(p^2 - 5p + 4) - (4p^2 - 9p + 11)
= p^2 - 5p + 4 - 4p^2 + 9p - 11
= p^2 - 4p^2 -5p + 9p + 4 - 11
= -3p^2 + 4p - 7
The number of 0.4 liter glasses of water that will be poured in the pitcher is 13
From the information given, we are being told that a pitcher can hold a maximum amount of 5.2 liters of water.
If we are to use a 0.4 liter of glass to pour water in the pitcher, then the number of times we will use the glass to pour water in the pitcher can be estimated as:
Number of glass that can fill the pitcher = 5.2 liters/ 0.4 liters
= 13 glass

Answer: a) 15:26, and b) 15:11.
Step-by-step explanation:
Since we have given that
Number of graded tests = 15
Number of total tests = 26
Number of ungraded tests is given by

a) Proportion of all exams has Dr. Fitxgerald graded is given by
15:26.
b) Ratio of graded to ungraded tests is given by 15:11
Hence, a) 15:26, and b) 15:11.
