Answer:
The IQR of the data set is 4.5
Step-by-step explanation:
Given:
10 13 15 12 12 4 12 17
12 13 15 18 10 11 20 19
Now, to determine the IQR (interquartile range) of this data set.
So, <em>we need to set the data in numerical orders:</em>
4 10 10 11 12 12 12 12
13 13 15 15 17 18 19 20
Now,<em> we split this in half and get the medians of both half:</em>
<u>4 10 10 11 12 12 12 12 </u> Median 1 = 11.5
<u>13 13 15 15 17 18 19 20 </u> Median 2 = 16
Getting the medians of both half now we subtract the median 1 from median 2:
IQR = 16 - 11.5
IQR = 4.5.
Therefore, the IQR of the data set is 4.5
The number that each term of the equation be multiplied by to eliminate the decimals before solving -m+0.02+2.1m=-1.45-4.81m
It would be better to group all similar numbers.
<span>-m+0.02+2.1m=-1.45-4.81m
</span>-m + 2.1m + 4.81m = -1.45 - 0.02
5.91m = -1.47
The equation shown above, in order for us to eliminate the decimal,
we need to divide 5.91.
Answer:
12
Step-by-step explanation:
|-24 + 2|- 10
First do the absolute value
|-24 + 2|
|-22|
The positive value is 22
Replace the absolute value with 22
22-10 = 12
B is the correct. Because if you look at the problem I can turn it around and see
Answer:
Choice 4 (s - 3 = 12)
Step-by-step explanation:
I think you made a reading error on this question, as it said "for which equation is s = 9 <em>not</em> the solution?" No need to fret though, this can easily be solved by substituting 9 into the variable <em>s</em> of each equation.
1. We know it's not choice 1 (s + 6 = 15), because doing 9 + 6 does equal 15.
2. We know it's not choice 2 (7 + s = 19), because doing 7 + 9 does equal 16.
3. We know it's not choice 3 (13 - s = 4), because doing 13 - 9 does equal 4.
4. Choice 4 (s - 3 = 12) is the correct answer because doing 9 - 3 equals 6, not 12. Thus this equation is incorrect, meaning this is the correct choice.
Choice 4/D is the correct choice.
