A chi-square goodness-of-fit test is to be conducted to test whether a population is normally distributed. no statement has been made regarding the value of the population mean and standard deviation. a frequency distribution has been formed based on a random sample of 500 values. the frequency distribution has equal 7 classes. assuming that the test is to be conducted at the alphaequals0.01 level, determine the correct decision rule to be used.

i think is g(1)=-1.

hope that i can

answer for #1 is c

answer for #2 is d

can i get brainliest

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.
