What is the mode of the data set?

61, 92, 61, 89, 92, 61

what is the mean of the data set?

82, 105, 247, 119, 94, 202

at sara's new job she spent $11.52, $6.48, $5.99, $14.00, and $9.50 on lunch the first week.

in the second week, she spent $4 more in total for the 5 lunches than the first week.

what is the increase in the mean for the second week compared to the first?

round the answer to the nearest penny.

a class of 25 students took a spelling test. two students scored 100 on each test, nine students scored 95 on each test, ten students scored 90 on each test, three students scored 80 on each test and one student scored 70.

what is the average score of the spelling test rounded to one decimal place?

1) 61, 92, 61, 89, 92, 61

Mode : The number which appears most often in a set of numbers.

61 occurred thrice

89 occurred once

92 occurred twice

Since 61 occurred most often

So, Mode of the given data is 61.

2)82, 105, 247, 119, 94, 202

Mean =

So, Mean =

Mean =

Thus the mean of the given data is 141.5

3) First week expenditure:  $11.52, $6.48, $5.99, $14.00, and $9.50

Mean =

So, Mean =

Mean =

Now we are given that in the second week, she spent $4 more in total for the 5 lunches than the first week.

So, Mean =

So, Mean =

Mean =

Increase in the mean in the second week = 8.581-7.915 = 0.666

Hence the increase in the mean for the second week compared to the first is 0.666.

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
