Answer:
The quotient of 4 and 9 raised to the power of r.
Step-by-step explanation:
To find the Mean or Average you have to add up all numbers it is asking for which in case are 222 and 198.
so you will add 222+198
That will equal 420
Then you will divide with the amount added together which is 2
420/2=210
so the mean of the 11 people is 210 or 210lbs
I=$52,000
R=6.75%
T=5.5 years
P=$19,305
The answer is b
2cos x + 1 = 0
2 cos x = -1

x = cos^1(-1/2)
(cos inverse (-1/2))
x = 120°
