Answer:
0.8 / 0.5
Step-by-step explanation:
Given :
Deviations of Rainfall :
______Last Week ____ This Week
Mean___ 3.5 in. ________2.7 in
MAD ___ 1.2 in _________ 0.5 in
Mean difference = 3.5 in - 2.7 in = 0.8 in
This week's mean absolute deviation = 0.5 in
Mean difference / this week's mean absolute deviation
= 0.8 / 0.5
Answer:
- <em>The next number in the series 100, 96, 104, 88, 120, 56, ... is</em>: <u>184</u>
Explanation:
1) You need to try to find a pattern in the given sequence, so that you can conclude a rule to determine each number in the sequence.
2) The first logical approach to find such pattern is to find the differences between any pair of consecutive numbers. That leads you to this:
3) From that, you can see that the difference between two consecutive numbers is scaled by a factor of - 2. That is shown here:
- Second difference = 8 = - 4 ( - 2)
- Third difference = - 16 = 8 (- 2)
- Fourth difference = 32 = - 16 ( - 2)
- Fifth difference = - 64 = 32 ( - 2)
4) Therefore, in words, the rule is "add (- 2) times the previous difference", which is:
⇒ 56 + 128 = 184.
⇒ Answer: the next number is 184.

Answer:
The interquartile range is 12.
Step-by-step explanation:
In a box-and-whisker plot, the left edge of the box is the lower quartile and the right edge of the box is the upper quartile. The line dividing the box is the median. The end of the left whisker shows the minimum value. The end of the right whisker shows the maximum value.
In your question, the lower quartile is 29, the upper quartile is 41, while the median is 32. The minimum value is 10 and the maximum value is 51.
The formula for the interquartile range is as follows:
Interquartile Range = Upper quartile - Lower quartile
In this question, interquartile range = 41 - 29 which equals 12. Hence, the answer is 12.
