Answer:
A
Step-by-step explanation:
A: This is the best choice. She will get a survey sample of many students from different grades and the sample will be random. This will give accurate and unbiased results.
B: This would only give results of students in a math class, so the results would be biased.
C: This would only be surveying seventh grade students, when there are also other grades in the middle school. This would not give accurate results.
D. The question states that Nicole is surveying opinions of students. Asking the teachers, especially only the teachers in one hallway, will definitely not help to find the opinions of students.
Therefore, the correct choice is A: Random students as they enter school
The x-intercept is the x-coordinate of a point where a graph intersects the x-axis and the y-intercept is the y-coordinate of a point where a graph intersects the y-axis. For example, (-4,0) -4 is the x-intercept and (0,6) 6 is the y-intercept
Answer:
58 ft.
Step-by-step explanation:
We will use trigonometry to find the distance.
We know that he is 29 ft above the ground (26, height of building, + 3, height of bird).
We use the angle 60 and we see that we have a known side which is adjacent to the angle. The side we are trying to find is the hypotenuse. We will be using cos because cos uses adjacent and hypotenuse sides of triangle.
cos60 = 29/x
cos60x = 29
29/cos60 = x
x = 58
He must fly 58 feet in order to get to the ground.
Sort of not really if it were it would be phrased if you take yesterday’s temperature and add 15 then you get today’s temp.
The answer is 4/5 all you do is rise over run
