Gnom [1K]3 years ago
3 0

Step-by-step explanation:

First we must calculate the interquartile range (IQR), using this equation:

IQR = Q_{3} - Q_{1}

Based on the information provided we fill in:

IQR = 58 - 45

IQR = 13

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

Q_{1}-1.5 × IQR\\

Q_{3}+1.5 × IQR\\

1.5 × 13 = 19.5

Now we plugin in:

45 - 19.5 = 25.5\\

58 + 19.5 = 77.5

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.

HELP PLEASE ILL GIVE 27 POINTS <br> 120% of x is 96. What is x?
zlopas [31]

Answer:

Step-by-step explanation:

You can do this using a small equation.

120% x = 96                    Change 120% to a decimal

120/100 * x = 96             Multiply by 100

120x = 96 * 100

120x = 9600                   Divide by 120

x = 9600/120

x =  80

Look what you got. 20% more than 80 is 96. x is smaller than 96.

If you take 20/100 * 80 = 16

if you add 16 to 80, you  get 96
