Which of the following polynomial expressions did you f​

Answer:

Step-by-step explanation:

rate of change or slope is 1/2.

The equation of a line is y = mx + b, m is the slope.

when x is -2, y is 5.

5 = (1/2)*(-2)+b

b = 6

The equation y = x/2 + 6

Answer:

x = -1 ± √6 / 5

Step-by-step explanation:

Solve \(5x^{2}\) + 2x = 1

move 1 to the left side of the equation by subtracting it from both sides.

\(5x^{2}\) + 2x - 1 = 0

Use the quadratic formula to find the solutions.

-b± \(\sqrt{b^2 - 4 (ac)}\)/ 2a

Substitute the values a = 5 , b = 2, and c = -1 into the quadratic formula and solve for x

-2±\(\sqrt{2^2 - 4(5 - 1)}\)/ 2 ⋅ 5

Simplify.

x = -2 ± 2 \(\sqrt{6}\)/ 10

x = -1 ± \(\sqrt{6}\)/ 5

Exact Form:

x = -1 ± \(\sqrt{6}\)/ 5

The limits from both sides are different, the limit does not exist. Therefore, the answer is DNE.

To evaluate the given limit:

lim t→7 (t² - 4t - 21) / (t - 7)

We first notice that the denominator becomes zero as t approaches 7, which means the function is not defined at t=7. We must check whether there is a limit from both sides of 7.

Let's approach the limit from the left side of 7. We substitute t=7 - h, where h is a positive number approaching zero.

lim h→0- [(7 - h)² - 4(7 - h) - 21] / [(7 - h) - 7]

= lim h→0- [49 - 14h + h² - 28 + 4h - 21] / (-h)

= lim h→0- (-h² - 10h) / (-h)

= lim h→0- (h² + 10h) / h

= lim h→0- (h + 10) = -10

Now, let's approach the limit from the right side of 7. We substitute t=7 + k, where k is a positive number approaching zero.

lim k→0+ [(7 + k)² - 4(7 + k) - 21] / [(7 + k) - 7]

= lim k→0+ [49 + 14k + k² - 28 - 4k - 21] / k

= lim k→0+ (k² + 10k) / k

= lim k→0+ (k + 10) = 10

Since the limits from both sides are different, the limit does not exist. Therefore, the answer is DNE.

Generally, the equation for the probability is  mathematically given as

P(X > 100.6) = P(X-mean)/sd > (100.6-98.18)/0.64 )

P(X > 100.6)= P(Z > 3.7813)

P(X > 100.6)= 1 - P(Z < 3.7812)

P(X > 100.6)= 1 - 0.9999

P(X > 100.6)= 0.0001

Based on the likelihood presented before, the proportion of normal functioning and healthy people who may be regarded to have a fever is 100% multiplied by 0.00001, which is 0.01%.

This proportion has no bearing on the statistical picture at all. Therefore, this temperature cannot possibly be accurate since it is so absurdly high.

Answer:

(3, 9 )

Step-by-step explanation:

x + y = 12 → (1)

y = 3x → (2)

substitute y = 3x into (1)

x + 3x = 12

4x = 12 ( divide both sides by 4 )

x = 3

substitute x = 3 into (2) and solve for y

y = 3x = 3 × 3 = 9

solution is (3, 9 )

a. The monthly payment for this vehicle using the formula is $576.63

b. The 1st payment goes toward interest is $466.98

c. The 48th payment goes toward interest is $12,011.84

d. The remaining balance on the loan at the end of the 3rd year is $12,011.84

e. Principal repayment in the fourth year is $6,719.16

a) We can use the loan formula for finding the monthly payment. i= 5% / 12 = 0.0041666666666667n = 4 × 12 = 48PV = 29815 - 3500 = 26315 PMT = PV × i / (1 - (1 + i)-n)= $576.63 per month

b) For the first payment, the interest is calculated on the outstanding principal balance (OPB). Principal part of first payment = PMT - Interest part

Interest part for the first payment = OPB × i= 26315 × 0.0041666666666667= $109.65Principal part for the first payment = PMT - Interest part= $576.63 - $109.65= $466.98

c) As it is a reducing balance loan, the outstanding principal balance (OPB) at the end of 47 months = OPB at the end of 48th month

d) Outstanding principal balance (OPB) at the end of the 3rd year = PV × (1 + i)^(n÷12) - [PMT × ((1 + i)^(n÷12) - 1) ÷ i]OPB at the end of 3 years = 26315 × (1 + 0.0041666666666667)^(36) - [576.63 × ((1 + 0.0041666666666667)^(36) - 1) ÷ 0.0041666666666667]= $12,011.84

e) In the first year, only 12 payments are made. Let us calculate the interest and principal part of these payments separately and add them up to find the totals. Principal repayment in the first year = 12 × principal part of monthly payment= 12 × (PMT - Interest) = 12 × (576.63 - 109.65)= $5,355.60

The balance outstanding at the end of the first year = PV × (1 + i)^(n÷12) - [PMT × ((1 + i)^(n÷12) - 1) ÷ i]

= 26315 × (1 + 0.0041666666666667)^(12) - [576.63 × ((1 + 0.0041666666666667)^(12) - 1) ÷ 0.0041666666666667]

= $20,509.15

For the fourth year, last 12 payments are made. In the fourth year, the loan balance outstanding is equal to the balance at the end of year 3.

Principal repayment in the fourth year = 12 × principal part of monthly payment= 12 × (PMT - Interest) = 12 × (576.63 - 47.10)= $6,719.16

Answer:

The fraction of the factor of 17.5 which is due to differences in capital per person is approximately 4.375, and the fraction due to differences in TFP is approximately 13.125.

Step-by-step explanation:

Based on the given information, we know that one-fourth (1/4) of the differences in per capita GDP across countries are due to differences in capital per person, and three-fourths (3/4) are due to differences in TFP.

Now, let's calculate the fractions for the United States and Kenya, given that the United States is 17.5 times richer than Kenya.

Let's represent the fraction due to differences in capital per person as "f_capital" and the fraction due to differences in TFP as "f_TFP".

Given:

f_capital = 1/4

f_TFP = 3/4

The factor of difference in wealth = 17.5

We need to determine the fractions of this factor of 17.5 that are due to each component.

The fraction due to differences in capital per person (f_capital) can be calculated as:

f_capital = (1/4) / (1/4 + 3/4)

f_capital = (1/4) / (4/4)

f_capital = 1/4

The fraction due to differences in TFP (f_TFP) can be calculated as:

f_TFP = (3/4) / (1/4 + 3/4)

f_TFP = (3/4) / (4/4)

f_TFP = 3/4

Now, to determine the fraction of the factor of 17.5 that is due to each component, we multiply each fraction by the factor:

Fraction due to differences in capital per person = f_capital * factor

= (1/4) * 17.5

= 4.375

Fraction due to differences in TFP = f_TFP * factor

= (3/4) * 17.5

= 13.125

Therefore, the fraction of the factor of 17.5 that is due to differences in capital per person is approximately 4.375, and the fraction due to differences in TFP is approximately 13.125.

Step-by-step explanation:

I apologize, I am unable to create tables or upload scanned documents. However, I can assist you in calculating the amount each investor will receive in each year based on the given information.

To calculate the amount received by each investor in each year, we need to follow these steps:

Calculate the total profit earned by the bank in each year by subtracting the loss values from zero.

Year 1: 0 - (-78,000) = 78,000

Year 2: 0 - (-23,000) = 23,000

Year 3: 29,000

Year 4: 63,000

Year 5: 103,500

Calculate the total profit to be distributed among the investors in each year, which is 60% of the total profit earned by the bank.

Year 1: 0.6 * 78,000 = 46,800

Year 2: 0.6 * 23,000 = 13,800

Year 3: 0.6 * 29,000 = 17,400

Year 4: 0.6 * 63,000 = 37,800

Year 5: 0.6 * 103,500 = 62,100

Calculate the profit share for each investor based on their respective share of the investment.

Year 1:

Fahad: (30/100) * 46,800

Yashara: (50/100) * 46,800

Saud: (20/100) * 46,800

Fariha: (40/100) * 46,800

Younus: (25/100) * 46,800

Asif: (35/100) * 46,800

Similarly, calculate the profit share for each investor in the remaining years using the same formula.

By following the calculations above, you can determine the amount each investor will receive in each year based on their share of the investment.

the area of the dartboard is approximately 254.34 square inches.

The area of a dartboard can be calculated using the formula for the area of a circle, which is given by:

Area = π * \(radius^2\)

Given that the radius of the dartboard is 9 inches, we can substitute this value into the formula:

Area = π * \(9^2\)

Area = π * 81

To calculate the area, we need to use the value of π (pi). Pi is an irrational number and is commonly approximated as 3.14. Using this approximation, we can calculate the area:

Area ≈ 3.14 * 81

The correct option is option b) subjectively divide the 20 plots into 10 pairs (making the plots within a pair as similar as possible) and then, for each pair, flip a coin to assign the fertilizers to the 2 plots.

A sort of probability called subjective probability is one that is based on a person's subjective assessment or personal knowledge of the likelihood of a particular result. It doesn't use facts or formal computations; instead, it merely includes the subject's ideas and prior experience.

A subjective likelihood varies from person to person and is not based on previous facts or market data. In other words, it is not founded on reality but rather is the result of an individual's opinion.

In the majority of probability theories, quantifiable data is evaluated to ascertain the likelihood of an event occurring. However, subjective probability lacks a formal calculation, is influenced by human ideas, and is not based on quantitative data.

Therefore, The correct option is option b) subjectively divide the 20 plots into 10 pairs (making the plots within a pair as similar as possible) and then, for each pair, flip a coin to assign the fertilizers to the 2 plots.

The most relevant answer to this question is researcher conducting a qualitative study knows that saturation of information has occurred when data collected confirms theoretical models.

In qualitative research, data saturation refers to when the collection of new data no longer leads to additional ideas or themes.

In other words, saturation occurs when data has been thoroughly explored and little or no new information or new patterns emerge.

so, the researcher can be sure that he or she has collected enough data to answer the research question, and collecting more data is unlikely for new insights.

Therefore, Using the data provided, we can calculate:  

x = (38.1 + 38.4 + 38.3 + 38.2 + 38.2 + 37.9 + 38.7 + 38.6 + 38.0 + 38.2) / 10 = 38.25

In a t distribution table or calculator, find the t value with 9 (n-1) degrees of freedom and 95% confidence intervals. This is approximately 2.262.

Substituting these values ​​into the formula gives:

therefore, the most relevant answer to this is data collected confirms theoretical models.

This means that the researcher has collected enough data to confirm or disprove their original theoretical models, and collecting more data is unlikely to change those models.
