(PLEASE HELP) A teacher surveyed a sample of students from Lake Middle School. He asked the students where they'd like to go for a field trip. He recorded these results:

• 80 chose the aquarium.

• 60 chose the science center.

• 30 chose the planetarium.

• 40 chose the farm.

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

(he surveyed 210 students and about 38% of them chose the aquarium)

Write and solve a proportion that the teacher can use to estimate how many students in the whole school would choose the aquarium.

Answer:

relative frequency of choosing aquarium is 80/210

about 400 students out of 2000 will choose aquarium

Step-by-step explanation:

relative frequency of choosing aquarium is 80/210

proportion:

a = students who choose aquarium

80/210 = a/1000

210a = 80000

a = 80000/210 which is close to 80000/200 which equals 800/2 or about 400 students
