Answer:

10miles I think

Step-by-step explanation:

The required distance between, Nate's house and the restaurant is 7.5 miles.

From the graph,

Consider point C on the graph, which is 6  and 8 units apart from A and B respectively.

The distance between, Nate's house and the restaurant is given as,
AB = √[AC² + BC²]
AB = √[6² + 8²]
AB = 10 units

Now 1 unit = 3/4 miles
AB = 10 * 3/4
AB = 7.5 miles

Thus, the required distance between, Nate's house and the restaurant is 7.5 miles.

The regression equation is:

y = 20.85 + 0.735 * x

Year Motor registration (000 nos.) No. of tyres sold (000 nos.)

2 62 65

3 65 70

4 48 53

5 53 73

6 60 68

7 68 60

8 60 8

9 9 10

10 65 82

11 72 62

12 62 80

13 40 52

(a) In order to ascertain the coefficient of correlation between the registration of the motor and the number of tires sold, we can apply the following formula:

r = Σ[(xi - x_mean)(yi - y_mean)] / √[Σ(xi - x_mean)^2 * Σ(yi - y_mean)^2].

To do this, we need to determine the mean values for the motor registration (x) and the number of tyres purchased (y).

[tex]x_m_e_a_n = (62 + 65 + 48 + 53 + 60 + 68 + 60 + 9 + 65 + 72 + 62 + 40) / 12 = 664 / 12 = 55.33\\y_m_e_a_n = (65 + 70 + 53 + 73 + 68 + 60 + 8 + 10 + 82 + 62 + 80 + 52) / 12 = 733 / 12 = 61.08[/tex]

Now, we can calculate the required sums for the correlation formula:

Σ(xi - x_mean) = -39

Σ(yi - y_mean) = -39

Σ(xi - x_mean)^2 =3543

Σ(yi - y_mean)^2 = 6649

Σ[(xi - x_mean)(yi - y_mean)] = 2604

Now, we can calculate the correlation coefficient:

r = 2604 / √(3543 * 6649) ≈ 0.556

(b) Interpret your result:

With a correlation coefficient, r, between -1 and 1 going up to 0.556, it shows up as a significant positive relationship.

So when the number of car registrations augments, the sales of tires will also go up.

(c) Test the significance of the result:

As the t-statistic is listed as 1.934, we can analyze it using the critical t-value from a t-distribution table which is around 2.228.

Consequently, since the t-statistic (1.934) is lower than the critical t-value (2.228), the correlation between them is not statistically significant at the 0.05 level.

(d) Compute the two regression coefficients:

The two regression coefficients can be calculated using the following formulas:

b1 = Σ[(xi - x_mean)(yi - y_mean)] / Σ(xi - x_mean)^2

b0 = y_mean - b1 * x_mean

Using the previously calculated values:

b1 = 2604 / 3543 ≈ 0.735

b0 = 61.08 - 0.735 * 55.33 ≈ 20.85

The regression equation is:

y = 20.85 + 0.735 * x

(e) Estimate the number of tyres to be sold when the expected motor registration is 92,000:

Using the regression equation, we can predict the number of tyres to be sold when the expected motor registration is 92,000 (92 in thousands):

y = 20.85 + 0.735 * 92 ≈ 87.81

We estimate that when the expected motor registration is 92,000, approximately 87,810 tyres will be sold.

It should be stated that the relationship was not considered to be statistically relevant so care is advised.

Step-by-step explanation:

Notice how we have 3 relative extrema , this means our equation has a degree of 4.

Notice how at root 1, our graph bounces off the curve.

This means we have a multiplicity of 2 there so one of our roots are

[tex](x - 1) {}^{2} [/tex]

For roots -3, and 4, our graph just passes through the x axis so those are roots with a multiplicity of 1.

[tex](x + 3)[/tex]

So our equation is

[tex]y = (x - 1) {}^{2} (x + 3 )(x - 4)[/tex]

The graph passes through(-1,-2) so let see if we need any constant

$48.07 would be the monthly payments on the loan.

We must first determine the total amount of interest charged over the course of the 4-year term in order to determine the monthly payments on a basic interest add-on loan.

The formula for simple interest is:

I = P * r * t

where I is the interest charged, P is the principal (the amount borrowed), r is the annual interest rate as a decimal, and t is the time period in years.

In this case, P = $1,426.25, r = 0.1545 (15.45% expressed as a decimal), and t = 4 years. So, the total amount of interest charged is:

I = $1,426.25 * 0.1545 * 4

I = $881.25

Adding the interest to the principal, we get the total amount paid over the 4-year term:

Total amount = $1,426.25 + $881.25

Total amount = $2,307.50

We must divide the sum by the number of months left in the loan term in order to get the monthly installments. As the loan period is 4 years long, there are 48 months:

Monthly payment = Total amount / Number of months

Monthly payment = $2,307.50 / 48

Monthly payment = $48.07

Therefore, the monthly payments on the loan would be $48.07.

According to the information, the interest earned on the annuity over the 20-year period is $78,066.89.

To find the value of the annuity, we can use the formula:

where:

In this case, PMT = $7,000, r = 6.5% per year compounded annually, and n = 20 years.

First, we need to convert the annual interest rate to a periodic interest rate. Since the interest is compounded annually, the periodic interest rate is the annual rate divided by the number of periods in a year:

i = r / m

where,
m = number of compounding periods per year.

In this case, since the interest is compounded annually, m = 1, so:

i = 6.5% / 1 = 0.065

Now we can plug in the values and solve for V:

V = $7,000 x [(1 + 0.065)^20 - 1] / 0.065

V = $218,066.89

Therefore, the value of the annuity is: $218,066.89.

To find the interest earned on the annuity over the 20-year period, we can subtract the total amount deposited from the total value of the annuity:

There are numerous concepts in algebra 2 that can be applied in real life scenarios. Some of which are linear equations and quadratic functions. The linear equation, for instance, helps to estimate that the cost i.e. of gas for a trip.

Linear equations can be used in real-life for calculating distances, rates and costs. For instance, during plan for a road trip, it can be used to estimate distance, time it takes to travel, estimated cost of gas etc.

An illustration is when one is planning a road trip from New York to Los Angeles. We can estimate that the distance between the two cities is 2,800 miles and car has average fuel efficiency of 25 miles per gallon.

If gas costs $3.50 per gallon, We can use the linear equation to get the cost of trip which is:

= Distance / Miles per gallon * Price per gallon

= 2,800 / 25 * 3.50

We can use the transformations of the graph of y=1/x to graph the rational function r(x) = 2x-9/x-4.

First, we will shift the graph of y=1/x to the right by 4 units to get the graph of y=1/(x-4). Next, we will stretch the graph vertically by a factor of 2 to get the graph of y=2/(x-4). Finally, we will shift the graph down by 9 units to get the graph of r(x) = 2x-9/x-4.

The domain of r(x) is all real numbers except x=4, since that would make the denominator zero. The range of r(x) is also all real numbers except y=2, since that would make the numerator zero.

This equation is based on the information that the 45 expensive wood costs $3.00 more than the 60 cheap wood. In other words, if the price of the 60 cheap wood is x, the price of the 45 expensive wood is x + 3.

Since,  Algebra involves working with numbers, equations, and variables to solve real-world problems and understand abstract relationships.

Now, To solve this equation, we must use algebra and solve for x.

First, we multiply both sides of the equation by 4/5. This gives us:

48x + 36 = 45x

-36 = 3x

Finally, we divide left side of the equation by 3, giving us the final solution:

x = -12

Therefore, the price of the 60 cheap wood is $12, and the price of the 45 expensive wood is $15.
