Answer:
1. 5/3 cm
2. 10 in
Step-by-step explanation:
1. The length of a rectangle is 4 cm more than 3 times its width.
Let the length be L and the width B
Then,
L = 4 + 3B
If the area of the rectangle is 15 cm2
Area = LB = 15
B(4 +3B) = 15
3B² + 4B - 15 = 0
3B² - 5B + 9B - 15 = 0
B(3B - 5) + 3(3B - 5) = 0
(3B - 5)(B + 3) = 0
3B - 5 = or B + 3 = 0
B = 5/3 or -3
since B cannot be negative, B = 5/3 cm
2. The ratio of length to width in a rectangle is 2 ∶ 3.
Let the length be L and the width B
Then,
L/B = 2/3
2B = 3L, B = (3/2)L
when the area is 150 in2.
Area = LB = 150
(3/2)L² = 150
L² = 150×2÷3
L² = 100
L = √100
L = ±10
since the length cannot be negative, L = 10 in
Answer:
Mean Deviation = 5
Step-by-step explanation:
The numbers are given as;
8, 12, 12, 25, 10, 14, 4, 3, 22, 10
Mean = Sum of numbers / Population = 120 / 10
Mean = 12
mean deviation involves finding the sum of the absolute values of the differences between the individual elements and the mean. Then divding by the population.
Mean Deviation = |(8 - 12) + (12 - 12) + ( 12 - 12) + (25- 12) + (10- 12) + 14- 12) + (4- 12) + (3 - 12) + (22- 12) + (10- 12)
| / 10
Mean Absolute Deviation = 5
