Step-by-step explanation:
Answer:
For both sets of data, the median is equal to the mean.
The interquartile range (IQR) is greater for M's classes than J's classes.
Step-by-step explanation:
<u>J's Classes:</u>
23, 25, 27, 28, 32
Median: 27
Mean: 27
Mean Absolute Deviation: 2.4
Interquartile Range: 3
<u>M's Classes:</u>
20, 24, 26, 29, 31
Median: 26
Mean: 26
Mean Absolute Deviation: 3.2
Interquartile Range: 5
This is an arithmetic sequence because we are adding the same amount each time. In this case, we are adding -4 to each term to get the next term
17 + (-4) = 13
13 + (-4) = 9
9 + (-4) = 5
and so on. The starting term is 
The common difference is 
The nth term of the arithmetic sequence can be found by this formula
For instance, if n = 2, then,
which matches up with the second term listed.
Answer:
1. No
2. Yes
3. Yes
4. Yes
Step-by-step explanation:
In 1. the difference between each term is not constant.(it goes up by, 2, 4, 6)
2. The terms increase by the same amount(it all goes up by 3)
3. The terms decrease by the same amount(it all goes down by 5)
4. The terms increase by the same amount(it all goes up by 6)
answer: 22
15/7.5 = x/11
cross multiply
7.5x = 165
divide by 7.5 on both sides to get the x alone
7.5x/7.5 = 165/7.5
x = 22
the tree is 22 feet
sorry if it’s wrong
