Step-by-step explanation:
<h3>Definitions</h3>
- Mean - average number
- Median - the middlepoint of the data set
- Mode - the most repeated data in the set
- Range - the difference between the minimum and maximum values of data set
- First quartile - Q1, the median of the lower half of the data set
- Third quartile - Q3, the median of the upper half of the data set
- IQR - the difference of Q3 and Q1
<h3>Step 1</h3>
Put the data in the ascending order
- a) 1, 3, 5, 6, 7, 7, 8, 9, 10, 11, 11, 12, 12, 14, 16, 16
- b) 5, 7, 7, 8, 9, 10, 10, 85, 90, 95, 105, 115
<h3>Step 2</h3>
Find all the numbers
a)
- Mean = (1+3+ 5+ 6+ 7+ 7+ 8+ 9+ 10+ 11+ 11+ 12+ 12+ 14+ 16+ 16)/16 = 9.25
- Median = (9 + 10)/2 = 9.5
- Mode = none
- Range = 16 - 1 = 15
- Q1 = (6 + 7)/2 = 6.5
- Q3 = 12
- IQR = 12 - 6.5 = 5.5
- The data is almost uniform as the mean and median are very close
b)
- Mean = (5+ 7+ 7+ 8+ 9+ 10+ 10+ 85+ 90+ 95+ 105+ 115)/12 = 45.5
- Median = 10
- Mode = none
- Range = 115 - 5 = 110
- Q1 = (7 + 8)/2 = 7.5
- Q3 = (90 + 95)/2 = 92.5
- IQR = 92.5 - 7.5 = 85
- The data is skewed left as the mean and median are too differenet
She gives away n books per week, so If
, then she has (
) books left at any time.
this will be the explicit formula.
so we need to write in terms of recrusive.
to be recrusive each term must be expressed in terms of previous term.
in this represent
} [/tex] in terms of ![a_{w}](https://tex.z-dn.net/?f=%20a_%7Bw%7D%20%20)
![a_{w} =100-n(w-1)](https://tex.z-dn.net/?f=%20a_%7Bw%7D%20%3D100-n%28w-1%29%20)
![a_{w+1} =100-n(w+1-1)](https://tex.z-dn.net/?f=%20a_%7Bw%2B1%7D%20%3D100-n%28w%2B1-1%29%20)
replace w+1 in place of w .
![a_{W+1} =100-nw](https://tex.z-dn.net/?f=%20a_%7BW%2B1%7D%20%3D100-nw%20)
.
. this will be the recrusive expression for number of books she left.
<h3>Total snow fall for three days is 8.75 inches</h3>
<em><u>Solution:</u></em>
Given that,
Snow fell over the past three days
![First\ day = 3\frac{2}{4}\ inches = \frac{14}{4}\ inches\\\\Second\ day = 3\frac{2}{4}\ inches = \frac{14}{4}\ inches\\\\Third\ day = 1\frac{3}{4}\ inches = \frac{7}{4}\ inches](https://tex.z-dn.net/?f=First%5C%20day%20%3D%203%5Cfrac%7B2%7D%7B4%7D%5C%20inches%20%3D%20%5Cfrac%7B14%7D%7B4%7D%5C%20inches%5C%5C%5C%5CSecond%5C%20day%20%3D%203%5Cfrac%7B2%7D%7B4%7D%5C%20inches%20%3D%20%5Cfrac%7B14%7D%7B4%7D%5C%20inches%5C%5C%5C%5CThird%5C%20day%20%3D%201%5Cfrac%7B3%7D%7B4%7D%5C%20inches%20%3D%20%5Cfrac%7B7%7D%7B4%7D%5C%20inches)
<em><u>What was the total snowfall for the three days?</u></em>
Total snowfall = first day + second day + third day
![Total\ snowfall = \frac{14}{4} + \frac{14}{4} + \frac{7}{4}\\\\Total\ snowfall = \frac{14 + 14 + 7}{4}\\\\Total\ snowfall = \frac{35}{4} \text{ or } 8.75\ inches](https://tex.z-dn.net/?f=Total%5C%20snowfall%20%3D%20%5Cfrac%7B14%7D%7B4%7D%20%2B%20%5Cfrac%7B14%7D%7B4%7D%20%2B%20%5Cfrac%7B7%7D%7B4%7D%5C%5C%5C%5CTotal%5C%20snowfall%20%3D%20%5Cfrac%7B14%20%2B%2014%20%2B%207%7D%7B4%7D%5C%5C%5C%5CTotal%5C%20snowfall%20%3D%20%5Cfrac%7B35%7D%7B4%7D%20%5Ctext%7B%20or%20%7D%208.75%5C%20inches)
Thus total snow fall for three days is 8.75 inches
