Answer:
Step-by-step explanation:
A geometric series is one where each term is multiplied by a constant value known as r to get the next term
Sum of n terms of a geometric series is
Sum of infinite series is obtained as the limiting value of this sum when n tends to infinity
We find that only when |r|<1, r power n tends to 0 as n tends to infinity.
Other r power n diverges.
Hence geometric series infinite sum formula is valid only when
|r|<1 since the series sum converges to a finite value
Answer:
6.5
Step-by-step explanation:
The midpoint of the line is (-1,7). If you draw a line between that and (1.6), you’ll pass through the y-axis at 6.5.
This is a fun problem! Just graph the two equations, then see what points the line intersects with the parabola. Or, set the two equations equal to each other, and solve for the two intersecting points.
Solve for x and y: -2x+8 = x-2.23y+10.34
Answer:
9,240
Step-by-step explanation:
For the first number, there are 22 numbers available to choose from. For the second number, there are 21 numbers available, since the first number cannot be the same as the second number. And for the last number, there are 20 remaining numbers to choose from. So, there are 22*21*20=9240 possible sequences.
Answer:
Step-by-step explanation:
Looking at the graph, we can say that 40% of the people rode the bus. We also know that 80 people took the survey.
<u>Solution:</u>
- 40/100 x 80
- => 2/5 x 80
- => 2 x 16
- => 32 people
Hence, 32 people rode the bus.
