No because they aren't Fair
Answer:
The speed of the car is 67.77 m/s and it is moving away from the observer.
Explanation:
The apparent frequency is given as
![f' = f\dfrac{ [v - vo]}{ [v - vs]}](https://tex.z-dn.net/?f=f%27%20%3D%20f%5Cdfrac%7B%20%5Bv%20-%20vo%5D%7D%7B%20%5Bv%20-%20vs%5D%7D)
Here
o is the observer
s is the source which is car
v is the speed of sound = 343 m/s
f = true frequency emitted by the car (when stationary)
f ' = 0.835 f
so
![f' = f\dfrac{ [v - vo]}{ [v - vs]}\\0.835 f= f\dfrac{ [v - vo]}{ [v - vs]}\\0.835 = \dfrac{ [343 - 0]}{ [343 - vs]}\\0.835=\frac{343}{343-x}\\x=-67.77 m/s](https://tex.z-dn.net/?f=f%27%20%3D%20f%5Cdfrac%7B%20%5Bv%20-%20vo%5D%7D%7B%20%5Bv%20-%20vs%5D%7D%5C%5C0.835%20f%3D%20f%5Cdfrac%7B%20%5Bv%20-%20vo%5D%7D%7B%20%5Bv%20-%20vs%5D%7D%5C%5C0.835%20%3D%20%5Cdfrac%7B%20%5B343%20-%200%5D%7D%7B%20%5B343%20-%20vs%5D%7D%5C%5C0.835%3D%5Cfrac%7B343%7D%7B343-x%7D%5C%5Cx%3D-67.77%20m%2Fs)
The speed of the car is 67.77 m/s and it is moving away from the observer.
Answer:
$2700 supplies in hand
$3600 Supplies expense
Explanation:
As you can see in question data Sheldon has already counted the supplies in hand so, we only have to calculate supplies expense by doing some minor workings
WORKINGS
Supplies Expense = Opening + purchases - payment made
Supplies Expense = $1600 + $4700 - $2500
Supplies Expense = $3600
Answer:
TRUE - Analytics
Explanation:
Analytics is the systematic process of finding, interpreting and communicating meaningful patterns found in data. Ot involves the examination of data using mathematical methods.
The online retailer used analytics in order to understand the consumers behaviors and then to be able to make decisions from result gotten rather than the use of "gut" feeling or intuition which isn't backed by data or facts.
The use of analytics in business making decisions generally improves profits margins, efficiency and risk management.
