The question asks us to find the mean absolute deviation ( MAD ). We know that the mean is 3. First we have to find the distance of the each value from the mean ( and ignore minus signs ). For example: 1 - 3 = | - 2 | = 2 ( absolute value ) etc. Then we have to find the mean of their distance: MAD = ( 2 + 2 + 1 + 1 + 0 + 0 + 0 + 1 + 2 + 3 ) / 10 = 12 : 10 = 1.2. Answer: The mean absolute deviation is <span>A ) 1.2.</span>
p=15250
r=7.5/100=0.075
y = 15250*(1 - 0.075)^x
after 8 years it would be
x = 8
y = 15250*(1 - 0.075)^8
y = $8,173.42
after 8 years the value of the car is going to be $8,173.42
<em>429 cm²</em>
- Step-by-step explanation:
<em>A(blue) =</em>
<em>= 2×6cm×10cm + 2×6cm×8cm + 8cm×10cm + (8cm×10cm - 5cm×4cm)</em>
<em>= 120cm² + 96cm² + 80cm² + 60cm²</em>
<em>= 356 cm²</em>
<em>A(green) =</em>
<em>= 4cm×5cm + 2×5cm×5cm/2 + 4cm×7cm</em>
<em>= 20cm² + 25cm² + 28cm²</em>
<em>= 73 cm²</em>
<em>A(total) =</em>
<em>= A(blue) + A(green)</em>
<em>= 356 cm² + 73 cm²</em>
<em>= 429 cm²</em>

Since logs can't equal zero, 5 is your only solution.
B. 6:12 is the answer (times the first number by 2 to get the second number)
