Q1=3 Q2[median]=12 Q3=14 and the IQR is 11
Answer:
B. 97%
Step-by-step explanation:
20 students is -2 standard deviations away from the mean
35 is +3 standard deviations away from the mean
100 - 2.4 = 97.6
(2.4 is amount of data we are not using)
please refer to the standard deviation graph attached :)
D. 5x+5y=10
The other 3 could be simplified further and have no y value.
Hope that helps
