Let a (1, 3, 5, 7}, b (5, 6, 7, 8}, c (5, 8} d {2, 5, 8}, and u 1, 2, 3, 4, 5, 6, 7, 8}. determine whether the statement shown below is true or false. if it is false, then give the reason. a#(7, 5, 3, 1 a. false; a has different elements than those listed. b. false; the elements in a are in a different order. c. false; the elements in a are the same as those listed d. true

True

Step-by-step explanation:

Given are some sets A, B, C, D and Universal set U.

We have

When we change the order of elements of A in any manner also the set A' thus obtained will be equal to A only

Hence here A' = =A

This is because whenever we take any element x in A this belongs to A'

Hence

Similarly any element y in A' also belongs to A

So A⊂A'

Together we have

Option d true

answer: howdy

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
