Answer:
f(- 3) = 18
Step-by-step explanation:
Substitute x = - 3 into f(x) , that is
f(- 3) = 2(- 3)² = 2(9) = 18
Answer:
x = -2
Step-by-step explanation:
First, add 1/3 to both sides. You end up with 5/6x = -5/3. Next, you divide both sides by 5/6. You should finish with x = -2.
Answer:
a.) First check on the height of the bar that ranges between 20 and 24 which is 6. The 6 is the number of students who bought 20 books or more, so get the percentage of those students who bought 20 or more books; divide 6 which is the number of students who bought 20 books or more with the total number of students which is 40 then multiply with 100.
% of students who bought 20 or more books = 6/40 ×100
=15
Step-by-step explanation:
b.) Find the area of a trapezium
= 1/2 × {a+b} × h
= 1/2 × {9 + 13} ×12
= 132
= 1/2 × {13 + 6} × 12
= 108
Mean no. of books bought = 132 + 108
= 240
