I think that
Every point is moved so that it is 2/3 as far from the y axis
should be the answer
Answer:
Step-by-step explanation:
1/9 of the camp means it has 9 parts the whole thing (each 1/9)
1/3 of an hour for 1 part and
for 9 parts we have
1/3 *9 = 9/3= 3 hours
Based on the dimensions of the wall and the triangular glass, the number of mirrors needed is 215 mirrors.
<h3>What number of mirrors are needed?</h3>
First find the area of the wall:
= 36 x 93
= 3,348 m²
The area of the triangle, assuming it is an equilateral triangle is:
= (√3/4) x 6²
= 15.59 m²
The number of mirrors needed is:
= 3,348 / 15.59
= 215 mirrors

Answer:
It shows that the survey is meaningless because of voluntary response bias.
Step-by-step explanation:
This survey in the question provides a very good example of voluntary response bias and this often overrepresents negative opinions. Now, the people who chose to respond were most likely parents who were very unhappy, and so, there is very little chance that the 10,000 respondents were representative of the population. Knowing more about her readers, or taking a sample of the sample, would not have helped.
Thus, we can conclude that ;The survey is meaningless because of voluntary response bias.
