Can you tell me da answer for both of the questions pls and u

Step-by-step explanation:

a) Range means the difference between the highest and lowest number in the given data. So as to make our calculations easier, we write the numbers in ascending order. After that we subtract the smallest number from the largest one.

b) range=17.5-12.3

=5.2

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
