Answer:
50 Questions
Step-by-step explanation:
14 out of 100 wrong gets 72% correct is equal to 28%
Compare the Score earned and a perfect score.
14/x = 28/100
1400=28x
50=x
Answer:
-28
Step-by-step explanation:
4 2/3=14/3
-6(14/3)=-2*14=-28
Answer:
y=1x or just y=x might be a good line of best fit for this data
Answer:
60°,60° and 60°.
Step-by-step explanation:
The sum of the interior angle of a triangle
=180°
So, let us test measured sets to get which of them could be the interior angles of a triangle.
The sum of the first measured set
= 90° + 42° + 58°
=190°
Also, the sum of the second measured set
= 60°+ 60° + 60°
=180°
The sum of the third measured set,
= 100°+ 48° + 43°
=191°
Finally, the sum of the fourth measured set
= 31° + 75°+ 70°
=176°
We can clearly conclude that, the measured set 60°,60°and 60° could only be the the set of interior angles of a triangle. Since it is the only set that add up to 180°
