

Step-by-step explanation:

Turn the percentage into a decimal.

50% = 0.5

Divide.

31 / 0.5 = 62

Best of Luck!

Answer:

62

Step-by-step explanation:

50% is technically 1/2 right?

So, if 31 is half of this mysterious number then we just need to times 31 by 2.

Therefore, 31 * 2 = 62.

We can check this by multiplying 62 by .50 (remember that when using percents in an operation we move the decimal over twice)

62 * .50 = 31

Answer:

The measure of the complement =

= 80°

The measure of the supplement=

= 170°

Step-by-step explanation:

Let

90-x equal the degree measure of its complement

180-x equal the degree measure of its supplement.

We are told in the question that: the supplement of a given angle is 10 degrees more than twice its complement.

Hence, the Equation is;

(180 - x) = 10° + 2(90 - x)

180 - x = 10 + 180 - 2x

Collect like terms

-x + 2x = 10 + 180 - 180

x = 10°

Hence,

The measure of the complement =

90 - x

= 90 - 10

= 80°

The measure of the supplement=

180 - x

= 180 - 10

= 170°

Answer:

378

Step-by-step explanation:

Remark

This is a question that all investors in stocks should be aware off. It does not come back to 450 dollars.

Step One

Find out the price of the discounted camera.

40% reduction price =  450 - (40/100)*450

40% reduction price = 450 - 180 = 270

Step Two

Now add 40% onto the new price.

New price = Reduced price + 40% of reduced price

New Price = 270 + 40%* 270

New Price = 270 + 108

New Price = 378

Remark

The reason stock investors should be aware of this is that if you take a 40% loss on a stock it takes more than a 40% gain to make the price of your stock loss back.

Answer:

She added incorrectly

Step-by-step explanation:

Answer should be (22, -26) but Kelcy got wrong because she has taken -1 in third step instead of taking 1 because -4 +5 is 1.

A vector is a quantity or phenomenon that has two independent properties: magnitude and direction.

Let  u = ⟨9, –2⟩, v = ⟨–4, 3⟩, and w = ⟨5, 1⟩

3u – 5(v + w)

3(9, -2)-5(⟨–4, 3⟩+⟨5, 1⟩)

Multiply 3 to (9, -2) and add v and w

(27,-6)-5(1,4)

(27, -6)-(5, 20)

Subtract the vectors

(27-5, -6-20)

(22, -26)

The answer should be (22, -26) but Kelcy got wrong because she has taken -1 in third step instead f taking 1 because -4 +5 is 1.

Hence,  answer should be (22, -26) but Kelcy got wrong because she has taken -1 in third step instead f taking 1 because -4 +5 is 1.

Answer: y => 12

y is greater than or equal to 12

Step-by-step explanation:

So they give you the function of y = 2x + 4 and the domain of all real numbers is greater than or equal to 4.

In simple term, the domain is x => 4, x is greater than or equal to 4.

Using that we can substitute the x in the function by 4.

y = 2(4) + 4

y = 8 + 4

Which gave us the answer of 12.

Since the domain can be anything greater than 4 or 4. We can expect the

same for the range.

Then the range will be 12 or greater than 12. For example, 13, 14, 15, 16...

Ex. y = 2(5) + 4

y = 10 + 4

y = 14

Ex. y = 2(4.5) + 4

y = 9 + 4

y = 13

Answer:

The fraction of its drop height after the fourth bounce is

[tex]\displaystyle \frac{16}{625}[/tex]

Step-by-step explanation:

Let's suppose the rubber ball is dropped from a height H0. Every time the ball bounces back it reaches 8/10 of the initial drop height.

The ball's height H(x) after bounce number x is:

[tex]\displaystyle H(x)=H_o\left(\frac{8}{20}\right)^x[/tex]

Simplifying:

[tex]\displaystyle H(x)=H_o\left(\frac{2}{5}\right)^x[/tex]

After the fourth bounce, the height is:

[tex]\displaystyle H(4)=H_o\left(\frac{2}{5}\right)^4[/tex]

[tex]\displaystyle H(4)=H_o\frac{2^4}{5^4}[/tex]

[tex]\displaystyle H(4)=H_o\frac{16}{625}[/tex]

The fraction of its drop height after the fourth bounce is

[tex]\mathbf{\displaystyle \frac{16}{625}}[/tex]
