Ответ:
Mean = 15.83 hours
Median = 17 hours
Step-by-step explanation:
The first step to follow when dealing with data distributions is to arrange the data in either an ascending or descending order.
Once this is done, we have the responses as
responses: 9. 14, 16, 18, 19, 19
The mean of the distribution can be obtained by dividing the total sum of the values, by the number of respondents.
this is
The mean of the distribution is 15.83 hours
The median is obtained by picking out the middle number of the distribution. However, our distribution is even, and hence has two middle numbers. To solve this , we simply add the two numbers and divide by 2
= (16 + 18 )/2 = 34/2 =17
Ответ:
fg=16
step-by-step explanation:
set both of the equation equal to each other;
2n-6=n+5
add 6 to both sides of the equation;
2n=n+11
subtract n from both sides of the equation;
n=11
plug the value of n into the equation and solve;
2(11)-6= 16
hope this , have a blessed day : )
