Answer:

\(\huge\boxed{y=4x-7}\)

Step-by-step explanation:

Linear equations will always be in the form \(y=mx+b\), where m is the slope and b is the y-intercept

Since we know nothing about this equation, other than the fact that there are two points in it, we must find the slope and the y-intercept.

Luckily, we have two points to work with. We know that the slope between two points will be the change in y divided by the change in x (\(\frac{\Delta y}{\Delta x}\)), so we can use the two points given to us to find both changes.

The y value goes from 1 to 17, which is a \(17-1=16\) change.

The x value goes from 2 to 6, which is a \(6-2=4\) change.

Now that we know both changes, we can divide the change in y by the change in x.

\(\frac{16}{4}=4\)

Now that we know the slope (4), we can plug it into our equation (\(y=mx+b\)).

\(y=4x+b\)

Now all we need to do is find the y-intercept. Since we know the slope and one of the points the line passes through, we can find the y-intercept by substituting in the values of x and y. Let's use the point (2, 1).

Therefore our y-intercept is -7. Now that we know the slope and the y-intercept, we can plug it into our equation.

\(y=4x-7\)

Answer:

A) 2nd graph

Explanation:

The 1st graph shows a radical expression, where:

to find the inverse, replace f(x) with y, switch the x and the y, then solve for y. The only graph showing exponential growth is the 2nd graph (note how at 1 it's 1, at 2 it's 4, at 3 it will be 9, etc.)

The molar mass of

a) Ca: 0.1 mol, F: 0.2 mol

b) Na: 0.0 mol, O: 0.0 mol

c) K: 0.3 mol, Mn: 0.3 mol, O: 1.3 mol.

a) The molar mass of calcium (Ca) is approximately 40.1 g/mol, and the molar mass of fluorine (F) is approximately 19.0 g/mol.

To calculate the number of moles for each element:

- Moles of Ca = 3.65 g / 40.1 g/mol ≈ 0.091 mol

- Moles of F = 3.65 g / 19.0 g/mol ≈ 0.192 mol

Expressed using one decimal place and separated by a comma, the results are:

- Moles of Ca: 0.1

- Moles of F: 0.2

b) The molar mass of sodium (Na) is approximately 23.0 g/mol, and the molar mass of oxygen (O) is approximately 16.0 g/mol.

To calculate the number of moles for each element:

- Moles of Na = 0.340 g / 23.0 g/mol ≈ 0.015 mol

- Moles of O = 0.200 g / 16.0 g/mol ≈ 0.013 mol

Expressed using one decimal place and separated by a comma, the results are:

- Moles of Na: 0.0

- Moles of O: 0.0

c) The molar mass of potassium (K) is approximately 39.1 g/mol, the molar mass of manganese (Mn) is approximately 54.9 g/mol, and the molar mass of oxygen (O) is approximately 16.0 g/mol.

To calculate the number of moles for each element:

- Moles of K = 12.8 g / 39.1 g/mol ≈ 0.327 mol

- Moles of Mn = 17.2 g / 54.9 g/mol ≈ 0.313 mol

- Moles of O = 20.3 g / 16.0 g/mol ≈ 1.269 mol

Expressed using one decimal place and separated by commas, the results are:

- Moles of K: 0.3

- Moles of Mn: 0.3

- Moles of O: 1.3

Answer:

Part A

The worth of the stock in 7 years is approximately $145.68

Part B

The worth of the stock in 2016 is approximately $62.48

Part C

f(7) = 85 × (1 + 0.08)⁷

Part D

85 × (1 + 0.08)⁻⁴

Step-by-step explanation:

Question

"The value of the πPhone πhas increased 8% each year for the past several years. In 2020, the stock was worth $85. What will the stock be worth in 7 years? What was the stock worth in 2016? Equation: 7 years from now? in 2016?"

The equation for the growth of the stock to a final amount f(x) is given by the general equation for exponential growth as follows;

\(f(t) = a \cdot (1 + r)^t\)

Where, in relation to the stocks;

f(t) = The value of the stocks after 't' years

a = The initial amount of the stocks

r = The rate of growth of the stock = 8%

t = The number of years of growth

Part A

The worth of the stock in 7 years, f(7), is found as follows;

The (initial) value of the stock in 2020, a = $85

The rate of increase in the value of the stock = The growth rate of the stock, r = 8% = 8/100 = 0.08

The number of years of growth, t = 7 years

We get;

f(7) = 85 × (1 + 0.08)⁷ ≈ 145.68

The worth of the stock in 7 years, f(7) ≈ $145.68

Part B

The value of the stock in 2016 is found as follows;

The number of years between 2020 and 2016 = 2016 - 2020 = -4 (years)

Here, let 'f(t)' represent the value of the stock in 2016, and therefore, we have;

t = -4 years

r = 8% = 0.08

a = The value of the stock in 2020 = $85

Plugging in the values gives;

f(-4) = 85·(1 + 0.08)⁻⁴ = 85 × (1.08)⁻⁴ ≈ 62.48

The value of the stock in 2016, f(-4) ≈ $62.48.

Part C

The equation for 7 years from now is f(7) = 85 × (1 + 0.08)⁷

Part D

The equation for 2016 is f(-4) = 85 × (1 + 0.08)⁻⁴.

In an investigation on accuracy and precision, Myriah measures the mass of a 10. 00 g piece of metal several times. Her measurements are 9. 98 g, 10. 02 g, 10. 01 g, and 9. 99 g. The statement that best describes Myriah's results is that they are precise but not accurate.

Accuracy refers to how close a measured value is to the true or accepted value. Precision refers to the degree of agreement among repeated measurements. The mean of her measurements is: (9.98 g + 10.02 g + 10.01 g + 9.99 g) / 4 = 9.25 g. The results are precise because they are close together, and the mean value was calculated to the nearest hundredth of a gram. The measurements, on the other hand, were not accurate because they were all significantly less than the true value of 10.00 g.

To find the measure of angle A, place the protractor so that the base of the angle is aligned with the bottom line of the protractor. Then, read the measurement where the other side of the angle intersects the protractor. In this case, angle A intersects the protractor at 45 degrees. To find the measure of angle B, place the protractor so that the base of the angle is aligned with the bottom line of the protractor. Then, read the measurement where the other side of the angle intersects the protractor. In this case, angle B intersects the protractor at 120 degrees. Therefore, the measure of angle A is 45 degrees, while the measure of angle B is 120 degrees.

Let the bigger number be 'p' and the smaller number 'p'.

Since the numbers have a difference of 8, then  p - q = 8

& since the larger number is two more than twice the smaller, then

                                                                                                        p = 2q + 2

⇒   (2q + 2) - q = 8                       [by substituting for equation for p]

                     q = 6

Since q = 6,

⇒  p - 6 = 8

          p = 14

∴ the smaller number is 6 and the bigger 14

Answer:

Pablo has eaten 2 1/2 chocolate bars.

Step-by-step explanation:

We know that:

- Each bar was divided into 8 equal pieces

- Pablo ate 20 pieces

So, we can find the chocolate bars that he has eaten as follows:

\( f = \frac{1 \: bar}{8 \: pieces}*20 \: pieces = 2.5 \: bars = 2\frac{1}{2} \: bars \)    

Hence, Pablo has eaten two and a half of chocolate bars expressed as 2 1/2 as a mixed fraction.

We know that 4 oz of steak contains 700 mg of potassium. We want to know how many mg of potassium a 10 oz steak has. The bigger the steak the more potassium it has, so it is a directly proportional relationship. We can apply a rule of three to find the value we want as shown below:

Since hte relationship is proportional we don't need to invert any of the fractions. The first step is to cross multiply and then solve for x.

A 10 oz steak contains 1750 mg of potassium. We want to know how many percent of the daily value we consumed by eating that steak. To do that we can create another rule of three as shown below:

We ate 50 % of the daily value of potassium recommended.

A sample size of 1076 is needed , To calculate the required sample size for estimating a population proportion with a desired margin of error and confidence level, we can use the formula:

n = (\(Z^2\) * p * (1-p)) / \(E^2\)

where:

- n is the required sample size

- Z is the z-score corresponding to the desired confidence level

- p is the estimated population proportion

- E is the desired margin of error

Let's calculate the required sample size for each exercise:

6.15: Margin of error within 25% with 95% confidence.

E = 0.25

Z = 1.96 (corresponding to 95% confidence level)

p is not given, so we can assume a worst-case scenario where p = 0.5 (maximum variability).

Substituting these values into the formula:

n = (1.96^2 * 0.5 * (1-0.5)) / 0.25^2

n ≈ 384.16

Rounding up to the nearest whole number:

n = 385

Therefore, a sample size of 385 is needed.

6.16: Margin of error within +1% with 99% confidence.

E = 0.01

Z = 2.58 (corresponding to 99% confidence level)

p is not given, so we can assume a worst-case scenario where p = 0.5 (maximum variability).

Substituting these values into the formula:

n = (2.58^2 * 0.5 * (1-0.5)) / 0.01^2

n ≈ 6658.08

Rounding up to the nearest whole number:

n = 6659

Therefore, a sample size of 6659 is needed.

6.17: Margin of error within +3% with 90% confidence.

E = 0.03

Z = 1.645 (corresponding to 90% confidence level)

p = 0.3 (estimated population proportion)

Substituting these values into the formula:

n = (1.645^2 * 0.3 * (1-0.3)) / 0.03^2

n ≈ 317.91

Rounding up to the nearest whole number:

n = 318

Therefore, a sample size of 318 is needed.

6.18: Margin of error within +2% with 95% confidence.

E = 0.02

Z = 1.96 (corresponding to 95% confidence level)

p = 0.78 (estimated population proportion)

Substituting these values into the formula:

n = (1.96^2 * 0.78 * (1-0.78)) / 0.02^2

n ≈ 1075.56

Rounding up to the nearest whole number:

n = 1076

When testing the null hypothesis with an alpha value of 0.05, the critical value will be larger than if you were testing with an alpha value of 0.01.

If you are testing the null hypothesis with an alpha value of 0.05, the critical value will be smaller than if you were testing the alpha value of 0.01. This is because a smaller alpha value means a more stringent test of significance, which requires stronger evidence to reject the null hypothesis.

Therefore, the critical value is larger for a smaller alpha value to reflect the higher level of evidence required for rejection. Conversely, a larger alpha value allows for a less stringent test of significance, requiring weaker evidence to reject the null hypothesis, which results in a smaller critical value.

To calculate cumulative cash surplus/ deficit we need to consider cash flows during quarter, including sales, purchases, accounts receivable, accounts payable, cash expenses, taxes,  initial cash,loan balances.

Calculate the total cash inflows from sales for Q1: $46,000 (Q1 sales) * 71% (purchases as a percentage of next quarter's sales) = $32,660.

Calculate the total cash outflows for Q1: $1,500 (monthly cash expenses) * 3 months + $400 (monthly taxes) * 3 months = $5,700 + $1,200 = $6,900.

Calculate the net cash flow from accounts receivable: $32,660 (total cash inflows from sales) - $12,200 (accounts receivable balance at the beginning of Q1) = $20,460.

Calculate the net cash flow from accounts payable: $48,000 (Q2 sales projection) * 45 days / 30 days = $72,000 (purchases for Q2) - $14,800 (accounts payable balance at the beginning of Q1) = $57,200.

Calculate the net cash flow from short-term borrowing: Since the short-term loan balance is zero at the beginning of Q1 and there is no mention of additional borrowing, the net cash flow from short-term borrowing is zero.

Calculate the net cash flow for Q1: Net cash flow = Cash inflows - Cash outflows = $20,460 (net cash flow from accounts receivable) - $6,900 (total cash outflows) + $57,200 (net cash flow from accounts payable) = $70,760.

Calculate the cumulative cash surplus/deficit at the end of Q1: Cumulative cash surplus/deficit = Initial cash balance + Net cash flow - Minimum cash balance = $280 (initial cash balance) + $70,760 (net cash flow) - $250 (minimum cash balance) = $71,790.

Therefore, the cumulative cash surplus (deficit) at the end of Q1, prior to any short-term borrowing, is $71,790.
