n a study of academic procrastination, it was determined that for a random sample of 18 undergrad students at a mid-size public university, the mean time spent studying for the final exam in an intro statistics course was 7.74 hours with a standard deviation of 3.40 hours. Suppose we wish to compute a 95% confidence interval for the mean time spent studying for the intro statistics final exam by all students. The margin of error for this confidence interval would then be calculated using the critical value (c) determined in the previous question as: (Don't worry if your sample size changed- use the one given here).

Answers

Answer 1

Answer:

The 95% confidence interval for the mean time spent studying for the intro statistics final exam by all students is between 6.05 hours and 9.84 hours.

Step-by-step explanation:

We have the standard deviation for the sample, which meas that the t-distribution is used to solve this question

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 18 - 1 = 17

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 17 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 2.11

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 2.11\frac{3.4}{\sqrt{18}} = 1.69[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 7.74 - 1.69 = 6.05 hours

The upper end of the interval is the sample mean added to M. So it is 7.74 + 1.69 = 9.84 hours.

The 95% confidence interval for the mean time spent studying for the intro statistics final exam by all students is between 6.05 hours and 9.84 hours.

How to solve projectile equations?

We are given the function;

h = -(500/9)t² + (1000/3)t + 10

where;

h is height after time of t seconds

At height of zero, the firework would either be about to launch or when it has come down.

Thus, let us set h = 0 to find the times.

0 = -(500/9)t² + (1000/3)t + 10

Using quadratic equation calculator, we have;

t ≈ 2 seconds

Now the  firework explodes at the highest point which will be the mid point of where the launching started and the endpoint where it stopped.

This means time at midpoint = (0 + 2)/2 = 1 sec

It explodes after 1 second.

Thus maximum height at this time is;

h = -(500/9)(1)² + (1000/3)(1) + 10

The measure of the largest exterior angle of the triangle will be 162°.

What is the triangle?

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.

The exterior angles of the triangle are 3x°, 8x°, and 9x°. Then the measure of the interior angle of the triangle will be 180° - 3x°, 180° - 8x°, and 180° - 9x°.

The sum of the interior angle of the triangle is 180°. Then the equation is given as,

180° - 3x° + 180° - 8x° + 180° - 9x° = 180°

Find the point on the line 3x + y = 8 that is closest to the point
(−3, 1)

Answers

The point on the line 3x + y = 8 that is closest to the point (-3, 1) is (1.8, 2.6).

What is Quadratic Equations?

Quadratic equations are equations of the form a x² + b x + c = 0 where a, b and c are real numbers.

Given line is,

3x + y = 8 ⇒ y = -3x + 8

So we have any point (x, -3x + 8).

We have to find a point (x, -3x + 8) such that distance of this point from (-3, 1) is minimum.

Distance between (-3, 1) and (x, -3x + 8) = √[(x - -3)² + (-3x + 8 - 1)²]

                                                                  = √[(x + 3)² + (-3x + 7)²]

                                                                  = √(x² + 6x + 9 + 9x² - 42x + 49)

                                                                  = √(10x² - 36x + 58)

So the distance between (-3, 1) and (x, -3x + 8) is √(10x² - 36x + 58) should be minimum.

We minimize the function f(x) = 10x² - 36x + 58.

A quadratic function represents the equation of a parabola.

Coefficient of x² is positive, so parabola opens upward. So we will be having the minimum value.

Minimum value at the point x = -b / 2a for the quadratic equation a x² + b x + c.

Minimum value is at x = - (-36) / (2 × 10) = 36/20 = 9/5 = 1.8.

To find the y coordinate,

y = -3x + 8 = 2.6

So the required point is (1.8, 2.6).

Hence the point on the line closest to the point (-3, 1) is (1.8, 2.6)

Determine if the following equation has one, none, or many solutions.
2(2x+-1)=4x-4

Answers

To determine whether an equation has one, none, or many solutions, we need to solve the equation for the variable. In the case of the equation 2(2x+-1)=4x-4, we can solve for x by first distributing the 2 on the left-hand side of the equation:

22x+2-1 = 4x - 4

This gives us the following equation:

4x-2 = 4x - 4

We can then subtract 4x from both sides of the equation to obtain:

-2 = -4

This equation does not have any solutions, because the left-hand side and the right-hand side are not equal. Therefore, the original equation has no solutions.

Answers

The Equation of line is y= 16.1x + 210. 8.

The approximate price by 2025 is 452.3.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

The points are (1, 226.9) and (4, 275.2).

So, Slope for line

m = ( 275.2- 226.9)/( 4-1)

m = 48.3/ 3

m= 16.1

Now, using the slope- intercept form

y= mx+ b

y = 16.1x + b

Now, x= 1 and y= 226.9

By, y = 16.1 + x

226.9 = 16.1(1)+ b

b= 210.8

So, the equation of line is y= 16.1x + 210. 8

Now,  x is the number of years since 2010 and by 2025

x= 2025 - 2010 = 15

Then, the approximate price by 2025

y= 16.1(15) + 210.8

y= 452.3

Hence, the approximate price by 2025 is 452.3.

     $1526.49:  10 yr

(b)  See below.

(c)  x = 705

Step-by-step explanation:

Given equation:

[tex]t=16.708 \ln \left(\dfrac{x}{x-705}\right)[/tex]

where:

t = term of the mortgage (in years)x = monthly payment plan (in dollars)

Part (a)

[tex]\begin{aligned}x=897.72 \implies t& =16.708 \ln \left(\dfrac{897.72}{897.72-705}\right)\\& =16.708 \ln \left(4.65815691...\right)\\&=16.708(1.53861985...)\\&=25.70726...\\&=26\; \rm years\end{aligned}[/tex]

[tex]\begin{aligned}x=1526.49 \implies t& =16.708 \ln \left(\dfrac{1526.49}{1526.49-705}\right)\\& =16.708 \ln \left(1.85819669...\right)\\& =16.708(0.619606496...)\\&=10.352385...\\&=10 \; \rm years\end{aligned}[/tex]

Part (b)

To approximate the total amounts paid (in dollars) over the term of the mortgage, multiply the monthly payment by the term.

Please note I have provided two calculations per monthly payment:

(1) by using the exact term, and (2) using the rounded term from part (a).

[tex]\implies \$897.72 \times 25.7072605... \times 12 =\$276935.06[/tex]

[tex]\implies \$897.72 \times 26 \times 12=\$280088.64[/tex]

[tex]\implies \$1526.49 \times 10.3523853... \times 12=\$189633.75[/tex]

[tex]\implies \$1526.49 \times 10 \times 12 =\$183178.80[/tex]

To calculate the amount of interest costs (in dollars) in each case, subtract $150,000 from the total amounts paid:

[tex]\$897.72\implies 276935.06-150000=\$126935.06[/tex]

[tex]\$897.72 \implies 280088.64-150000=\$130088.64[/tex]

[tex]\$1526.49 \implies 189633.75-150000=\$39633.75[/tex]

[tex]\$1526.49\implies 183178.80-150000=\$33178.80[/tex]

Part (c)

The natural logarithm of a negative number cannot be taken.

Therefore, x > 705.

So the vertical asymptote for the model is:

x = 705

The monthly payment must be more than $705, and the closer to this value the payment is, the longer it will take to pay off the mortgage.

No, A is not defective.

What is the rank nullity theorem?    

The rank–nullity theorem is a theorem in linear algebra, which asserts that the dimension of the domain of a linear map is the sum of its rank (the dimension of its image) and its nullity (the dimension of its kernel).

Given here  A be a 4 x 4 matrix and let λ be an eigenvalue of multiplicity 3 and rank 1, then by rank nullity theorem we have

    Rank(A-λI) + Nullity((A-λI) =4

⇒dimN(N-λI) = Nullity(A-λI)

⇒dimN(N-λI) = 4 - Rank(A-λI)

⇒dimN(N-λI)  = 4-1

⇒dimN(N-λI) = 3

Therefore 3 linearly independent eigenvectors belong to eigenvalue λ. Since λ is an eigenvalue of multiplicity 3, this ensures that there is a different eigenvalue different from λ. Along with 3 linearly independent eigenvectors in the eigenspace of λ, this gives us 4 linearly independent eigenvectors in the matrix A. Now we An n × n matrix A is diagonalizable if and only if A has n linearly independent eigenvectors. Thus A is nondefective

Hence, matrix A is not defective.

Write the equation for each function and determine how many students would be in each high school in the year they are projected to have the same number of students. A(t) = B(t) =

Answers

Answer:

1. A(t) = 65t + 700

2.B(t) = 40t + 900

3. High School A and High School B will both have 1,220 students in the 8th year

Step-by-step explanation:

1. The equation for the number of students in High School A represents a linear function.

⭐ What is a linear function?

A linear function is a type of equation where every y-value increases by a constant, additive amountOne way to write the equation for a linear function is: [tex]y = mx+b[/tex], where m is the constant, additive amount, and b is the y-intercept, or the initial value.

Let's write the equation for High School A in the [tex]y = mx+b[/tex] format, known as slope-intercept form:

The constant, additive amount for High School A is 65 (m)The initial value for High School A is 700 (b)

∴ High School A: [tex]y = 65x + 700[/tex]

2. Let's write the equation for High School B in the [tex]y = mx + b[/tex] format, known as slope-intercept form:

The constant, additive amount for High School B is 40 (m)The initial value for High School B is 900 (b)

∴ High School B: [tex]y = 40x + 900[/tex]

3. To find at what year High School A and High School B will have the same number of students, we need to solve a system of linear equations.

What is a system of linear equations?

A system of linear equations is two or more linear equations that intersect at one point (x,y)

For this problem, let's set both linear equations equal to each other to see at what point will the high school populations be the same.

[tex]A(t) = B(t)[/tex]

[tex]65t + 700 = 40t + 900[/tex]

[tex]25t = 200[/tex]

[tex]t = 8[/tex]

Now we know that in the 8th year, High School A will have the same population as High School B.

We need to find what the population will be in year 8.

Thus, substitute the value of t into one of the functions and solve.

I am choosing to substitute t into A(t), but you can also do B(t).

[tex]A(8) = 65(8) + 700[/tex]

[tex]A(8) = 520 + 700[/tex]

[tex]A(8) = 1,220[/tex]

⚠️!!! CAUTION !!! ⚠️

Some people may stop at this point and write that in the 8th year, both high schools will have a population of 1,220 students.

However, you should also substitute 8 into the other function you didn't substitute it into to make sure that 8 is correct.

[tex]B(8) = 40(8) + 900[/tex]

[tex]B(8) = 320 + 900[/tex]

[tex]B(8) = 1,220[/tex]

∴ In the 8th year, both high schools will have a population of 1,220 students.

What is the solution of the system? Use elimination.
3x +9y=33
-10x-6y=-14
a. (-4,5)
b. (4,-1)
c. (-10, 3)
d. (-1,4)

Answers

To solve the given system of equations using elimination, we can add the two equations together to eliminate one of the variables. Doing this, we get 3x + 9y + (-10x - 6y) = 33 + (-14), which simplifies to -7x + 3y = 19. We can then solve for y by dividing both sides of the equation by 3, giving us y = 19/3 = 6.33. We can substitute this value for y in either of the original equations to solve for x. For example, if we substitute 6.33 for y in the first equation, we get 3x + 9 * 6.33 = 33, which simplifies to 3x = 3.67. Dividing both sides of the equation by 3, we get x = 1.22. Therefore, the solution of the system is (1.22, 6.33), which is approximately (1, 6). The answer choice that is closest to this solution is (d) (-1, 4). Thus, the solution of the system is (-1, 4).

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given that Image of polygon ABCD and a second polygon A prime B prime C prime D prime to the right.

ABCD is the original image and  prime B prime C prime D prime is the transformed image.

ABCD rectangle is transformed to A'B'C'D'.

As we observe the diagram, the two rectangles look the same which means the shape remains constant.

The translation is applied to the original image which move to the right side.

A translation is a movement of the graph either horizontally parallel to the x axis or vertically parallel to the y axis.

We can reflect the graph of any function f about the x-axis by graphing y=-f(x) and we can reflect it about the y-axis by graphing y=f(-x).

Hence, Reflection across the y-axis is the transformation used to the polygon ABCD.

Rain is flowing into 2 containers at different rates. The figure below shows the volume of water in each container what is the difference in rate of change between the two containers

Answers

With the help of Linear relationships The difference in the rate of change between the two containers is 1/5 gallon per minute.

what is Linear relationships?

A statistical word used to express a straight-line relationship between two variables is a linear relationship (or linear association). Graphs and mathematical equations of the form y = mx + b can both be used to represent linear relationships. In everyday life, linear relationships are quite prevalent.

Given:

Volume of water in each container.

To find:

Difference in the rate of change.

Solution:

Take any two points on container 1.

Let the points are (10, 2) and (20, 4).

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

   = ( 4 - 2 ) / ( 20 - 10 )

   = 2/ 10

   = 1/ 5

Rate of change for container 1 is .

Take any two points on container 2.

Let the points are (5, 2) and (10, 4).

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

   = ( 4 - 2 ) / ( 10 - 5)

   = 2 / 5

Rate of change for container 2 is 2/5

Difference = (2 /5 ) - ( 1/ 5 )

                  = 1 / 5  

Hence, The difference in the rate of change between the two containers is 1/5 gallon per minute.
