Answer:
Step-by-step explanation:
The input value at which f(x) = g(x) can be found by setting the right sides of each of those equal to each other and solving for x.
1.8x - 10 = -4 and
1.8x = 6 so
x = 3 1/3
The bold equation is the answer to the first part, and the second part is that x = 3 1/3
0.442
Step-by-step explanation:
Step 1 :
Given that 11% of the lights are defective.
So probability of a light randomly chosen is defective is .11
This implies probability of a light randomly chosen is not defective is 1 - .11 = .89
Step 2 :
In a pack of 5 light bulbs the probability that none of them are defective is (0.89)^ 5
Hence the probability that at least one of the light bulbs is defective is
1-(0.89)^ 5 = 1 - 0.558 = 0.442
Answer:
the correct answer is option C
