A researcher creates two random samples, each with a sample size of 10. He
does not find a statistically significant difference between the two groups.
Which of the following statements is correct? Select all that apply.
O
A. Since the sample size is not adequate, the conclusion is likely to
be untrue.
B. Sample size does not affect the outcome of statistical
significance.
C. Since the sample size is adequate, the conclusion is likely to be
true.
D. Since random samples were used, the conclusion is likely to be
true

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7

step-by-step explanation:

because i took test

-1/4 > -1 2/3. -1/4 is greater than -1 2/3 because it is closer to 0 on the number line.
