A negative and a negative equal a positive.

It would be 16m + 5m - 4

You would keep the -4 the same since it isn't being multiplied by anything.

I hope this helps!

For the dilation, Do, k = (10, 0 ) —> (5,0) , the scale factor is equal to ____.
Vladimir [108]

Answer:

•0.5

Step-by-step explanation:

We'll assume the dilation was done at the origin point, so it was done evenly.

Since the k point went from (10,0) to (5,0), we know it was reduced... so the scale factor has to be below 1. A scale factor means the size wasn't changed and a dilation/scale factor larger than 1 means it was enlarged.

So, we take the new X-value (5) and divide it by the original X-value (10).

Scale factor = 5/10 = 1/2... so 0.5

Gwar [14]

Answer:

A sample size of 385 should be used.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1 - 0.95}{2} = 0.025

Now, we have to find z in the Ztable as such z has a pvalue of 1 - \alpha.

That is z with a pvalue of 1 - 0.025 = 0.975, so Z = 1.96.

Now, find the margin of error M as such

M = z\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

What sample size should be used (round the number up)

A sample of n should be used.

n is found when M = 5.

We have that \sigma = 50

M = z\frac{\sigma}{\sqrt{n}}

5 = 1.96\frac{50}{\sqrt{n}}

5\sqrt{n} = 1.96*50

Simplifying by 10

\sqrt{n} = 1.96*10

\sqrt{n} = 19.6

(\sqrt{n})^2 = (19.6)^2

n = 384.16

Rounding up

A sample size of 385 should be used.
