Answer:
There were 42 fewer students who chose Football than Hockey.
Step-by-step explanation:
Fraction of students who chose Hockey
= 1 - -
=
units = 21
1 unit = 42
No. of students who chose Football
= 2 units ()
= 84 students
No. of students who chose Hockey
= 3 units ()
= 126 students
Difference between no. of students who chose Football and Hockey
= 126 - 84
= 42 students
∴There were 42 fewer students who chose Football than Hockey.
Answer:
(- 2, 9 )
Step-by-step explanation:
Given a parabola in standard form, y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= -
y = - x² - 4x + 5 ← is in standard form
with a = - 1 and b = - 4, thus
= - = - 2
Substitute x = - 2 into equation for corresponding y- coordinate
y = - (- 2)² - 4(- 2) + 5 = - 4 + 8 + 5 = 9
vertex = (- 2, 9 )
The height will be 50.
To calculate area, you must know the base and height.
Since it’s already given to you, you must calculate it. Well... what times 1 gives me 50?
1x50=50
The answer is 90 people because total amount of people is 300
