The answer would be 6.25×10 to the power of 5
Answer:
A
Step-by-step explanation:
The slope is negative so the line is high on the left and low on the right, slanting downward
The distance between (x1, y1) and (x2, y2) is found using the Pythagorean theorem. It is ...
For your values of (x1, y1) = (6, 5) and d = 5, substituting into the formula gives
This matches the first selection.
60% of 20 quizzes = 60/100*20 quizzes = 12 quizzes
Amount of quizzes remaining = 50 quizzes - 20 quizzes = 30 quizzes
He passes 80% of those 30 quizzes, so
80/100 * 30 quizzes = 24 quizzes
So, he passed 12 quizzes from the initial bunch and 24 quizzes from the rest, which totals to 12 quizzes + 24 quizzes = 36 quizzes.
Then, you see that he passed 36 quizzes, out of the total 50 quizzes, so the ratio is 36 quizzes / 50 quizzes = 36/50, which when converted as a percentage is 36/50 * 100% = 72%.
Therefore, he passed 72% of the quizzes for the entire year.
