Answer: There are 104 silvery minnow population in the Rio Grande River.

Step-by-step explanation:

Since we have given that

Number of tagged silvery minnows = 54

Number of captured silvery minnows = 62

It includes 12 tagged silvery minnows.

So, Number of silvery minnows without tags = 62 -12 =50

So, Good estimate of the silvery minnow population in the Rio Grande River would be

$54+50\\\\=104$

Hence, there are 104 silvery minnow population in the Rio Grande River.

A scale model of an airplane has a length of 19 centimeters and a wingspan of 18 centimeters. The length of the real airplane is

deff fn [24]

The wingspan is 36 m.

Using a proportion to solve this, we write the scale factor as a ratio first: 19/38, since 19 is the size of the model's length and 38 is the real length. For the second ratio, we have 18 for the size of the model wingspan and x for the real wingspan:

19/38 = 18/x

Cross multiply:
19*x = 38*18
19x = 684

Divide both sides by 19:
19x/19 = 684/19
x = 36 m
