1 answer:
Answer:
675 total attendees at the conference.
Step-by-step explanation:
Let x represent total attendees at the conference.
We have been given that at a conference the organizer determined at 32% of the attendees were between the ages of 18 and 29. There were 216 attendees in this age range. We are supposed to find the total attendees at the conference.
To find the number of total attendees at the conference, we will set as equation where 32% of x is equal to 216.
Therefore, there were 675 total attendees at the conference.

Answer:
a) Median stays the same
b) Mean is decreased by $9
Step-by-step explanation:
The median is the number or the average of the two numbers that is in the middle of a sorted distribution of numbers,
Here the median number will be the 5th number counting from left or right from the sorted list of numbers. Therefor is is 891.
When 1027 is changed to 946 it will fall between 938 and 1002. So updated sorted list of numbers will now look like,
679, 715, 799, 844, 891, 917, 938, 946, 1002
Here also median will be the 5th number which will be equal to 891.
Therefore, , median will not change.
Mean is the value we get by taking the total value of the salaries and divide it by the number of employees.
In the initial case,
Mean =
When the salary is changed from $1027 to $946,
Mean=
Therefor we can see that Mean has decreased by $9.
Exponential functions are in the form 
, where <em>a</em> is the initial value, <em>b</em> is the growth rate (percent increase) + 1, and <em>x</em> is the number of time periods. Our initial value is 100, and we're given the growth rate + 1 (tripling is the same as increasing by 200%; 200%=2.0; 2.0+1=3). Therefore our function is 
.
