Write the equation of the circle with the given information.
Center: (-8, 0)
Diameter: 5

Answers

Answer:

(x + 8)² + y² = 6.25

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k ) = (- 8, 0 ) and r = 5 ÷ 2 = 2.5 , then

(x - (- 8))² + (y - 0)² = 2.5² , that is

(x + 8)² + y² = 6.25

Answers

Answer:

(a) [tex]b_1 =3.4[/tex] and [tex]b_0 = 83.7[/tex]

(b) [tex]y=83.7+3.4 x[/tex]

(c) [tex]r^2 = 0.790[/tex]

(d) [tex]\% Variation = 79.0\%[/tex]

(e) The expected earnings is: $110,900

Step-by-step explanation:

The data for the 10 sales person is as follows:

[tex]\begin{array}{ccc}{Years\ of Experience} & {Annual\ Sales(\$ 1000)} & {Salesperson} & {1} & {1} & {85} & {2} & {3} & {97} & {3} & {3} & {95}& {4} & {5} & {97}& {5} & {7} & {105}& {6} & {8} & {106}& {7} & {10} & {122} & {8} & {10} & {120} & {9} & {12} & {113} & {10} & {12} & {134}\ \end{array}[/tex]

Perform a regression analysis using Microsoft Excel

Note

I added two attachments to this solutionIn the first attachment, I highlighted the step to follow to perform regression analysis. At step 4, ensure that you fill in the input y range and the input x range. The input y range (in this question) is the column for sales person while the input x range is the annual sales Click ok, then Microsoft Excel will perform the analysis for you.

The question will be answered based on the result of the analysis performed by the application (See attachment 2)

See attachment 2 for the result of the analysis (I've highlighted the solution to each question on the attached file)

(a) b1 and b0

[tex]b_1 = 3.372767857[/tex]

[tex]b_1 \approx 3.4[/tex]

[tex]b_0 = 83.65625[/tex]

[tex]b_0 \approx 83.7[/tex]

(b) The estimated regression equation

The equation is of the form:

[tex]y =b_0 + b_1x[/tex]

Where:

[tex]b_1 =3.4[/tex]

[tex]b_0 =83.7[/tex]

So:

[tex]y=83.7+3.4 x[/tex]

(c) The coefficient of determination (r^2)

[tex]r^2 = 0.790361699[/tex]

[tex]r^2 \approx 0.790[/tex]

(d) Percentage of variation

To do this, we simply convert r^2 to percentage

[tex]\% Variation = r^2 * 100\%[/tex]

[tex]\% Variation = 0.790 * 100\%[/tex]

[tex]\% Variation = 79.0\%[/tex]

(e) Expected annual sales of a sales person with 8 years of experience.

Using the regression equation

[tex]y=83.7+3.4 x[/tex]

Where

[tex]x = 8[/tex] --- the years of experience.

So;

[tex]y = 83.7 + 3.4 * 8[/tex]

[tex]y = 83.7 + 27.2[/tex]

[tex]y = 110.9[/tex]

The expected earnings is: $110,900

Solve the equation 40 = -10(y+0.3). what does the y equal​

Answers

Answer:

y = -4.3

Step-by-step explanation:

40 = -10(y + 0.3) {Step 1: Use the distributive property to multiply -10 by y + 0.3}

40 = -10y + -10(0.3)

40 = -10y - 3 {Step 2: Add 3 to both sides.}

40 + 3 = -10y

43 = -10y {Step 3: Divide both sides by -10}

43/-10 = y

-4.3 = y

y equals -4.3.

Answer:

y = -4.3

Step-by-step explanation:

40 = -10(y + 0.3)

40 = -10y - 3

-3. -3

43 = -10y

Divide 43 by -10

y equal 4.3

To estimate the benefits of an SAT prep course, a random sample of 10 students enrolled in the course is selected. For each of these students, their entrance score on the exam taken at the beginning of the course is recorded. Their exit score on the exam they take at the end of the course is recorded as well. The table displays the scores.

A 3-column table with 10 rows. Column 1 is labeled student with entries 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. Column 2 is labeled Before with entries 800, 870, 860, 820, 1140, 1050, 850, 910, 830, 1140. Column 3 is labeled after with entries 1100, 1010, 1000, 980, 1410, 1270, 1020, 1010, 1060, 1340.

A 98% confidence interval for the mean difference (after – before) in score is 137.04 points to 248.96 points. Based on the confidence interval, is it reasonable to claim that the SAT prep course is beneficial?

Step-by-step explanation:

A 98% confidence interval for the mean difference (after – before) in score is 137.04 points to 248.96 points.

Based on the confidence interval if we go though the table we will find that each student show increase in confidence level .

As, At least the confidence level improved because it contains positive values only if we subtract previous value with the new values.

Therefore ,Yes, the confidence interval only contains positive values.
