50% of the data values are greater than 45, it is calculated using the concept of box-whisker plot.
In a box-whisker plot as shown it is given in the picture ,
A rectangular shaped box with two lines with a vertical mark which denotes the minimum, first quartile, median , third quartile and maximum quartile.
It is used in descriptive statistics.
So as per the given question box-whisker plot represents some data set .There is a number 45 just corresponding to it there is a vertical line which shows that 45 is the median of the data and here 45 is the 50th percentile,
It means that there is 50 % values are greater than 45 and 50% values are greater than 45.
By this method we can quickly find out the percentage of data for which data the value is greater or lesser. It helps in analyzing the data and interpreting the results.
Hence 50% values are greater than 45.

Here is the answer in different forms
Answer:
The second table.
Step-by-step explanation:
In the first table, the speed goes from 45 down to 43; then down to 41; then up to 42; then up to 43. It decreases and then increases. This is not the correct table.
In the second table, the speed goes from 45 up to 47; then up to 49; then down to 48; then down to 47. It increases and then decreases; this is the correct table.
To verify, we check the last two tables. The third table stays at 45, then decreases to 43 and 41. This is not correct.
The last table decreases from 45 to 43, then decreases to 41, then stays constant. This is not correct.
The second table is the only correct one.
Answer:
7.83
Step-by-step explanation:
cos(40)=6/(ZX)
zx=7.83
So to do this all u have to do is find their WPM (words per minute). Just simply take their number of words and divide by their minutes.
Carl types 54 WPM
Max types 52 WPM
Jason types 59 WPM
So the answer is Max-Carl-Jason
Hope this helped
