Answer:
120 students did Jada survey
Step-by-step explanation:
*<em> Lets explain how to solve the problem</em>
- The results of Jada survey are shown in this circle graph
# Communication tools Text messages 5/12
# Phone 1/5
# Emails 1/20
# Other messaging apps 1/3
- A total of 50 students said they favored text messages to
communicate with friends
- We need to find the total number of the students in Jada survey
- <em>Assume that the total number of the students in the survey is </em><em>x</em>
∵ The Communication tools Text messages expressed by a
fraction 5/12 of the circle graph
∵ The total of 50 students said they favored text messages to
communicate with friends
- That means The fraction of x equivalent to 50
∴
- Multiply both sides by 12
∴ 5x = 600
- Divide both sides by 5
∴ x = 120
∵ x represents the number of the students in Jada survey
∴ 120 students did Jada survey
Answer:
A:
Step-by-step explanation:
In this case it can be seen that the x values are being affected by this transformation. This means that we should look for points on f and g with the same y value but different x values. However in this case it is hard to pinpoint easy coordinates to work with. This is where process of elimination can help. We know it cant be B or C because if the dilation ratio is outside the function, the y values would be affected. That leaves it to A or D. We can see that g has shrunk from the original function. Shrinking along the x-values can be notated by the reciprocal of the factor of shrinking. In this case it looks like it shrunk down to half of the originals size. If we take the reciprocal of a half we get 2. Therefore if we plug that in we get:
