Answer:
9
Step-by-step explanation:
60 requests are made.
Spencer gets 25% of these requests. Convert this to a decmal (divide by 100) to get 0.25. 25% of 60 is:
So Spencer gets 15 requests. Now do the same process for Tanvi:
So Tanvi gets 6 requests. To find out how many more requests Spencer gets compared to Tanvi:
Therefore, Spencer gets 9 more requests than Tanvi.
B
This property dictates that you can add regardless of how the numbers are grouped.
Let us calculate the median; the 6th observation is 20, so it is 20. We need the 6th observation so that out of the 11 observations we have 5 above the median and 5 below (or equal). We also have that then Q1 is the median of the lowest 5 observations, hence 19 (14,16,19,19,20, the 3rd observation is 19). Similarly, we get that the median for the upper half of the observations, Q3 namely, is 22 (21,21,22,22,23, the 3rd observation is 22). Thus, the interquartile range is 3=Q3-Q1. According to our calculations, all observations are wrong.
Answer:
( 3x + 1 ) ( x - 1)
Step-by-step explanation:
The given fraction is three 'x' to the power of two that is minus from 'x' minus from four. Simplifying that into three 'x' to the power of two. After this three minus 'x' plus four 'x' minus four. By taking common values which is three 'x' multipled by 'x' and minus one adding the entire by the value four which is further multipled by 'x' and minus one. Finally we obtain our answer that is three 'x' plus one multipled the entire by 'x' and minus one.
3x^2-x-4
3x^2
-3x+4x -4
Take common
3x ( x - 1 ) + 4 ( x - 1 )
( 3x + 1 ) ( x - 1)
