Answer:
-4
Step-by-step explanation:
you will have to replace the n with -7, that means,
(-7+5)2
when a number is beside a bracket, it automatically means multiply
you will have to solve the numbers in the bracket first
-7 +5 is equal to -2
then, -2 multiplied by 2 is equal to -4
Answer:12.33
Step-by-step explanation:
Step-by-step explanation:
Putting the value of r
3 ( 1/6) 2
So 3 × (1/6) = 0.5 × 2 = 1
First thing...put the numbers in order ...
9,10,11,12,12,13,14,15,15,16,17,18,18,19,20,22
Q1 (lower quartile) = 12
Q2 (median) = 15
Q3 (upper quartile) = 18
IQR = Q3 - Q1 = 18 - 12 = 6
range = (highest number - lowest number) = 22 - 9 = 13
