Mathematics
1 answer:
krok68 [10]3 years ago
5 0

Answer:

  522

Step-by-step explanation:

The assumption is that the proportion of tagged fish caught is the same as the proportion of all fish that were caught and tagged:

  (all fish)/(number tagged) = (sample size)/(number in sample tagged)

  all fish = (number tagged) · (sample size)/(number in sample tagged)

  all fish = 174 · 39/13

  all fish = 522

If all the assumptions are reasonable, the number of fish in the lake is estimated at 522.

Find the volume of the prism.
Zigmanuir [339]

Answer:

The correct answer is first option.  270 m³

Step-by-step explanation:

Formula:

Volume of prism = Base area * Height

Area of triangle = bh/2  where b - base and h - height

From the figure we can see that height of prism = 36 m

Base is a right angled triangle with base 5 m and height = 3 m

<u>To find the Base area</u>

Area of triangle = bh/2 = (3 * 5)/2 = 15/2 = 7.5

<u>To find the volume of prism</u>

Volume = Base area * height = 7.5 * 36 = 270 m³

Therefore the correct answer is first option . 270 m³
