Answer:640

Step-by-step explanation:

Since 15 out of every 75 fish are more than 30 cm long, the probability of finding a fish more than 30 cm is P(x > 30) = 15/75 = 1/5.

The probability of finding a fish 30 cm or less is P(x ≤ 30) = 1 - P(x > 30)

= 1 - 1/5

= (5 - 1)/5

= 4/5

Since we have 800 fish and the probability of finding a fish 30 cm or less is P(x ≤ 30) = 4/5, then the number of fish in the population that are 30 cm or less in length are 800 × P(x ≤ 30) = 800 × 4/5

= 160 × 4

= 640

So, 640 fish in the population are 30 cm or less in length

9/10 greater than 6/8
Citrus2011 [14]
Yes.

First, you find the fractions with common denominators: 9/10 is equal to 72/80 and 6/8 is equal to 60/80.

Since 72 is greater than 60, 9/10 is greater than 6/8.
