PLEASE HELP ASAP!!!

A teacher surveys a sample of students from Lake Middle School. He asks the students where they’d like to go for a field trip. He records these results:

80 choose the aquarium.
60 choose the science center.
30 choose the planetarium.
40 choose the farm.

The teacher wants to figure out the relative frequency of a student choosing the aquarium. He will then estimate how many students out of all 1000 at the school are likely to choose the aquarium. Answer the questions to solve the problem.

2. What is the relative frequency of a student choosing the aquarium? Give your answer as a decimal rounded to the nearest hundredth. Show your work. Write your answer in the space below

3. Suppose the teacher surveys one student at random. Based on the survey results, what is the estimated probability that the student chooses the aquarium? Write your answer in the space below.

Answer:

2. 0.38

3. 8/21

4. 8:21

Can somebody Graph this For Me?
D. What is the vertex of the parabola? What are the x- and y-intercepts? Hint: Use your answer from Part a to identify the x-intercepts. Use your answer from Part b to identify the y-intercept. Use your answer from Part c to identify the vertex. (4 points: 1 point for each coordinate point)

The vertex is located where the squared term equals zero; that is, x=-17, y=-64 (-17, -64). If x=0, then the y-intercept is y (0,225); if x=-25 and x=-9, then the x-intercepts are (-25,0) and (-9,0).

E. Graph the parabola. Use the key features of the graph that you identified in Part d. (3 points)

Luz drives at an average speed of 60 miles per hour.
She has driven for 2 hours and has traveled a distance of 120 miles.

This situation can be represented with a linear equation written in point-slope form, where x represents the number of hours and y represents the number of miles.

Use this information to complete each statement about the linear equation
