The best prediction of the total number of tagged salmon in a sample of 2000 is 100.

<h3><u>Predictions</u></h3>

To determine what is the best prediction of the total number of tagged salmon in a sample of 2000, the following calculation must be performed:

  • 800 = 40
  • 2000 = X
  • 2000 x 40 / 800 = X
  • 80000 / 800 = X
  • 100 = X

Therefore, the best prediction of the total number of tagged salmon in a sample of 2000 is 100.

A farmer was asked how many cows and chickens she has. The farmer replied, "between the cows and the chickens, there are 162 eye
Kazeer [188]
<h2>☀️ <u>Solution</u><u>:</u></h2>

We all know that,

  • All animals have 2 eyes.
  • All cows have 4 feet
  • All hens have 2 feet

So, Let the no. of cows be x and chickens be y

According to question,

  • Total number of eyes = 162

Framing equation,

⇛ Eyes of cows + Eyes of chickens = 162

⇛ 2x + 2y = 162

⇛ 2(x + y) = 162

⇛ x + y = 162/2 = 81 -----------(1)

According to question(Cond.-1)

  • Total number of feet = 270

Framing equation,

⇛ Feet of cows + Feet of chickens = 270

⇛ 4x + 2y = 270

⇛ 2(2x + y) = 270

⇛ 2x + y = 135 ----------(2)

Subtracting eq.(1) from eq.(2),

⇛ 2x + y - (x + y) = 135 - 81

⇛ 2x + y - x - y = 54

⇛ x = 54

Putting value of x in eq.(1),

⇛ 54 + y = 81

⇛ y = 81 - 54

⇛ y = 27

⚘ So, Total number of animals,

  • Number of cows = x = 54
  • Number of chickens = y = 27

Hence, solved !!
