Quick Copy: 5 + 0.06x

Copy Place: 10 + 0.04x

5 + 0.06x = 10 + 0.04x

0.02x = 5

x = 5/0.02

x = 250

Answer: 250 pages

Check

Quick Copy: 5 + 0.06(250) = 5 + 15 = 20

Copy Place: 10 + 0.04(250) = 10 + 10 = 20

For 250 copies, both places cost $20. 250 copies is the correct answer.

Answer: C

Step-by-step explanation:

Use the graph ln the left side.

The description of the graph of the function \(y = \frac{1}{x + 2} + 1\) is the description (c)

The equation is given as:

y = StartFraction 1 Over x + 2 EndFraction + 1?

Rewrite properly as:

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

The above equation is the translated equation from an inverse function

The graph of the function pass through the points (0,1.5) and (-3,0)

Hence, the graph of f(x) = √x is (c) On a coordinate plane, 2 curves are shown. Both curves have an asymptote at x = -2. One curve opens up and to the right in quadrants 1 and 2. It crosses the y-axis at (0, 1.5). The other curve opens down and to the left, and it crosses the x-axis at (-3, 0).

Answer:

H0 : μ = 4.50

H1 : μ > 4.50

Test statistic = 1.525

we conclude that there is no sufficient evidence to conclude that the mean wait time for customers is longer than 4.50.

Step-by-step explanation:

H0 : μ = 4.50

H1 : μ > 4.50

Test statistic :

(xbar - μ) ÷ s/sqrt(n)

(4.94 - 4.50) ÷ 2.10/ sqrt(53)

0.44 / 2.10/ sqrt(53)

= 1.525

α = 1 - 98% = 0.02

Decision region :

Reject H0 ; if Pvalue < α

Pvalue = p(Z < 1.525) = 0.936

Pvalue = 0.936

Since Pvalue > α ; We fail to reject H0

Hence, we conclude that there is no sufficient evidence to conclude that the mean wait time for customers is longer than 4.50.

Rates of change are the change of a quantity over another.

The rate of change in height of the water level is 36.51 cm per second.

Let the length of the top square be s, and the height be h.

The volume of the pyramid is:

\(\mathbf{V = \frac{1}{3}s^2h}\)

At time t, we have:

\(\mathbf{V = \frac{1}{3}s(t)^2h(t)}\)

The relationship between the side length and height is:

\(\mathbf{s : h=6 : 13}\)

Express as fractions

\(\mathbf{\frac{s }{ h}=\frac{6 }{ 13}}\)

Make s the subject

\(\mathbf{s=\frac{6 }{ 13}h}\)

So, we have:

\(\mathbf{V = \frac{1}{3}s^2(t)h(t)}\)

\(\mathbf{V = \frac{1}{3} \times (\frac{6 }{ 13}h(t))^2 \times h(t)}\)

\(\mathbf{V = \frac{1}{3} \times \frac{36}{ 169}h^2(t) \times h(t)}\)

\(\mathbf{V = \frac{1}{3} \times \frac{36}{ 169}h^3(t)}\)

Differentiate

\(\mathbf{V'(t) =3 \times \frac{1}{3} \times \frac{36}{ 169}h^2(t) \times h'(t)}\)

\(\mathbf{V'(t) =\frac{36}{ 169}h^2(t) \times h'(t)}\)

Make h'(t) the subject

\(\mathbf{h'(t) = \frac{169 \times V'(t)}{36 \times h^2(t)}}\)

The water level rises constantly at 70 cm^3/s, and the water level is 3 cm.

So, we have:

\(\mathbf{V'(t) = 70}\)

\(\mathbf{h(t) = 3}\)

\(\mathbf{h'(t) = \frac{169 \times V'(t)}{36 \times h^2(t)}}\) becomes

\(\mathbf{h'(t) = \frac{169 \times 70}{36 \times 3^2}}\)

\(\mathbf{h'(t) = \frac{169 \times 70}{36 \times 9}}\)

\(\mathbf{h'(t) = 36.51}\)

Hence, the rate of change in height of the water level is 36.51 cm per second.

Looking at the distribution sets 1-8 the one that seems to be closest to the mean is distribution 1 because all the data of distribution 1 lie on 5.

The distribution closest to the mean is determined by comparing the mean of the dataset, to the given mean.

The mean of the various distributions is determined as;

Distibution 1; mean = (9 x 5) = 45/9 = 5

Distibution 2; mean = (2x3  + 3 +  4x2  +  8 + 9 + 11) /9 = 5

Distibution 3; mean = (2x3  +  4x2  +  5 + 7 + 9 + 10) /9 = 5

Distibution 4; mean = (2x3  +  4x2  +  5 + 7 + 9 + 10) /9 = 5

The mean of the remaining distributions, from 5 to 8 is also 5, as already given in the statement.

If we look at all the distributions, we would see that, all the data of distribution 1 lie on 5, making it the most closest the mean of the distribution.

Thus, looking at the distribution sets 1-8 the one that seems to be closest to the mean is distribution 1 because all the data of distribution 1 lie on 5.

The average number of students who are afraid of spiders and snakes is 15. (Option C).

To calculate the average number of students who are afraid of spiders and snakes, you need to add the number of students afraid of spiders and the number of students afraid of snakes, and then divide by 2 (since there are two categories being considered: spiders and snakes).

Average = (Number of students afraid of spiders + Number of students afraid of snakes) / 2

Given the information:

Number of students afraid of spiders = 18

Number of students afraid of snakes = a little more than 11 (let's consider 12 for calculation)

Average = (18 + 12) / 2 = 30 / 2 = 15

Answer:  Choice A

y = (-2/3)x + 12

================================================

Work Shown:

We will only focus on the two points that are on the regression line.

Those two points are (3,10) and (12,4)

Let (x1,y1) = (3,10) and (x2,y2) = (12,4)

Find the slope of the line through (x1,y1) = (3,10) and (x2,y2) = (12,4)

m = (y2 - y1)/(x2 - x1)

m = (4 - 10)/(12 - 3)

m = -6/9

m = -2/3

Plug m = -2/3 and (x1,y1) = (3,10) into the point slope formula

Solve for y.

y - y1 = m(x - x1)

y - 10 = (-2/3)(x - 3)

y - 10 = (-2/3)x + (-2/3)(-3) ... distribute

y - 10 = (-2/3)x + 2

y - 10 + 10 = (-2/3)x + 2 + 10 .... add 10 to both sides

y = (-2/3)x + 12

This matches up with what the graph shows because the regression line intersects 12 on the y axis, so the y intercept is 12.

y = (-2/3)x + 12 is in the form y = mx+b with m = -2/3 as the slope and b = 12 as the y intercept.

w/–3 + 14 = 5

⇛ w/–3 = 5 – 14

⇛ w/–3 = – 11

⇛ w = –11 × (–3)

⇛ w = 33

Out of the 400 surveyed students, 327 were either seniors or commuters.

To find the number of students who were either seniors or commuters out of the 400 surveyed students, we need to add the number of seniors and the number of commuters while avoiding double-counting those who fall into both categories.

According to the information given:

There were 262 seniors.

There were 215 commuters.

150 of the seniors were also commuters.

To avoid double-counting, we need to subtract the number of seniors who were also commuters from the total count of seniors and commuters.

Seniors or commuters = Total seniors + Total commuters - Seniors who are also commuters

= 262 + 215 - 150

= 327

Therefore, out of the 400 surveyed students, 327 were either seniors or commuters.

It's important to note that in this calculation, we accounted for the overlap between seniors and commuters (150 students who were both seniors and commuters) to avoid counting them twice.

This ensures an accurate count of the students who fall into either category.
