Answer:
it is definitely negative, i think it is -3/2
Step-by-step explanation:
is there a better picture of the graph?
The saving plan balance is $3,677.53.
Given that,
- The no of months is 18.
- The annual percentage rate is 3% so the monthly rate percentage is 0.25%.
- And, the monthly payment is $200.
Based on the above information, the following formula should be used:
FVA = PMT× [(1+r)^n - 1] ÷ r
= $200 × [(1+ 0.0025)^18 - 1] ÷ 0.0025
= $3,677.53
Therefore we can conclude that the saving plan balance is $3,677.53.

Answer: 2n
Step-by-step explanation:
Silvia is n, sister is n, total is n+n=2n.
From the unit circle:
sin 30 = 1/2, cos 30 = √3 / 2, tan 30 = √3 / 3 , tan 60 = √3;
sin 30 * sin 60 = ( cos 60 * tan 30 ) * ( cos 30 * tan 60 )
Left side of an equation:
sin 30 * sin 60 = 1/2 * √3 / 2 = √3 / 4
Right side:
( cos 60 * tan 30 ) * ( cos 30 * tan 60 ) =
= ( 1/2 * √3 / 3 ) * ( √3 / 2 * √3 ) =
= √3 / 6 * 3 / 2 = √3 / 4
√3 / 4 = √3 / 4 ( correct )
Answer:
32.793
Step-by-step explanation:
Given that your marketing colleague used a known population mean and standard deviation to compute the standard error as 56.8 for samples of a particular size
You don't know the particular sample size but your colleague told you that the sample size is greater than 60.
When n becomes 3n, we get Std error would become instead of 
to 
Thus we get standard error for new sample size = old se/sqrt 3
=
