Rachel is conducting a study in her cognitive psychology lab about people's ability to remember rhythms. She played a short Rhythm to 425 randomly chosen people. One minute later, she asked him to repeat it by clapping. If 121 people were able to successfully reproduce the rhythm, estimate the proportion of the population (including the margin of error) that would be able to successfully reproduce the rhythm. Use a 95% confidence interval.

Answers

Answer 1

Given:

Sample Size (n) = 425

No. of Success = 121

Find: estimate the proportion of the population

Solution:

Let's calculate first the success proportion in the sample by dividing no. of success over the total number of people then multiply it by 100.

[tex]\frac{121}{425}\times100\%=28.47\%[/tex]

Our sample proportion p = 28.47%.

Then, for the margin of error, the formula is:

[tex]MOE=z\sqrt{\frac{p(1-p)}{n}}[/tex]

where z = critical value, p = sample proportion, and n = sample size.

For our z-value, since we are using a 95% confidence interval, the value of z = 1.645.

[tex]MOE=1.645\sqrt{\frac{.2847(1-.2847)}{425}}[/tex]

Then, solve.

[tex]MOE=1.645\sqrt{\frac{0.203648}{425}}[/tex][tex]MOE=1.645(0.02189)[/tex][tex]MOE=0.036[/tex]

Let's multiply the MOE by 100%.

[tex]0.036\times100\%=3.6\%[/tex]

Therefore, about 28.47% ± 3.6% or between 24.87% to 32.07% of the population would be able to successfully reproduce the rhythm.

Given, a library has 144 books. A long shelf can fit 100 books. A short shelf can fit 10 books.

The books that are left over can be put in a bin.

Now, we have to find the way to sort the books on a shelf.

So, we can put the books in this fashion,

100 books can be kept in the long shelf and the 10 books can be kept in the short shelf.

The remaining 34 books can be kept in the bin.

Hence, 100 books can be kept in the long shelf and the 10 books can be kept in the short shelf.

Answers

Which triangles are similar?

The triangle AED and the triangle ABC is similar.

How do you know?

Because all the angles are equal, the triangle AED and ABC have the same angle values, then they're similar.

Find the height of the tree (This distance from B to C)

We can use the relation of the similar triangle to find BC, we can write the equation

[tex]\frac{AB}{AD}=\frac{BC}{ED}[/tex]

The only unknown value here is BC, then

[tex]\frac{24+8}{8}=\frac{\text{BC}}{5}[/tex]

Now we solve it for BC!

[tex]\begin{gathered} \frac{32}{8}=\frac{BC}{5} \\ \\ 4=\frac{BC}{5} \\ \\ BC=4\cdot5 \\ \\ BC=20\text{ ft} \end{gathered}[/tex]

Hence, the height of the tree is 20 ft

The center of a circle and a point on the circle are given. Writecenter: (3,2), point on the circle: (4,3)

Answers

Given:

The center of the circle is the point ( 3, 2 )

And the point on the circle is ( 4, 3 )

To write the equation of the circle, we need to find the radius

The radius = the distance between the center and the point on the circle

so, the radius is the distance between ( 3, 2) and ( 4, 3)

So,

[tex]\begin{gathered} r=d=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2} \\ r=\sqrt[]{(4-3)^2+(3-2)^2^{}}=\sqrt[]{1+1}=\sqrt[]{2} \end{gathered}[/tex]

The general equation of the circle is:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where (h, k) is the coordinates of the center of the circle, r is the radius

So,

[tex]\begin{gathered} (h,k)=(3,2) \\ r=\sqrt[]{2} \end{gathered}[/tex]

so, the equation of the circle will be:

CJ loves Girl Scout cookies. He eats 3 cookies per hour. After 5 hours, there are 24 cookies left in the box. Write an equation in slope intercept form. Determine how many hours it will take CJ to eat the entire box of cookies.

Answers

To solve this problem: y will represent the number of cookies, and x the number of hours.

To find the number of cookies that CJ eats per hour, we multiply 3 (since he eats 3 per hour) by x (the number of hours)

Since there we only 24 cookies left in the box, we will need to substract 3 by the number of hours that have passed, from 24 to find the number of cookies "y":

[tex]y=24-3(x-5)[/tex]

This equation represents that the number of cookies "y" is equal to the 24 cookies that where left after 5 hours, and to that we substract 3 (which is the number of cookies per hour) by total number of hours that have passed since those 5 hours (x-5) because 5 hours that have already passed we substract them from x.

We need to simplify that equation to represent in slope-intercept form:

[tex]\begin{gathered} y=24-3x+15 \\ y=-3x+39 \end{gathered}[/tex]

Now we need to determine the number of hours it would take to finish the cookies. So we are looking for the value of x, that makes y=0:

[tex]0=-3x+39[/tex]

solving for the number of hours x:

[tex]\begin{gathered} -3x=-39 \\ x=-\frac{39}{(-3)} \\ x=13 \end{gathered}[/tex]

It would take 13 hours for CJ to eat the entire box of cookies.

Solve the equation for X. Round the answer to three decimal places. 4^x = 6

Triangles ABE, ADE, and CBE are shown on the coordinate grid, and all the vertices have coordinates that are integers. Which statement is true?

Answers

To check if Triangles ABE, ADE, and CBE are congruent, let us compute for the distance of each line using the Distance Formula,

[tex]\text{ }d\text{ = }\sqrt[]{(x_2-x_1)^2\text{ + (}y_2-y_1)^2}[/tex]

Where,

d = Distance

(x1, y1) = Coordinates of the first point

(x2, y2) = Coordinates of the second point

Let's compute the distance of the following lines:

Triangle ABE: Lines AB, AE, and BE

Triangle ADE: Lines AD, AE, and ED

Triangle CBE: Lines CE, CB, and BE

For Triangle ABE,

[tex]\text{ d}_{AB}\text{ = }\sqrt[]{(-1-(-4))^2+(3-(-1))^2}\text{ = }\sqrt[]{(-1+4)^2+(3+1)^2}[/tex][tex]\text{ d}_{AB}\text{ = }\sqrt[]{(3)^2+(4)^2}\text{ = }\sqrt[]{9+\text{ 16}}\text{ = }\sqrt[]{25}[/tex][tex]\text{ d}_{AB}\text{ = 5}[/tex][tex]\text{ d}_{AE}\text{ =}\sqrt[]{(1-\text{ }(-1))^2+(0\text{ - }(-4))^2}\text{ = }\sqrt[]{(1+1)^2+(0+4)^2}[/tex][tex]\text{ d}_{AE}\text{ = }\sqrt[]{(2)^2+(4)^2}\text{ = }\sqrt[]{4\text{ + 16}}[/tex][tex]\text{ d}_{AE}\text{ =}\sqrt[]{20}[/tex][tex]\text{ d}_{BE}\text{ = }\sqrt[]{(1\text{ - (}3))^2+(0\text{ - (-1)})^2}\text{ = }\sqrt[]{(1-3)^2+(0+1)^2}[/tex][tex]\text{ d}_{BE}=\text{ }\sqrt[]{(-2)^2+(1)^2}\text{ = }\sqrt[]{4\text{ + 1}}[/tex][tex]\text{ d}_{BE}\text{ = }\sqrt[]{5}[/tex]

For Triangle ADE, let's compute for the distance of line AD and ED since we already got the distance of line AE.

[tex]\text{ d}_{AD}\text{ = }\sqrt[]{(-1-(-1))^2+\text{ (}1\text{ - }(-4))^2}\text{ = }\sqrt[]{(-1+1)^2+(1+4)^2}[/tex][tex]\text{ d}_{AD}\text{ = }\sqrt[]{(0)^2+(5)^2}\text{ = }\sqrt[]{25}[/tex][tex]\text{ d}_{AD}\text{ = 5}[/tex][tex]\text{ d}_{ED}=\text{ }\sqrt[]{(-1\text{ - (}1))^2+(1-0)^2}\text{ = }\sqrt[]{(-1-1)^2+(1)^2}[/tex][tex]\text{ d}_{ED}\text{ = }\sqrt[]{(-2)^2_{}+(1)^2}\text{ = }\sqrt[]{4\text{ + 1}}[/tex][tex]\text{ d}_{ED}\text{ = }\sqrt[]{5}[/tex]

For Triangle CBE, let's compute for the distance of line CE and CB since we already got the distance of line BE.

[tex]\text{ d}_{CE}\text{ = }\sqrt[]{(3-\text{ }1)^2+(4-0)^2}\text{ = }\sqrt[]{(2)^2+(4)^2}[/tex][tex]\text{ d}_{CE}\text{ = }\sqrt[]{4+16}\text{ = }\sqrt[]{20}[/tex][tex]\text{ d}_{CE}\text{ = }\sqrt[]{20}[/tex][tex]\text{ d}_{CB}\text{ = }\sqrt[]{(3-3)^2+(4\text{ - (}-1))^2}\text{ =}\sqrt[]{(0)^2+(4+1)^2}[/tex][tex]\text{ d}_{CB}\text{ =}\sqrt[]{(5)^2}\text{ = }\sqrt[]{25}[/tex][tex]\text{ d}_{CB}\text{ = 5}[/tex]

In summary,

Triangle ABE:

[tex]AB=\text{ 5, AE = }\sqrt[]{20}\text{ and BE = }\sqrt[]{5}[/tex]

Triangle ADE:

[tex]\text{ AD = 5, AE = }\sqrt[]{20}\text{ and ED = }\sqrt[]{5}[/tex]

Triangle CBE: CE, CB, and BE

[tex]\text{ CB = 5, CE = }\sqrt[]{20}\text{ and BE = }\sqrt[]{5}[/tex]

The sides of the three triangles shown in the grid are congruent based on the SSS Rule of Triangle.

Thus, the statement that meets our evaluation is:

D. Triangle ABE, ADE and CBE are all congruent.

Answers

For this problem, we were provided with the graph of a quadratic equation, and we need to determine the solutions for this graph.

The solutions of a quadratic equation are the values of "x" that make the expression equal to "0". Therefore, we need to look at the graph for the values at which the graph crosses "y=0".

We have two points for this problem. The first one is approximately -5, and the second is 6.
