Answer:
Step-by-step explanation:
Suppose number is x
Following equation can be written from question statement
Simplifying it further
There is no sum for this geometric series. it diverges rather than converges due to the absolute value of the common ratio (r), which is -3, being 3. for a geometric series to have a sum (to converge), the absolute value of r must be less than 1.
(you find r by dividing a2/a1, a3/a2, etc.)
hope this helps
Answer:
y = number of wristbands of Type 2 at $8 each
Step-by-step explanation:
The number of wristband of Type 1=x
The number of wristband of Type 2=y
The total amount of money earned from selling these wristbands is given as:
Amount of Money collected=5x + 8y
Now Total cost for an item= Cost Per Item X Number of Item sold
Therefore:
8y = 8 X y =Cost Per Wristband of Type 2 X number of wristbands of Type 2
The variable y represents the number of wristbands of Type 2 which is sold for $8 each.
Answer:
<h2>40%</h2>
Step-by-step explanation:
Step one:
given data
expected customers= 1200
actual customers= 725
the percent error= (actual-expected)/expected
substituting the given values we have'
%error=725-1200/1200
%error=475/1200
%error=0.395
To the nearest tenth we have 0.4
%error=0.4*100
%error=40%
Hence the percent error is 40%
