<span>A.The distributions are somewhat similar.
B.The means-to-MAD ratio is 4.
C.The distributions are different.
D.The means-to-MAD ratio is 3.
To get your answer </span>add all them together divide by 8.1 then multiply it to the second power.
Answer: a²+b² = -99/2
Step-by-step explanation:
Since we are given two equations, this equations will be solved simultaneously to get a² and b²
a³ - 3ab² = 47 ... 1
b³ - 3a² b = 52... 2
From 1, a(a² - 3b²) = 47...3
From 2, b(b² - 3a²) = 52... 4
Adding 3 and 4, we have;
a²+b²-3b²-3a² = 99 (note that a and b will no longer be part of the equations as they have been factored out)
a²+b²-(3b²+3a²) = 99
(a²+b²) -3(b²+a²)= 99
Taking the difference we have
- 2(a²+b²) = 99
a²+b² = -99/2
45 / 2 = 22.5
You can get 22.5 hours of Internet for 45$.
3-2*x is th answer hop it helps
<span>Evan rounded 4.8 down to 4. His estimate of 32 is too low.
I hope this helps, Good luck :)</span>
