At Kirby Middle School, some students were surveyed to see which social
media app they used the most. The results are shown below.
App Number of Students
Face
8
Snap
22
Insta
20
Solve and explain how to calculate what percent of students used Snap the
most?

Answers

Answer:

Kirby Middle School

The percentage of students who used Snap the most is given as:

= 44%

Step-by-step explanation:

a) Data and Calculations:

App Number of Students

Face 8

Snap 22

Insta 20

Total 50

The percentage of Snap users = Number of Snap users/Total users * 100

= 22/50 * 100 = 44%

b) This represents the proportion of all the students surveyed about the use of social media app. Since 22 students used Snap out of 50, it means that 44% of the survey sample used Snap. This is against 16% (8/50) who used Face and 40% (20/50) who used Insta.

HELP ASAP! I’m very confused and need help! Thanks!

Answers

Answer:

Step-by-step explanation:

Ok so basically 3 is 153 degrees and every line is 180 degrees, so 180-153=27. So 3 and 2 make a line, 2 is 27 degrees and 4 and 3 make a line so that makes 4 -27 degrees. 1 is vertical to 3 and if 2 and 4 are 27 degrees and makes the lines with the other angles that equal 27 degrees then 1 is also 153 degrees.

Sorry if this is hard to understand. Good luck! :)

You then cross multiply to get 36=x^2, or +-6=x
