Assume that the initial coordinates are (x,y) and that the dilated coordinates are (x',y').

The dilation is therefore:

(x,y) ............> (x',y')

Now, let's assume that the dilation factor is k.

Therefore:

x' = kx

y' = ky

Based on the above, all the student has to do is get the initial coordinates and the final ones and then substitute in any of the above two equations to get the value of k.

Example:

Assume an original point at (2,4) is dilated to coordinates (4,8). Find the dilation factor.

Assume the dilation coefficient is k.

(x,y) are (2,4) and (x',y') are (4,8)

Therefore:

x' = kx .........> 4 = k*2 ..........> k = 2

or:

y' = ky ..........> 8 = k*4 .........> k = 2

Based on the above, the dilation coefficient would be 2.

Hope this helps :)

Need help on #6 step by step I'm so confused how this works I always get stuck
inna [77]
To find the variable x, set the two outside equations equal to each other because all sides are equal
x+13=3x+3
13=2x+3
10=2x
x=5

then to find h, you set the equation equal to 90 because that's how many degrees it is
2h-45=90
2h=135
h=67.5

A clinical trial was conducted to test the effectiveness of the drug zopiclone for treating insomnia in older subjects. Before t
aleksklad [387]

Answer:

We cannot say that the mean wake time are different before and after the treatment, with 98% certainty. So the zopiclone doesn't appear to be effective.

Step-by-step explanation:

The goal of this analysis is to determine if the mean wake time before the treatment is statistically significant. The question informed us the mean wake time before and after the treatment, the number of subjects and the standard deviation of the sample after treatment. So using the formula, we can calculate the confidence interval as following:

IC[\mu ; 98\%] = \overline{y} \pm t_{0.99,n-1}\sqrt{\frac{Var(y)}{n}}

Knowing that t_{0.99,15} = 2.602:

IC[\mu ; 98\%] = 98.9 \pm 2.602\frac{42.3}{4} \Rightarrow 98.9 \pm 27.516

IC[\mu ; 98\%] = [71.387 ; 126,416]

Note that 102.8 \in [71.384 ; 126.416] so we cannot say, with 98% confidence, that the mean wake time before treatment is different than the mean wake time after treatment. So the zopiclone doesn't appear to be effective.
