The range of the data:25, 81, 20, 22, 16, 6, 17,15,12, 30, 32, 10, 91, 8, 11, 20 is
sergiy2304 [10]
Answer:
85
Step-by-step explanation:
The range is defined as the difference between the highest observation and lower observation in a data.

Range of the data= Highest observation - Lower observation
=91-6=85
Answer:
x=-3/5
Step-by-step explanation:
3(x + 5) = 2(4x + 9)
First, distribute:
3(x)+3(5)=2(4x)+2(9)
3x+15=8x+18
-5x= 3
x= -3/5
Answer:
s = 6 cm
Step-by-step explanation:
The area (A) of an equilateral triangle is calculated as
A = ( s is the length of side )
Here A = 9 , thus
= 9 ( multiply both sides by 4 to clear the fraction )
s² = 36 ( divide both sides by )
s² = 36 ( take the square root of both sides )
s = = 6
