In a survey, adults and children were asked whether they prefer hamburgers
or pizza. the survey data are shown in the relative frequency table.
about 60% of adults prefer pizza.
compare this with the percentage of children who prefer pizza.

select the true statement.
d
a. a greater percentage of children (64%) prefer pizza.
o
b. a smaller percentage of children (43%) prefer pizza.
c. a smaller percentage of children (30%) prefer pizza.
d. a greater percentage of children (about 70%) prefer pizza.

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.

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
