Which marine fish stock assessment method involves trawling by scientists to collect data, which are then used to infer changes in the status of a marine fish stock from year to year?

add the table and i will answer correctly

step-by-step explanation:

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

final total: 63

step-by-step explanation:

60 times sales tax

60 times 0.05

3

60 + 3

63

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
