Collin's sampling method will better represent the entire population.
<h3>Missing part of the question</h3>
Determine which sampling method will better represent the entire population.
<h3>How to determine the better method?</h3>
From the question, we understand the Collin selected random names from the school directory.
While Karl surveyed only the students sitting close to him.
Karl's method is biased because students sitting far from him do not have a chance of being surveyed.
Hence, Collin's sampling method will better represent the entire population.

Answer:
0.63
Step-by-step explanation:
I don’t know what your trying to find but you basically create an equation, like this
3x+5x=80
and solve which would result in x=10
so there is
30 geckos
and
50 anole lizards
Answer:
x = 9 is the x-intercept.
Step-by-step explanation:
We have given the coordinates (-6,10) and (12,-2).
We have to find the x-intercept of the line containing these points.
First we find the slope m by using these points.
We know that m = (y₂-y₁)/(x₂-x₁)
m = -2/3
The general form of the equation of line is :
y = mx + c
Where c is the y intercept.
Using the first coordinate to find c .
10 = (-2/3)(-6) +c
c = 6
So, the required equation is :
y = (-2/3)x+6
We have to find the x-intercept.
For this we put y=0
(-2/3)x+6 = 0
2/3 x = 6
x = 6(3/2)
x = 9 is the x-intercept.
