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.
In this problem WP means what percent
20 = WP X 160
solve for WP, by dividing both sides by 160
and you get:
0.125 = WP
Change your decimal into a percent by multiplying by 100%
12.5% is your result.
Subtracting whole numbers does not include subtracting negative numbers, whereas when subtracting integers you can include negative numbers.
Answer:
If AB is a tangent to the circle, the triangle ABO is right angled, as the angle where a tangent meets the circumference is always 90 degrees.
We also know that Pythogoras' theorem only holds for right angled triangles.
The hypotenuse is 12 + 8 as 12 is the radius so is 20.
16^2+12^2 = 256 + 144 = 400 = 20^2 so AB must be tangent.
3x
We need to substitute x with 5 because the question is asking how many squats Carlos has completed if he completed 5.
3 x 5 = 15
Therefore, Carlos completed 15 squats as part of his football workout.
By the way, this question is very simple and basic. I recommend reviewing Algebra for your benefit/
