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
Hence, there are 104 silvery minnow population in the Rio Grande River.
Answer:
156
Step-by-step explanation:
f(x)= 4^(2x) -100
Let x =2
f(2)= 4^(2*2) -100
= 4^4 - 100
= 256 -100
= 156
Answer:
The length is 15 and the width is 10
Step-by-step explanation:
Let l = length
w = l-5
We know the area is 150
A = l*w
150 = l ( l-5)
150 = l^2 - 5l
Subtract 150 from each side
0 = l^2 - 5l - 150
Factor
0= ( l+10) ( l-15)
Using the zero product property
l+10 =0 l-15=0
l = -10 l = 15
Since we cannot have a negative length
l = 15
w = 15-5 = 10
The length is 15 and the width is 10
