In a survey, 10 people were asked how much they spent on their child's last birthday gift. The results were roughly bell-shaped with a mean of $49 and standard deviation of $2. Find the margin of error at a 80% confidence level.

Give your answer to two decimal places

Answers

Answer 1

Given the data that we have here where the number of people in the survey is 10, s = 2 and mean = 49, the margin of error is given as 0.76

How to solve for the margin of error

The margin of error can be used to provide the data that has to do with the amount of sampling error that would be in a given data statistic.

We would have to calculate the amount of error using the data that we have below.

We have the following values

number n = 10

mean u = 49

standard deviation sd = 2

The level of confidence c i = 80% = 0.80

we have to find the critical value

degree of freedom = 1 - 0.80

= 0.20

zα/2

= 0.20 / 2 = 0.10

= 1.383

The margin of error

= zα / 2 * s / √n

= 1.383 * 2/√10

= 1.383 x 2 / 3.623

= 1.383 x 0.552028

= 0.7634

The calculated margin of error is given as  0.7634

the angle t is an acute angle and sin t and cost t are given. Use identities to find tan t , csc t, sec t, and cot t. where necessary, rationalize demonstrations.sin t= 7/25, cos t= 24/25

Answers

Answer:

tan t = 7/24

csc t = 25/7

sec t = 25/24

cot t = 24/7

Explanation:

From the question, we're told that sin t = 7/25 and cos t = 24/25. Since we know the identities of sine and cosine to be as follows we can go ahead and determine tan t as shown below;

[tex]\begin{gathered} \sin t=\frac{opposite}{\text{hypotenuse}}=\frac{7}{25} \\ \cos t=\frac{adjacent}{\text{hypotenuse}}=\frac{24}{25} \\ \therefore\tan t=\frac{opposite}{\text{adjacent}}=\frac{7}{24} \end{gathered}[/tex]

Let's go ahead and find cosecant t (csc t);

[tex]\csc t=\frac{1}{\sin t}=\frac{1}{\frac{7}{25}}=1\times\frac{25}{7}=\frac{25}{7}[/tex]

For sec t, we'll have;

[tex]\sec t=\frac{1}{\cos t}=\frac{1}{\frac{24}{25}}=1\times\frac{25}{24}=\frac{25}{24}[/tex]

For cot t;

Solve the equation 20 +7k = 8(k + 2).

Answers

Answer:

Step-by-step explanation:

1. Write the expression.

[tex]20 +7k = 8(k + 2)[/tex]

2. Solve the parenthesis on the right hand side of the equation.

[tex]20 +7k = 8k+16[/tex]

3. Subtract 20 from both sides of the equation.

[tex]-20+20 +7k = 8k+16-20\\ \\7k = 8k-4[/tex]

4. Subtract 8k from both sides of the equation.

[tex]7k-8k = 8k-4-8k\\ \\-k = -4[/tex]

5. Multiply both sides by "-1".

[tex](-1)-k = -4(-1)\\ \\k=4[/tex]

6. Verify.

[tex]20 +7(4) = 8((4) + 2)\\ \\20 +28 = 8(6)\\ \\48=48[/tex]

7. Express the result.

[tex]k=4[/tex].

Answer:

k = 4

Step-by-step explanation:

a) Simplify both sides of the equation.

20 + 7k = 8(k + 2)

20 + 7k = (8)(k) + (8)(2)

20 + 7k = 8k + 16

7k + 20 = 8k + 16

b) Subtract 8k from both sides.

7k + 20 − 8k = 8k + 16 − 8k

−k + 20 = 16

c) Subtract 20 from both sides.

−k + 20 − 20 = 16 − 20

−k = −4

Divide both sides by -1.

-k/-1 = -4/-1

k = 4

What was the average population decline between 1984 and 2018?
B. The average rate of population decline between 2004 and 2014 is 1.45 thousand deer per year. If the population continued to decline at this rate, between which 2 year period would the population have reached 225 thousand deer? Explain reasoning.

C. Calculate and compare the average rate of change of the population from 1994 to 2004 to that from 2004 to 2014. Explain what this means in terms of the population of deer.

Answers

Using the average rate of change, it is found that:

A. The average population decline between 1984 and 2018 was of 2.25 thousand deer a year.

B. The population would have reached 225 thousand deer between 2017 and 2018.

C.

The rates are as follows:

1994 to 2004: 0.75 thousand deer a year.2004 to 2014: -1.45 thousand deer a year.

Meaning that between 1994 and 2004 there was a increase in the population of deer, and from 2004 to 2014 there was a decrease.

What is the average rate of change of a function?

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:

[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]

For 1984 and 2018, we have that:

f(1984) = 250.f(2018) = 173.50.

Hence the rate is:

r = (173.50 - 250)/(2018 - 1984) = -2.25 thousand deer a year.

For item b, the situation is modeled by a linear function, as follows:

D(t) = 230.50 - 1.45t.

The population would be of 225 thousand deer when D(t) = 225, hence:

230.50 - 1.45t = 225

1.45t = 5.5

t = 5.5/1.45

t = 3.79.

Hence between the years of 2017 and 2018.

For item c, the rates are as follows:

1994 to 2004: (245 - 237.50)/10 = 0.75 thousand deer a year -> increase.2004 to 2014: (230.50 - 245)/10 = -1.45 thousand deer a year -> decrease.

Answers

Using the sample size relation with the standard normal distribution, the required sample size is 3032 samples.

What is Normal distribution ?

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

Using the sample size relation with the standard normal distribution, the required sample size is 673 samples.

n = [(Z* × σ) / ME]²

ME = margin of error

Z* = Z critical at 90% = 1.645

Substituting the values into the equation :

n = [(Z* × σ) / ME]²

n = [(1.645 × 50.2) / 1.5]²

n = (82.6/ 1.5)²

n = 55.06

n ≈ 3032

To find the slope of a line that passes through two points, we can use the following formula:

[tex]\begin{gathered} m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \text{ Where m is the slope and} \\ (x_1,y_1)\text{ and }(x_2,y_2)\text{ are two points which the line passes} \end{gathered}[/tex]

Then, we have:

First pair of lines

Line EF

[tex]\begin{gathered} (x_1,y_1)=E\mleft(-2,3\mright) \\ (x_2,y_2)=F\mleft(6,1\mright) \\ m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{1-3}{6-(-2)} \\ m=\frac{1-3}{6+2} \\ m=\frac{-2}{8} \\ m=\frac{2\cdot-1}{2\cdot4} \\ m=-\frac{1}{4} \end{gathered}[/tex]

Line GH

[tex]\begin{gathered} (x_1,y_1)=G\mleft(6,4\mright) \\ (x_2,y_2)=H\mleft(2,5\mright) \\ m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{5-4}{2-6} \\ m=\frac{1}{-4} \\ m=-\frac{1}{4} \end{gathered}[/tex]

Now, when graphing the two lines, we have:

If two lines have equal slopes, then the lines are parallel. As we can see, their slopes are equal, therefore the lines EF and GH are parallel.

Second pair of lines

Line JK

[tex]\begin{gathered} (x_1,y_1)=J\mleft(4,3\mright) \\ (x_2,y_2)=K\mleft(5,-1\mright) \\ m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{-1-3}{5-4} \\ m=-\frac{4}{1} \\ m=-4 \end{gathered}[/tex]

Line LM

[tex]\begin{gathered} (x_1,y_1)=L\mleft(-2,4\mright) \\ (x_2,y_2)=M\mleft(3,-5\mright) \\ m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{-5-4}{3-(-2)} \\ m=\frac{-9}{3+2} \\ m=\frac{-9}{5} \end{gathered}[/tex]

Now, when graphing the two lines, we have:

As we can see, the slopes of these lines are different, so they are not parallel. Let us see if their respective slopes have the relationship shown below:

[tex]\begin{gathered} m_1=-4 \\ m_2=-\frac{9}{5} \\ m_1=-\frac{1}{m_2} \\ -4\ne-\frac{1}{-\frac{9}{5}} \\ -4\ne-\frac{\frac{1}{1}}{\frac{-9}{5}} \\ -4\ne-\frac{1\cdot5}{1\cdot-9} \\ -4\ne-\frac{5}{-9} \\ -4\ne\frac{5}{9} \end{gathered}[/tex]

Since their respective slopes do not have the relationship shown below, then the lines are not perpendicular.

Third pair of lines

Line NP

[tex]\begin{gathered} (x_1,y_1)=N\mleft(5,-3\mright) \\ (x_2,y_2)=P\mleft(0,4\mright) \\ m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{4-(-3)}{0-5} \\ m=\frac{4+3}{-5} \\ m=-\frac{7}{5} \end{gathered}[/tex]

Line QR

[tex]\begin{gathered} (x_1,y_1)=Q\mleft(-3,-2\mright) \\ (x_2,y_2)=R\mleft(4,3\mright) \\ m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{3-(-2)}{4-(-3)} \\ m=\frac{3+2}{4+3} \\ m=\frac{5}{7} \end{gathered}[/tex]

Now, when graphing the two lines, we have:

Two lines are perpendicular if their slopes have the following relationship:

[tex]\begin{gathered} m_1=-\frac{1}{m_2} \\ \text{ Where }m_1\text{ is the slope of the first line and }m_2\text{ is the slope of the second line} \end{gathered}[/tex]

In this case, we have:

[tex]\begin{gathered} m_1=-\frac{7}{5} \\ m_2=\frac{5}{7} \\ -\frac{7}{5}_{}=-\frac{1}{\frac{5}{7}_{}} \\ -\frac{7}{5}_{}=-\frac{\frac{1}{1}}{\frac{5}{7}_{}} \\ -\frac{7}{5}_{}=-\frac{1\cdot7}{1\cdot5}_{} \\ -\frac{7}{5}_{}=-\frac{7}{5}_{} \end{gathered}[/tex]

Since the slopes of the lines NP and QR satisfy the previous relationship, then this pair of lines are perpendicular.

Fourth pair of lines

Line ST

[tex]\begin{gathered} (x_1,y_1)=S\mleft(0,3\mright) \\ (x_2,y_2)=T\mleft(0,7\mright) \\ m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{7-3_{}}{0-0} \\ m=\frac{4}{0} \\ \text{Undefined slope} \end{gathered}[/tex]

The line ST has an indefinite slope because it is not possible to divide by zero. Lines that have an indefinite slope are vertical.

Line VW

[tex]\begin{gathered} (x_1,y_1)=V\mleft(2,3\mright) \\ (x_2,y_2)=W\mleft(5,3\mright) \\ m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{3-3_{}}{5-2} \\ m=\frac{0}{3} \\ m=0 \end{gathered}[/tex]

Line VW has a slope of 0. Lines that have a slope of 0 are horizontal.

Now, when graphing the two lines, we have:

As we can see in the graph, the ST and VW lines are perpendicular.

x = y + 2

We would plot these equations on the graph. The graph is shown below

The red line represents x = y + 2

The bu line represents x = y + 2

Ariel makes $35 a day. How much can she get for 1/7 of a day? Ariel will earn ____ for 1/7 of the day.

Answers

We can calculate how much she get for 1/7 of a day by multiplying the daily pay rate by 1/7:

[tex]E=\frac{1}{7}\cdot35=\frac{35}{7}=5[/tex]

Answer: Ariel will earn $5 for 1/7 of the day.

Lukalu is rappelling off a cliff. The parametric equations that describe her horizontal and vertical position as a function of time are x ( t ) = 8 t and y ( t ) = − 16 t 2 + 100 and . How long does it take her to reach the ground? How far away from the cliff is she when she lands? Remember to show all of the steps that you use to solve the problem.

Answers

SOLUTION

Now the ground is assumed to be 0, so we have that

[tex]y(t)=0[/tex]

So, that means we have

[tex]\begin{gathered} y(t)=-16t^2+100 \\ 0=-16t^2+100 \\ 16t^2=100 \\ t^2=\frac{100}{16} \\ t=\sqrt{\frac{100}{16}} \\ t=\frac{10}{4} \\ t=2.5\text{ seconds } \end{gathered}[/tex]

Now, we have found t, which is how long it takes to get to the ground, you can plug it into x(t) to find the horizontal distance travelled, we have

[tex]\begin{gathered} x(t)=8t \\ x(2.5)=8\times2.5 \\ =20\text{ feet } \end{gathered}[/tex]

Hence it takes her 2.5 seconds to reach the ground

And she is 20 feet away from the cliff

Describe using words in a sentence the transformations that must be applied to the graph of f to obtain thegraph of g(x) = -2 f(x) + 5.

Answers

we have

f(x)

and

g(x)=-2f(x)+5

so

step 1

First transformation

Reflection about the x-axis

so

f(x) -----> -f(x)

step 2

Second transformation

A vertical dilation with a scale factor of 2

so

-f(x) ------> -2f(x)

step 3

Third transformation

A translation of 5 units up

so

-2f(x) -------> -2f(x)+5

Show all work to identify the asymptotes and state the end behavior of the function f(x) = 6x/ x - 36

Answers

Vertical asymptotes are when the denominator is 0 but the numerator isn't 0.

[tex]x-36=0 \implies x=36[/tex]

Since this value of x does not make the numerator equal to 0, the vertical asymptote is [tex]x=36[/tex].

Horizontal asymptotes are the limits as [tex]x \to \pm \infty[/tex].

[tex]\lim_{x \to \infty} \frac{6x}{x-36}=\lim_{x \to \infty}=\frac{6}{1-\frac{36}{x}}=6\\\\\lim_{x \to -\infty} \frac{6x}{x-36}=\lim_{x \to -\infty}=\frac{6}{1-\frac{36}{x}}=6\\\\[/tex]

So, the horizontal asymptote is [tex]y=6[/tex].

End behavior:

As [tex]x \to \infty, f(x) \to -\infty[/tex]As [tex]x \to -\infty, f(x) \to \infty[/tex].

Rocky Mountain National Park, nicknamed "Rocky," is a true marvel of the American West and contains a variety ofanimals, plant life, and even climates. There are four ecosystems inside Rocky Mountain National Park: riparian, montane,subalpine, and alpine tundra. You might see a moose or mule deer drinking from a pond in a riparian ecosystem, which areareas that are near streams or lakes. Riparian ecosystems can be found within the other three ecosystems. The montaneecosystem is the lowest in elevation at Rocky. There you will find ponderosa pine trees and wide-open mountain meadows,lush with wildflowers in the summer. Climb a little higher into the subalpine ecosystem, where long winters and short, coolsummers make up t the climate. Look high into a limber pine tree and you might spot a Clark's nutcracker, nibbling on pineseeds. Finally, the highest elevation in Rocky is the alpine tundra. Bitter cold and wind-blasted defines this ecosystem with itsjagged mountain tops that are capped with snow even in late August.
