Mrrafil [7]

Answer:

267 students

Step-by-step explanation:

Number of students in a team (t) is proportional to number of honor roll students (n)

Mathematically, t = kn (k is constant

When t = 12, n = 8

k = t/n = 12/8 = 1.5

When t = 400

n = t/k = 400/1.5 = 267 (to the nearest whole number)

Scientists want to know the total trout population in a part of Lake Michigan. They tagged and released 200 trouts back into the
blondinia [14]
The estimate would be 1200.

We will set up a proportion for this.  10 out of 60 of the sample were tagged, so that is the first ratio.  The 200 that were tagged would be in the numerator of the second ratio (10 was the portion tagged, and 200 is the portion tagged, so they both go on top).  We do not know the total number so we use a variable:

10/60 = x/200

Cross multiply:

10*x = 60*200
10x = 12000

Divide both sides by 10:
10x/10 = 12000/10
x = 1200
