Answer:

A. 0.020

Step-by-step explanation:

we calculate the standard error of the sample mean with the formula,

E=\frac{s}{\sqrt{n} },

with E= standard error of the sample mean

s= standard deviation

n= sample

So,

s= 0.2

n= 100

E=\frac{0.2}{\sqrt{100} } =\frac{0.2}{10}=0.02

raketka [301]
Let named variables as you said g- guinea pigs and c- chinchillas
System of equation is:

First is:   c+ g = 60,005 
Second is:   c= 2g+5

When we replace second in first we get:

2g+5+g = 60,005 => 3g+5= 60,005 => 3g= 60,000

g=60.000/3 = 20,000 => g=20,000

When this result we replace in the second equation we get

c= 2 * 20,000 +5= 40,000+5 = 40,005

c= 40,005

Good luck!!!!
