Answer:
A=5×10-5m²
Step-by-step explanation:
Unit Conversion:
d=0.01m
Using the formulas
A=a2
d=2a
Solving forA
A=1
2d2=1
2·0.012=5×10-5m²
Answer:
A. 0.020
Step-by-step explanation:
we calculate the standard error of the sample mean with the formula,
,
with E= standard error of the sample mean
s= standard deviation
n= sample
So,
s= 0.2
n= 100
Answer:
Domain: - 9, - 4, 3, 9
Range: 2
Step-by-step explanation:
The domain is the first coordinate of an ordered pair. This means that the domain is going to be x. The range is the second coordinate of an ordered pair. This means that the range is going to be y. Since all of the second coordinates are 2 you only have to put 2 once. The domain of the set of ordered pairs is - 9, - 4, 3, 9.
