Answer:
answer is
x1= 1/2 + 1/2 * i *sqrt(5)
x2= 1/2 - 1/2 * i *sqrt(5)
Step-by-step explanation:
Please refer to the attached picture for the procedure
Keep in mind, that the first step to use the quadratic formula is to rearrange the terms.
Answer:
4.4
Step-by-step explanation:
Data set = 79, 93, 92, 86, 90
Xmean = (79 + 93 + 92 + 86 + 90)/5
= 440/5
Xmean = 88
MAD =
(79 - 88) + (93 - 88) + ( 92 - 88) + ( 86 - 88) + ( 90 - 88)/ 5
=
(9) + (5) + (4) + (2) + (2)/ 5
=
22/5
Mean Absolute Deviation = 4.4
I believe the product is 5x. Hope that helps :)
Answer:
Interest Rate : 0.0346 or 3.46%
Step-by-step explanation:
• 429.2=350*(1+x)^6
• 429.2/350= (1+x)^6
•(429.2/350)^(1/6)= 1+x
•(429.2/350)^(1/6)-1= x
Check work:
350*(1+0.0346)^6=429.2
