I think you're looking for two different responses. The pyramid's volume is 15 cubic centimeters. If its slant height rises by 4 centimeters and height by 2 centimeters, the new volume would be 21 cubic centimeters. Thus, the volume increases by 6 cubic centimeters, calculated as 21 - 15 = 6. The formula to determine the volume of a pyramid is V=1/3*(L*W)*H. I might not be correct.
Hi there!
To calculate the mean, we first need to sum all the scores and divide by the total number of tests.
85+93+78+90+88+97+88=619
619/7≈88.43
Mean≈88.43
Next, we will determine the median by arranging the scores in ascending order.
78,85,88,88,90,93,97
To find the median, we look for the middle score, which is 88.
Median: 88
Lastly, we identify the mode, which is the score that occurs most frequently. Here, 88 appears twice while the others appear once, making 88 the mode.
Mode:88
I hope this is useful!
