Answer:

Scale factor = 1.5

Step-by-step explanation:

Formula for the scale factor,

Scale factor = \frac{\text{Measure of one side of the Image}}{\text{Measure of one side of the preimage}}

In this question, image is triangle Y and preimage is triangle X.

Scale factor of X to Y = \frac{15}{10}

                                    = 1.5

Therefore, scale factor = 1.5 is the answer.

Which of the following will make a confidence interval narrower and more precise?
swat32

Answer:

B. Larger sample size and lower confidence level

Step-by-step explanation:

The margin of error of a confidence interval is given by the following formula:

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

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

z is related to the confidence level. The higher the confidence level, the higher the value of Z.

So, the margin of error is direct proportion to the confidence level and inverse proportional to the sample size.

We want to decrease the margin of error.

So the correct answer is:

B. Larger sample size and lower confidence level

(4x + 2)(-2x - 3)

F: -8x²     O: -12x       I: -4x       L: -6

-8x² - 16x - 6

(2x + 1)(2x - 1)

F: 4x²     O: -2x       I: 2x       L: -1

4x² - 1
