What is the degrees of freedom?

In Mathematics, the degrees of freedom in a sample are typically used to correct a possible bias that exists between the alternative and null hypotheses.

Mathematically, total degrees of freedom for the study can be calculated by using this mathematical expression:

v = n - k

Where:

v represents the total degree of freedom.n represents the number of individuals in a samplek represents the number of parameters being estimated.

Note: k is equal to 2 in this scenario.

Total degrees of freedom, v = n₁ + n₂ - k

Total degrees of freedom, v = 36 + 40 - 2

Total degrees of freedom, v = 74.

The sum of ages of akua and yeboa is 23years akua is 3years older than yeboah fine , the age of yaboah, the product of their ages​

Answers

Answer:

yaboah: 10product: 130

Step-by-step explanation:

Given that akua is 3 years older than yaboah and the sum of their ages is 23, you want the age of yaboah and the product of their ages.

Sum and difference

Let 'a' and 'y' represent the ages of akua and yaboah, respectively. The given relations are ...

  a + y = 23

  a - y = 3

Adding these equations gives ...

  2a = 26

  a = 13

Using this in the second equation, we find ...

  y = a -3 = 13 -3 = 10

Product

The product of their ages is ...

  a·y = 13·10 = 130

Yaboah is 10 and the product of their ages is 130.

what is the correct ordering, from smallest to largest, of the following: $\dfrac{7}{6},$ $\dfrac{17}{15},$ $\dfrac{28}{25}\,?$

Answers

So, the correct ordering from smallest to largest is 17/15, 7/6, 28/25.

When comparing fractions, one way to determine which fraction is larger or smaller is by finding a common denominator and then comparing the numerators. A common denominator is a multiple of both denominators. The least common denominator (LCD) is the smallest common denominator.

In this case, the least common denominator for the fractions 7/6, 17/15, 28/25 is 30.

This is because 30 is the smallest multiple of 6 and 15 that is also a multiple of 25

So, 7/6 = 35/30, 17/15 = 17/15 and 28/25 = 84/75

The numerators of the fractions are 35, 17, and 84 respectively. Since 17 is the smallest numerator and 84 is the largest numerator, we can conclude that 17/15 is the smallest fraction and 84/75 is the largest fraction.

Therefore, the correct ordering from smallest to largest is 17/15, 7/6, 28/25.

In summary, to compare fractions, we can find a common denominator, then compare the numerators. In this case, we used the least common denominator 30, and then compared the numerators 35, 17, 84, which allowed us to order the fractions in an increasing order.

The circumference of the outer circle, greater, 12.57 feet, than the circumference of the inner​ circle.

What is a circle?

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle.

And the general formula of the circle,

(x – h)²+ (y - k)² = r²,

where (h, k) is the center and r is the radius of the circle.

Given:

The circumference of the inner circle is 64 feet.

The radius of the inner circle,

2πr = 64

r = 32 x 7/22

r = 112/11 feet.

The distance between the inner circle and the outer circle is 2 ft.

The radius of the outer circle,

= 112/11 + 2

= 134/11 feet.

The circumference of the outer circle,

= 2 x 22/7 x 134/11

Use the following equation to derive a demand schedule and a demand curve. What types of products might exhibit this type of nonlinear demand curve?

Answers

The equation is as follows: Q = a - bP^2.Nonlinear demand curve like this can be found in luxury goods and Veblen goods. Where the luxury goods are the goods whose demand increases as the price increases and Veblen goods are the goods whose demand increases with an increase in the consumer's income.

The equation is as follows: Q = a - bP^2.

To derive a demand schedule, we can plug in different values of P (price) and solve for Q (quantity demanded). For example:

Q = a - bP^2

Q = a - (b * 10^2)

Q = a - 1000b

Q = a - (b * 9^2)

Q = a - 810b

Q = a - (b * 8^2)

Q = a - 640b

and so on.

To derive a demand curve, we can plot the different points from the demand schedule on a graph, with P on the x-axis and Q on the y-axis. The demand curve will be a downward-sloping parabola.

In how may years ₹ 4,000 will amount to ₹ 14,400 at 10% p.a. Compounded interest payable quarterly ?

Answers

Answer:

P = ₹4,000

F = ₹14,400

r = 10% = 0.10

m = 4 (because interest is compounded quarterly)

So, we can plug in these values into the formula:

n = (log(14400 / 4000)) / (log(1 + 0.10 / 4))

n = (log(3.6)) / (log(1.025))

n = 2.59

Therefore, it will take approximately 2.59 years for the investment of ₹4,000 to grow to ₹14,400 at a 10% annual interest rate compounded quarterly.

Oliver read for 450450450 minutes this month. His goal is to read for 10\%10%10, percent more minutes next month.
If Oliver meets his goal, how many minutes will he read in all during the two months?

Answers

Using percentages we know that he read for 945 minutes over two months, covering pages. If Oliver accomplishes his goal of reading for 19% more minutes next month.

What is the percentage?

Since one percent (symbolized as 1%) is equal to one-hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.

As an illustration, 1% of 1,000 chickens is equal to 1/100 of 1,000, or 10 birds, and 20% of the quantity is equal to 20% of 1,000, or 200.

So, this month, Oliver read for 450 minutes.

He has promised to read for 10% extra minutes the following month.

Next month, he spent minutes reading pages:

450 + 10% * 450 = 450 + 45 = 945

He, therefore, read for pages at a time for two months = 450+495=945

Hence He read for 945 minutes over two months, covering pages.

Based on the graph, how many students in a class of 360 students would be expected to choose hip-hop or rock as their favorite type of music?

Answers

Number of students who are expected to choose hip hop or rock as their favorite type of music is 240.

What is Percentage?

Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.

So the percentage actually means a part per 100.

Percentage is usually denoted by the symbol '%'.

From the graph,

Number of students who choose rock music = 20

Number of students who choose hip hop music = 40

Number of students who choose country music = 30

Total number of students = 20 + 40 + 30 = 90

Percentage of students who choose rock or hip hop = (20+ 40) / 90

                                                                                        = (60 / 90)

                                                                                        = 66.67%

Out of 360 students, 66.67% of students will chose hip hop or rock.

The number of papers ms. Motley grades increases exponentially as
time goes on. On the first day she grades 9 papers , on the second day she grades 27 papers and on the third day she grades 31 papers

How many will she grade in five days?

After many days will it take her to grade 6,000 papers?

Answers

The papers graded exponentially at the end of 5 days are 134, and it will take approximately around 12 days to complete 6000 papers.

What is exponential function?

A function is considered to be exponentially growing if its value rises faster than any polynomial. The function e^x, serves as a good illustration.

The exponential growth is given by the following formula:

[tex]A = Pe^{rt}[/tex]

where, A is the final amount, P is the initial amount, r is the rate and t is the time.

For t = 0, the number of papers graded are, 9, hence the value of P = 9.

To calculate the rate at which the work is done, substitute the value of P = 9, A = 27 and t = 2 in the equation:

[tex]27 = 9 e^{2r}\\3 = e^{2r}[/tex]

Taking ln on both sides of the equation:

[tex]ln (3) = ln(e^{2r})\\\\ln(3) = 2r[/tex]

1.09 = 2r

r = 0.54

To calculate the number of papers graded in five days, substitute the value of P = 9, t = 5 and r = 0.54.

[tex]A = 9 e^{(0.54)(5)}[/tex]

A = 134

Hence, the papers graded at the end of 5 days are 134.

To complete grading 6000 papers, the time taken will be:

6000 = 9e^(0.54)(t)

666.66 = e^(0.54)(t)

Taking ln on both sides of the equation:

ln (666.66) = ln(e^(0.54)(t))

6.50 = (0.54)(t)

t = 12.04

Hence, it will take approximately around 12 days to complete 6000 papers.

What is trigonometry?

The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.

The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.

Given that at a given point of 67.7ft at the ground level of a covered court, the angle of elevation of a roof worker from the bottom is 38.6⁰ and the angle of elevation of the roof from the top is 42.4 degrees.

The base will be calculated as:-

tan(38.6) = P / B

tan(38.6) = 67.7 / B

B = 67.7 / tan(38.6)

B = 54.8 ft

The height will be calculated as:-

Cos(42.4) = B / H

H = 84.8 / Cos(42.4)

H = 114.83 ft

Therefore, If someone were to look down from above, they would be 114.83 feet from the object and 84.8 feet away.

When interpreting a research question and statistical results, a natural question arises as to whether the finding could have occurred by chance. Hypothesis testing is a statistical procedure for testing whether chance (random events) is a reasonable explanation of an experimental finding.

In hypothesis testing, we will always set up a particular hypothesis that we want to demonstrate to be true. We then use probability to determine the likelihood of our hypothesis is correct. If it appears our original hypothesis was wrong, we reject it and accept the alternative hypothesis. The alternative hypothesis is usually the opposite of our original hypothesis. In Fisher’s case, his original hypothesis was that the lady was guessing. His alternative hypothesis was the lady was not guessing.

Generally speaking, the hypotheses that business researchers want to prove are stated in the alternative hypothesis.

Thus, the statement 'In testing hypotheses, the researcher initially assumes that the alternative hypothesis is true and uses the sample data to reject it' is False.

The equation of the linear function in this problem is given as follows:

y = 0.5x + 4.

How to define the linear function?


The slope-intercept definition of a linear function is given as follows:

y = mx + b.

In which:

The slope m represents the rate of change.The intercept b represents the value of y when x = 0.

When x = 0, y = 4, hence the intercept b is given as follows:

b = 4.

When x increases by 8, y increases by 4, hence the slope m is given as follows:

m = 4/8 = 0.5.

Missing Information

The linear function goes through the points (-8,0) and (0,4).

A card is drawn at random from a standard pack of playing cards.
Then a fair coin is flipped.
What is the probability of selecting a 9 and the coin landing on tails?

Answers

The probability of selecting a 9 and the coin landing on tails is 1/26.

What is the probability?

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes

Here,

The probability of selecting a card 9 is

Total number of outcomes =52

Number of favourable outcomes =4

Now, probability = 4/52

= 1/13

The probability of coin landing on tails is

1/2

Probability of an event = 1/13 × 1/2

= 1/26

Therefore, the probability of selecting a 9 and the coin landing on tails is 1/26.

Find the break-even point for the given cost and revenue equations. Round to the nearest whole unit.
C = 20n + 134,000
R = 160n

Answers

Answer:

in break-even point

C=R

20n+134000=160n

134000= 160n-20n

140n=134000

n=134000/140

n=957.14

n=957 ( nearest whole number)

C= 20(957.14) + 134000

= 153142.8

= 153143 (nearest whole number)

R= 160(957.14)

=153142.4

An oil company purchased an option on land in Alaska. Preliminary geologic studies assigned the following prior probabilities.
P(high-quality oil)=0.45
p(medium-quality oil)=0.15
p(no oil)=0.40
a. What is the probability of finding oil (to 2 decimals)?
b. After 200 feet of drilling on the first well, a soil test is taken. The probabilities of finding the particular type of soil identified by the test are given below.
p(soil | high-quality oil)=0.15
p(soil | medium-quality oil)= 0.75
P(soil | no oil)=0.15
Given the soil found in the test, use Bayes' theorem to compute the following revised probabilities (to 4 decimals).
What is the new probability of finding oil (to 4 decimals)?
According to the revised probabilities, what is the quality of oil that is most likely to be found?

Answers

The total probability of filling oil is 0.60

a. P(oil) = 1 - P(no oil) = 1 - 0.40 = 0.60

b.P(soil ∩ high quality oil) = (0.45)(0.15) = 0.067

P(soil ∩ medium quality oil) = (0.15)(0.15) = 0.022

P(soil ∩ no oil) = (0.40)(0.40) = 0.16

New probabilities,

P(high quality oil | soil) = 0.067 / (0.067+0.022+0.16) = 0.067/0.269 = 0.269

P(medium quality oil | soil) = 0.022 / (0.067+0.022+0.16)  = 0.022/0.269 = 0.088

P(no oil | soil) = 0.09 / (0.067+0.022+0.16) = 0.09/0.269 = 0.361

New probability of finding oil,

P(oil|soil)= 1 - P(no oil | soil) = 1 - 0.361 = 0.639

So the company has a lower chance of finding oil given that they find the particular soil.

In order to determine whether this horizontal position of the pumpkin trajectory represents a minimum or maximum, evaluate at Im. View Available Hint(s) dy a = -8.0 x 10-3m (negative, so this is a minimum) d=2a = –16 x 10-3 (negative, so this is a minimum) ay=2a = -16 x 10-4 (negative, so this is a maximum) = -8.0 x 10m (negative, so this is a maximum)

Answers

A projectile have a minimum speed at the highest point of its trajectory. This is because horizontal speed of the projectile remains constant.

Since the only force exerted on the projectile is gravity, which is

9.8 ms ^2  acting downwards and has no effects on the horizontal velocity.The maximum height the pumpkin reaches occurs at 62.5 horizontal meters from its launching spot.

The calculation is as follows;

The equation is y = -0.008x^2 +x

that corresponds to a curve presented by a parabola.

Now we can determine the maximum of this parabola with arms pointing down requesting the derivative slope of the tangent line to

the curve to be zero

Answers

The situation that can be described as dependent events is c.) Renata randomly chooses a chocolate chip cookie from a cookie jar. She eats the cookie and chooses again. This time she gets a sugar cookie.

What are dependent events ?

Events that are dependent upon prior events are called dependent events. The results of earlier events have an impact on these current ones. For example, two or more occurrences that are interdependent are referred to as dependent events. An event generally qualifies as being reliant if it offers details about another event. If an event provides no information about other events, it is considered independent.

The dependent event would be Renata picking a sugar cookie the second time she chooses another cookie because she ate from the first cookie and so was able to avoid it the second time.
