1. Factor the expression
2. Since is placed in the denominator of the given expression, then
3. Now the expression can be simplified:
Intervals are given to us
19, 19, 27, 20, 27, 26, 25, 26, 18, 27, 20, 24, 19, 21, 27, 23, 21, 17, 22, 22
From the given data we need to create a frequency table
From 17 - 19 there are 5 numbers. they are 19,19,19, 18, 17
From 20 -22 there are 6 numbers . they are 20, 20, 21, 21, 22, 22
From 23 - 25 there are 3 numbers. they are 23, 24, 25
From 26 to 28 there are 6 numbers . they are 27, 27, 26, 26, 27, 27
Histogram is attached below
Answer: 1. 7
2. 100
3. 193.8
4. 0.8
5. 90.6
Step-by-step explanation:
1. Given the data 9,3,10,12,4,5,12,2
For finding the median we arrange it in ascending order
2,3,4,5,9, 10,12,12
Since the no of observations are even
∴ median =
=
=
=7
i.e. Median =7
2. Given the data
23, 95,100,23,100,100
Since the no 100 is repeated thrice i.e. the maximum no of times
∴ Mode=100
3.
Given the data
108, 305,252,113, 191
Mean=
=
=193.8
4. Money spent in the first week
= $11.52, $6.48, $5.99, $14.00, and $9.50
Total for the first week
=11.52+6.48+5.99+14.00+9.50
=$47.49
Now she spent $4 more in the second week
i.e.$47.49+4
=51.49$
Increase in mean =
=0.8
5.
Given
2 students scored 100 each
9 students scored 95 each
10 students scored 90 each
3 students scored 80 each
1 student scored 70
Total score of students =

The average score
=
=90.6
