Arguably, all of them are at least somewhat biased, but the most biased would be <span>surveying people 15 to 20 years old leaving a concert </span> because being at a concert would be highly correlated with liking the type of music played at that concert.
I belive the answer to be b
Step-by-step explanation:
It is an isosceles triangle , it has two equal angles both 55°.
All Isosceles triangles have two equal angles <em>a</em><em>n</em><em>d</em> two equal sides.
So in this case x +18 is equal to 3x, and to find x you will equal them to each other to create a linear equation and solve.
x + 18 = 3x
x - 3x = -18
-2x = -18
× = -18 / -2
× = 9 <em>(</em><em>a</em><em>n</em><em>s</em><em>)</em><em> </em>
Hope I was able to help. Good Luck :)))
$530.40/4= $132.60
$132.60 x 3=$397.80
Or
$530.40 x .75= $397.80
we are given

Firstly, we will find all possible factors of 144

we can also write as

now, we can put exponent to over entire term

now, we can replace 144

now, sqrt will get cancelled with square
and we get

now, we can simplify it
