7, 5, 1, 6, 2 Mean Absolute Deviation = 2.16
3, 6, 3, 2, 1 Mean Absolute Deviation = 1.2
60 divided by 70 and multiplied by 100 to get your answer
Answer:
9.76
Step-by-step explanation:
area of a rectangle = length * breadth
length = (2x + 3)
breadth = x
given area is 220 sq. inches.
thus,
220 = x * (2x+3)
220 = 2x² +3x
2x² + 3x -220 = 0
x = (-b + √ ( b²-4ac) ) ÷ 2a
x = ( -3 + √ ( 3² - 4*2*220) ) ÷ 2*2
x =9.76
The answer is 9.
