Answer:
Not teenagers = 1120
Step-by-step explanation:
Total number of audience members = 1600
30% of the audience were teenagers.
It means 70% of the audience were not teenagers. It can be given by :
x = 70% of 1600
Hence, 1120 audiences were not teenagers.
Answer:
Option (4)
Step-by-step explanation:
Proportional relationship means,
y ∝ x
y = kx
Here, k = proportionality constant
Therefore, if the graph of a line passes through the origin (0, 0) table will represent the proportional relationship.
From table 1,
For a point (1, 2)
For another point (3, 2)
In both the cases 'k' is not same of constant.
Therefore, table (1) is not proportional.
For table (2),
Line passes through (2, 0).
That means there is a x-intercept → (2, 0)
Therefore, table doesn't represent a proportional relationship.
For table (3),
Line passes through a point (0, 1)
It means given line has a y-intercept → y = 1
Therefore, table doesn't represent a proportional relationship.
For table (4),
Line of this table passes through two points (1, 3) and (2, 6)
Therefore, proportionality constant for the given table is 3.
Now we can graph table (4).
