Hey there :)
7. The graph is about favourite colors of the students. Which option is right?
A. Fewer than 30% chose red, yellow or orange
Let us see if it is true, for 30%, the choice should have been 3 out of 10 ( [tex] \frac{3}{10} [/tex] )
This is a false option since red is chosen by 90% of students
B. More than [tex] \frac{1}{10} [/tex] of students chose pink
Let us check if it is right, a total of 4 out of 10 chose pink
Therefore, it is a correct statement
( You do not have to try with C and D since we found the answer )
Your answer will be option B
8. 3 angle measures are given to be 2x°, 50° and ( 3x - 10 )°
Interior Angles in a triangle add up to 180°
Therefore, equate it to 180
2x + 50 + ( 3x - 10 ) = 180
Add like terms together
2x + 3x + 50 - 10 = 180
5x + 40 = 180
5x = 140
[tex] \frac{5x}{5}= \frac{140}{5} [/tex]
x = 28
Your answer will be option J
