The answer is:

3 : 500 = x : 12000

x = (3*12000)/500

x = 36000/500

x = 72

72 light bulbs are expected to be defective when 12000 are produced.

$~~~\text{Area of triangle} = \dfrac 12 \times \text{Base} \times \text{Height}\\\\\implies 10 = \dfrac 12 \times 5 \times w\\\\\implies w =\dfrac{20}5 \\\\\implies w = 4 ~cm$

Use the rule of 70 to estimate the time it will take an initial quantity to drop to half its value when h(x)=20*0.97^x, where x

Gre4nikov [31]

The rule of 70 is used to estimate the time it will take an initial quantity to drop to half its value:
70 : (the decreasing rate) = x ( months )
The decreasing rate = 1 - 0.97 = 0.03 = 3%
x = 70 : 3 = 23.33 = 23 1/3 = 23 months and 10 days.
Verify:
20 * 0.97^(23.33) = 9.83 ≈ 10
