Answer:
14
Step-by-step explanation:
Geometric mean = nth root (product of individual values of set of data)
from the question, n=2,
product of individual values of set of data= 2/5*490 = 196
Therefore Sqrt (196) =14
NB: As n is 2, we use sqrt, if n is 3, we use cube root and so on
Answer:
0.00375 inches
Step-by-step explanation:
Since the microscope makes the microorganism appear ×200 larger, that would mean we would have to divide by 200 to get the original size. 0.75/200= 0.00375.
The answer is 72,
Work-
2(10-24•1/4)+8^2
2(10-6)+64
2(4)+64
8+64=72
Oh yes I will help you ;))))))))))
