Answer: The correct option is (A) 80.
Step-by-step explanation: Given that students were asked in a survey if they like peanuts, cashews, walnuts or pecans the most and the results are shown in the bar graph.
We are to find the total number of students that participated in the survey.
From the bar graph, we note that
Number of students who like Peanuts = 15,
number of students who like Cashews = 30,
number of students who like Walnuts = 10
and
number of students who like Pecans = 25.
Therefore, the total number of students that participated in the survey is
Thus, altogether, 80 students participated in the survey.
Option (A) is CORRECT.
Answer:
The vertex is the point (6,-31)
Step-by-step explanation:
we have
This is a vertical parabola open upward
The vertex represent a minimum
Convert to vertex form
Complete the square
Rewrite as perfect squares
-----> equation in vertex form
therefore
The vertex is the point (6,-31)
