Louisiana biologists tagged 250 fish in the oxbow lake false river on october 5. on a later date, they found 7 tagged fish in a sample of 350 fish. estimate the total number of fish in false river to the nearest hundred.

at a school, the school population is 2/5 boys. there are 450 boys in the school. how many total students are in the school?

a bag contains quarter and dimes in a ratio of 3: 5. if there is $6 in quarters in the bag, how many dimes are there?

1. Set up a ratio:

7 tagged / 350 fish = 250 tagged / x fish

Solve for x:

x = (350 * 250) / 7

x = 12,500 fish

2. Divide number of boys by the population ratio:

450 / 2/5 =  (450 *5) /2 = 2250 / 2 = 1125 total students.

3.  4 quarters = $1, so they have 24 quarters total.

The ratio 3:5 means for every 3 quarters there are 5 dimes.

24 quarters / 3 = 8

8 x 5 = 40 dimes.

(1)  The population of fish in the False river is 12500.

(2) There are 1125  total number of students in the school .

(3) There are 40 dimes in the bag.

(1) Number of fish tagged by Louisiana biologists =  250

On the next day a sample was collected from the False river

The number of fish in the sample = 350

Number of tagged fish in the sample =  7

Let the population of fish in the False river  = P

Takin the ratio we can

So the population of fish in the False river = 12500

(2) The number of boys in the school = 450

Let the total number of students in the  school be B

According to the given condition

So the total number of students in the school = 1125

(3) Let the number of dimes in the bag be x

According to the given condition we can write

Also  it is given that there are $6 in quarters in the bag.

$1 = 4 quarters

So $6 has  

So we can put this value in equation (1)

So we can conclude that there are 40 dimes in the bag.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
