Answer:
X= -0.4545
Step-by-step explanation:
YOU HAVE TO SUBTRACT .2Z FROM .4Z WHICH GETS YOU .2 ON THE RIGHT SIDE
THAT WOULD MEAN YOU HAVE TO CLEAR OUT THE SEVEN BY ADDING IT ON BOTH SIDES GETTING -1
THEN YOU WOULD HAVE -1=.2Z
THEN DIVIDE BY .2 GETTING YOU A TOTAL OF -0.4545 WHEN YOU FINISH DIVIDING

Answer:
A = P(1 + r/100)^n
A = 1000 x (1.08)^n
Step-by-step explanation:
n is the number of years, p is the principal, A is the amount.
The lamp is appreciating (increasing in value) so every year, its value is 1.08 times its value the year before.
Use the first equation to be more general, use the second equation if there isn't anything below asking you to input numbers into the equation.
Probably just use the first one.
Answer:
<h2>The mean is 26666.67 and the standard deviation is 372919430.33.</h2>
Step-by-step explanation:
The mean means the average of the numbers.
The mean will be 
.
The differences of the earnings from the mean are 1666.67, 26997.33, 33997.33.
Squaring the numbers we get, 2777788.89, 728855827.13, 1155818447.12.
We need to find the mean of the above numbers to get the standard deviation.
Thus, the standard deviation is 
.
