Step-by-step explanation:
draw a right angled triangle and use pythagoras to solve it
The interquartile range is 1.5
Q1 = 38 (between 34 and 43)
Median = 39
Q3 = 39.5 (between 39 and 40)
To get the interquartile range you find the difference with Q3 and Q1
39.5 - 38 = 1.5
Answer:
x = -9
Step-by-step explanation:
2x + 3 = x - 6
Add 6 to both sides of this equation
2x + 9 = x
Subtract 9 from both sides of the equation
2x = x - 9
Subtract 1x from both sides of the equation
x = -9
