Answer 1

The equation for the residual plot for the best fit line for the given data is y = 0.4940x + 34.4323 (rounded to 4 decimal places).

To fit a straight line to the given data points (x, y), we can use a method called linear regression. Linear regression finds the best-fitting line that minimizes the vertical distance between the line and the data points.

Let's calculate the slope and y-intercept of the line using the given data

Step 1: Calculate the means of x and y.

mean(x) = (71 + 68 + 73 + 69 + 67 + 65 + 66 + 67) / 8 = 68.25

mean(y) = (69 + 72 + 70 + 68 + 67 + 68 + 64) / 7 = 68.4286 (rounded to 4 decimal places)

Step 2: Calculate the differences from the means.

differences(x) = [71 - 68.25, 68 - 68.25, 73 - 68.25, 69 - 68.25, 67 - 68.25, 65 - 68.25, 66 - 68.25, 67 - 68.25]

differences(y) = [69 - 68.4286, 72 - 68.4286, 70 - 68.4286, 68 - 68.4286, 67 - 68.4286, 68 - 68.4286, 64 - 68.4286]

Step 3: Calculate the sum of the products of the differences.

sum_diff(xy) = sum(differences(x) [i] × differences(y)[i] for i in range(len(differences(x))))

Step 4: Calculate the sum of the squared differences of x.

sum_diff(x)_squared = sum((x - mean(x)) × 2 for x in [71, 68, 73, 69, 67, 65, 66, 67])

Step 5: Calculate the slope.

slope = sum_diff(xy) / sum_diff(x)_squared

Step 6: Calculate the y-intercept.

y = mean(y) - (slope × mean(x))

Now we can substitute the values we calculated into the equation y = mx + b, where m is the slope and b is the y-intercept.

The fitted line for the given data is

y = 0.4940x + 34.4323 (rounded to 4 decimal places)

Christie has $3.80 in quarters and dimes. She has three more dimes than quarters. How many of each coin does she have?

Answers

Answer:

Quarters = 10

Dimes = 13

Step-by-step explanation:

Given that :

Quarters = $0.25

Dimes = $0.10

Total value =. $3.80

Let :

Quarters = a

Dimes = a + 3 (3 more dimes Than quarters)

0.25a + 0.10(a + 3) = 3.80

0.25a + 0.10a + 0.3 = 3.80

0.35a = 3.80 - 0.3

0.35a = 3.5

a = 3.5 / 0.35

a = 10

Quarters = a = 10

Dimes = a + 3 = 10 + 3 = 13

Step-by-step explanation:

180 is a straight line.

x is among that line so you must subtract the angles you know from 180.

180-54-38= 16

Why does the sin 0 = cos (90 - 0)?

Answers

Answer:

It is a nonexistent circumstance where one point of a correct triangle gets zero. Attempt to think. At the point when the point becomes zero, at that point the base gets 0, and the opposite and the hypotenuse turns into a similar line. Since in cos 90, base is 0, in this manner consequently cos 90 is zero.

Draw the image of the following segment after a dilation centered at the origin with a scale factor of 2/3

Answers

Answer:

When we have a point (a, b) and we have a dilation of scale factor K centered at the origin, the new coordinates of this point will be:

(K*a, K*b)

In this case, we can find the original coordinates of the endpoints of the original segment.

Then apply the dilation to these points, and then draw a new segment whose endpoints are the dilated points.

The endpoints of the original segment are (i can not see the image very well, so i may be wrong when noticing the points).

The first endpoint is (6, 9) and (12, 12)

Now we apply a dilation with a scale factor K = 2/3.

then we get the points:

((2/3)*6, (2/3)*9) = (4, 6)

and the other point is:

((2/3)*12, (2/3)*12) = (8, 8)

Now we need to draw a segment whose endpoints are (4, 6) and (8, 8)

The segment can be seen in the graph below.

URGENT: Create a linear system whose ONLY SOLUTION is (3,13) . I just need the equations for f(x)=? , G(x)=? To get (3,13). ASAP!!!!! PLZZZ

Answers

The solution of (3,13) means you need to create two lines that satisfy x = 3 and y = 13

The two lines can be anything as long as they give this solution

For example, if you wrote x + y = 16 (you know their values already)

Then write another y - x = 10

From here you have your equations, turn them into the f(x) form.

x + y = 16 can be turned into y = 16 - x which is f(x)=16-x

y-x = 10 can be turned into y = 10 + x which is g(x)=10 + x

Write an equation of a line perpendicular to x = -7 and passes through the
point (4,9).

Answers

Answer:

y = 9

Step-by-step explanation:

The line x = -7 is a vertical line, so the perpendicular line will be horizontal.

Horizontal lines have a slope of 0.

Using this slope and the point given, plug them into y = mx + b to solve for b and create the equation

y = mx + b

9 = 0(4) + b

9 = b

Plug this and the slope into the equation:

y = mx + b

y = 0x + b

y = 9

So, y = 9 is the equation

Solve for x.
