Yes that’s completely true because of course you can’t say it is false
Answer and Step-by-step explanation:
a)
expected value for the difference in sample means=3.5-3.2=0.3
b)
standard deviation of the sampling distribution of the difference in sample means
=sqrt((0.5^2/40)+(0.8^2/40))
=0.1492
c)
z=(0.3-0)/0.1492
z=2.01
P(z>2.01)=0.0222
Answer: Since she reduced her daily commute time by 75%, her time now is 25% of her original. Thus, you have 0.25m or 25m%.
Step-by-step explanation:
Its 2.5 if both the numbers are under sqrt.
Energy and work energy is the capacity to do work or to produce heat. Internal energy is the sum of kinetic energy and the potential energy.
