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.

Use distributive property:
(a + b)(c + d) = ac + ad + bc + bd
(y + 1)(y² + 2y + 3) = (y)(y²) + (y)(2y) + (y)(3) + (1)(y²) + (1)(2y) + (1)(3)
= y³ + 2y² + 3y + y² + 2y + 3 = y³ + (2y² + y²) + (3y + 2y) + 3
= y³ + 3y² + 5y + 3
Answer:
54
Step-by-step explanation:
48 / 8 = 6
48 + 6 = 54
Answer:
∠6 = 70°
Step-by-step explanation:
given that the lines are parallel
∠1 and ∠2 form a straight angle, hence
∠1 + ∠2 = 180°
110° + ∠2 = 180° ( subtract 110 from both sides )
∠2 = 70°
∠2 and ∠6 are corresponding angles and congruent, hence
∠6 = ∠2 = 70°
