A door alarm works in 72 out of 100 cases.
surveillance camera works in 68 out of 100 cases.
The probability that method A is used = 72/100
The probability that method B is used = 68/100
Since both method are used we find the probability of A and B
Probability ( A and B) = 
* 
= 
<span>f(x) = -6x +6
to find inverse
x = -6y + 6
6y = 6 - x
y = 1 - x/6
Answer
</span>f^–1(x)= 1 - x/6
The y intercept is 0, and the slope is 5x.
Equation: y = 5x +0.
14:35 is a ratio, and of-coarse, as we know, we can transform that into another way of writing a ratio:
14/35
Simplify
14/7 = 2
35/7 = 5
2:5
Answer: 2 to 5
