The range of her scores is 17.
<em><u>Explanation</u></em>
Mindy's scores in five tests are:
First, rearranging the data in numerical order, we will get ........
<u>'Range' is the difference between the highest and lowest values</u>.
In the above data set, highest value is 95 and lowest value is 78
So, the range of her scores will be:
MO = 12 and PR = 3
Solution:
Given .
Perimeter of ΔMNO = 48
Perimeter of ΔPQR = 12
MO = 12x and PR = x + 2
<em>If two triangles are similar, then the ratio of corresponding sides is equal to the ratio of perimeter of the triangles.</em>
Do cross multiplication.
Subtract 48x from both sides.
Divide by 96 on both sides, we get
⇒ 1 = x
⇒ x = 1
Substitute x = 1 in MO an PR.
MO = 12(1) = 12
PR = 1 + 2 = 3
Therefore MO = 12 and PR = 3.
