Like I said above, There were 40 rolls, 6 of which were a two (6/40) and 8 of which were a 4 (8/40). Simply add these together to get 14/40 as the probability of rolling a 2 or 4. This simplifies to 7/20
Answer:
Answer below, however this question is worded weirdly
Step-by-step explanation:
x(x - 0.37 ) = 12.6
simplify the equation
x^2 - 0.37x = 12.6
x^2 - 0.37x - 12.6 = 0
1.76
Subtract 2.5 to 3/4 by dividing 3 to 4 getting the answer of 1.76
Step-by-step explanation:
First we must calculate the interquartile range (IQR), using this equation:

Based on the information provided we fill in:


In order to find what the range for the data set is we need to use the Interquartile Rule:
× 
× 
×
Now we plugin in:


Any number below 25.5 is a possible outlier and any number above 77.5 is a possible outlier.
Answer:
Based on the results of the calculations, 25 could be a possible outlier in the data set.
.28 or 28% chance the randomly selected student is a senior. There are 50 total students in the band, and 14 seniors, so the probability that a senior is randomly selected is 14/50 or .28
