What is the equation in standard form of an ellipse centered at the origin and vertex (1,0) and focus (4,0)

The correct question is
What is the equation in standard form of an ellipse centered at the origin and vertex (4,0) and focus (1,0)


we know that
Standard form of equation for an ellipse with horizontal major axis is
(x-h)²/a²+(y-k)²/b²=1
the center is the origin
so
(h,k) is (0,0)length of horizontal major axis> 8=2a> a=4
a²=16
c=1 (distance from center to focal point)
c²=1
b²=a²-c²> b²=16-1> b²=15

the equation is
(x)²/16+(y)²/15=1

the answer is
(x)²/16+(y)²/15=1

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

the answer is 18.
