Answer:

32 people

Step-by-step explanation:

Looking at the graph, we can say that 40% of the people rode the bus. We also know that 80 people took the survey.

<u>Solution:</u>

40/100 x 80
=> 2/5 x 80
=> 2 x 16
=> 32 people

Hence, 32 people rode the bus.

PLEASE HELP!! I’m very confuse

Given:

A(16, 4)

B(34, 40)

Line segment AB partition in the ratio 1 : 5.

To find:

The coordinate of a point that partitions AB.

Solution:

Section formula:

$$P(x,y)=\left(\frac{m x_{2}+n x_{1}}{m+n}, \frac{m y_{2}+m y_{1}}{m+n}\right)$

Here $x_1=16, y_1=4, x_2=34, y_2=40$ and m = 1, n = 5

$$P(x,y)=\left(\frac{1\times 34+5 \times 16}{1+5}, \frac{1\times 40+5 \times4}{1+5}\right)$

$$P(x,y)=\left(\frac{ 34+80}{6}, \frac{40+20}{6}\right)$

$$P(x,y)=\left(\frac{ 114}{6}, \frac{60}{6}\right)$

$$P(x,y)=(19, 10)$

The coordinate of point that partitions the segment AB is (19, 10).
