Answer:
Q3-Q1=IQR
Step-by-step explanation:
Arrange the numbers from least to greatest then find the median of the whole set. After finding the median separate the lower half and the upper half of the data. Then find the median of the upper and lower half. The median of the lower is called the Q1 and the median of the upper half is called Q3. Finally, subtract Q1 from Q3 and this equals the IQR interquartile range).
Answer:
B, between 2.8 and 2.9
Step-by-step explanation:
it is exactly 2.828427125
First take the exponent and 'kill' the 2, by - it from the 3, which gives you just 2x1 (Sorry can't make the one an exponent on this.). Then you take the 2x and times it by itself, so that you end up with 4x. Now you add the 4x and the 5x, to give you 9x. Then -5x from the 9x. to give us 4x again. Now you minus the 2. so that we have 4x-16 dived by x=? from there you dived 4x by 1x to give you 4x. Then you add the -16 over. so that you have 4x=16, then just dived 16 by 4. In the end x=4.
