Use Substitution or Elimination
1. pick one equation and solve for a variable
6p + 1m = 9
1m = 9-6p
m = 9 - 6p/ 1
m= 9-6p
2. substitute m into one of the equations given
4p + 2 ( 9-6p) = 10
4p + 18 - 12p = 10
4p - 12p = 10 - 18
-8p = -8 (divide both sides by -8)
p = 1
3. Insert p=1 into any of the equations
6p+1m = 9
6(1)+1m =9
6 + 1m = 9
1m = 9-6
1m= 3
m = 3
2 ft > -3 ft
The redfish is deeper than the hermit crab.
2q+18=-5q-3
2q+5q=-3-18
7q=-21
q=-3

The estimate of the population proportion of defectives is 0.05.
Given that,
There are 10 different samples of 50 observations, that is, total of 500 observations.
To find : The estimate of the population proportion of defectives
And total number of defectives from 500 observations is (5+1+1+2+3+3+1+4+2+3) = 25
Thus, the point estimate for the population proportion defectives will be,
=25/500=0.05
or just obtain the individual proportion of each sample and then take their average to obtain the same result.
Thus, the point estimate for the population proportion defectives will be 0.05
