Answer:
The probability is 3/10, or 30%.
Step-by-step explanation:
A probability P is the ratio of the number of favorable (relevant) cases and the total number of all possible cases.
The probability that Red and Small is selected can be estimated using values from the table:
P(Red and Small) = #(Red and Small) / # (total) = Value(2nd row, 2nd column) / Sum (all cells in the table) = 12/40 = 3/10 = 30%.
Answer:
A) x²/25 + y²/9 = 1
Step-by-step explanation:
The major axis length is the sum of distances to the foci from the ellipse, 10. So the semi-major axis has length 10/2 = 5. The foci are on the x-axis, so the ellipse is oriented horizontally.
The semi-minor axis is the other leg of the right triangle having the focus and center as one leg, and the semi-major axis as the hypotenuse. This is obviously a 3-4-5 triangle, so the semi-minor axis length is 3.
When the ellipse is horizontal, the formula for it is ...
... (x/(semi-major axis))² + (y/(semi-minor axis))² = 1
... (x/5)² + (y/3)² = 1
... x²/25 + y²/9 = 1
