Answer:
<em>summation of five times negative three to the power of n from n equals zero to infinity</em>
Step-by-step explanation:
<u>Summation Notation
</u>
It represents the sum of a finite or infinite number of terms. Let's analyze the terms of the given succession:
5-15+45-135+...
If we take 5 as a common factor, we have
5(1-3+9-27+...)
The parentheses contain the alternate sum/subtraction of powers of 3. The odd terms are positive, the even terms are negative, thus the exponent must be n starting from 0 or n-1 starting from 1
The summation is then represented by
This corresponds with the option:
<u>summation of five times negative three to the power of n from n equals zero to infinity</u>
The histogram for the data is given at the end of this answer.
<h3>What is an histogram?</h3>
An histogram is a graph that shows the number of times each element of x was observed.
In this problem:
- The elements of x are given by the time in hours.
- The histogram shows the number of runners that finished the race in x hours.
Hence, the graph given at the end of this answer is the histogram.

Answer:
12 Tables.
Step-by-step explanation:
There are many ways you can solve this with, here is the simplest.
Lets make it as a statement, IF 1 table has 5 chairs THEN how many X tables have 60 chairs.
Make it simplier:
1 Table = 5 Chairs
X Tables = 60 Chairs
using the cross multiplication method you will get
5X = 60
Divide by 5
X = 12
Which means that the room has 12 tables.
