Corresponding angle postulate
Answer:
The new mean for the exam scores is 51
Step-by-step explanation:
the mean can be calculated using the formula
mean of scores = 
before the 20 points was added, the mean of the score was = 50.
Inserting this into the formula, we have:
50 = 
from this, we can compute the sum total of the scores as
sum total = 50 × 20 = 1000
when the extra 20 marks is added, the sum of the entire scores will be changed to 1000 + 20 = 1020.
Hence the new mean will be computed as (New Sum total of scores / Number of students)
=
= 51.
∴ The new mean of the scores is = 51

This question is incomplete; find the complete question with the attachment.
Franco made number of muffins = a dozen
A dozen muffins = 12 muffins
Number of muffins were burned = 2
Remaining muffins = 12 - 2 = 10
Franco served 7 of the remaining non-burned muffins,
Fraction of muffins served =
Remaining muffins = 3
Fraction of remaining muffins = 
Fraction of remaining non-burned muffins we can get from,

Option B is the correct equation.
