From (0, 0), the points A and D in the graph are at (-1, -1) and (2, -1) respectively.

Since the scale factor is 2, every point will be moved twice a distance in both directions. (x and y).

So, multiplying both coordinates by 2, we will get the dilated points.

Hence, A' will be at (2 × (-1), 2 × (-1)) = (-2, -2) and D' will be at (2 × 2, 2 × (-1)) = (4, -2).

The quadratic model and the linear model of the table of values are the same

To do this, we make use of a graphing calculator.

From the graphing calculator, we have the following summary:

The regression equation is

y = mx + b

Where

m = SP/SSX = 28/10 = 2.8

b = MY - bMX = 22.6 - (2.8*0) = 22.6

So, we have:

y = 2.8x + 22.6

The sample size needed to provide a margin of error of 2 or less with a .95 probability when the population standard deviation equals 11 is 116.

Given margin of error of 2,probability of 0.95 and standard deviation is 11.

We have to calculate the sample size needed to provide a margin of error of 2 or less with a 0.95 probability when the population standard deviation of 11.

We know that the margin of error is the difference between the calculated values and actual values.

Margin of error=z*σ/[tex]\sqrt{n}[/tex]

where z is z value ,σ is standard deviation ,n is the sample size.

First we have to calculate the z value for the corresponding p value which is given of  0.95. We assume that the test is two tailed. z value is 1.96.

Now put the value of z , σ, n and margin of error in the formula of margin of error to get the value of n which is sample size.

2>=1.96*11/[tex]\sqrt{n}[/tex]

[tex]\sqrt{n}[/tex]>=(1.96*11)/2

[tex]\sqrt{n}[/tex]>=10.78

By squaring both sides we get,

n>=116.2064

Hence the sample size which is needed to provide a margin of error of 2 or less with a 0.95 probability when the population standard deviation equals 116.

  (4 -x)/(3 -9) = -8/5 . . . . substituting (9, x) for (x1, y1) and (3, 4) for (x2, y2)

Multiplying by 30, we have ...

  5(x-4) = -48

  5x -20 = -48 . . . . eliminate parentheses

Additional comment

In the attachment, we have written the point-slope equation of the line, then found the point on that line that has a x-coordinate of 9. We see the y-coordinate of that point is -5.6, as computed above.

If you swap the points (x1, y1) and (x2, y2), then the slope equation ends up with fewer minus signs to handle.

Step-by-step explanation:

The measures of the remaining side lengths of the triangle, AC and BC is 72 units and 31 units respectively.

B = 180 - (25 + 55)

B = 100⁰

sin (B)/AC = sin (C)/AB

sin (100)/AC = sin (55)/60

sin (100)/AC = 0.01365

AC = sin (100) / (0.01365)

AC = 72 units

sin (A)/BC = sin (C)/AB

sin (25)/BC = sin (55)/60

sin (25)/BC = 0.01365

BC = sin (25) / (0.01365)

BC = 31 units

Thus, the measures of the remaining side lengths of the triangle, AC and BC is 72 units and 31 units respectively.
