Answer:
13 3/4 cupcakes for each person
Step-by-step explanation:
55 cupcakes and 4 friends
55/4 = 13 3/4
First, we need to transform the equation into its standard form (x - h)²=4p(y - k).
Using completing the square method:
y = -14x² - 2x - 2
y = -14(x² + 2x/14) - 2
y = -14(x² + 2x/14 + (2/28)²) -2 + (2/28)²
y = -14(x + 1/14)² - 391/196
-1/14(y + 391/196) = (x + 1/14)²
This is a vertical parabola and its focus <span>(h, k + p) is (-1/14, -391/196 + 1/56) = (-1/14, -775/392).
Or (-0.071,-1.977).</span>

50 in, 48 in, 14 in are the side lengths that form a right triangle
Answer:
1/2
Step-by-step explanation:
There are a total of 25 students. 3 don't study art or biology. 10 study only biology. 6 study both art and biology. This means the remaining students only study art.
1. Calculate the number of students taking art
only art: 25 - 3 - 6 - 10 = 6
number of students taking art and biology: 6
total number of students taking art: 12
2. Calculate the probability
Out of the 12 total students taking art, 6 are in art and biology.
6/12 = 1/2
