4x^2+25y^2=100
Domain of an ellipse is x ∈ [-a,a] and Range of an ellipse is y ∈ [-b,b].
So, given equation is an Ellipse where Domain is x ∈ [-5,5] and Range is y ∈ [-2,2].
5 3/4 divided by 4 1/2 23/4 divided by 9/2 23/4 times 2/9 46/36 = 1 and 10/36 (reduced) = 1 and 5/18 inches
Answer:
80%
Step-by-step explanation:
Percentile rank = (number of scores lower or equal to 82 / total number of scores) * 100%
Percentile = (8 / 10) * 100%
= 0.8 * 100%
= 80%
The answer is 1/20 or 0.05
