Answer:
16. 5.1b + 0.8
17. x
Step-by-step explanation: All you have to do is add the common values 3.2b and 1.9b
Answer:
This means that 12 is the slope of the line y = 12x - 19.
Complete question:
A manufacturer has determined that a model of its washing machine has an expected life that is Exponential with a mean of four years to failure and irrelevant board burn-in period. He wants to testthe system and complete data collection. Find the probability that one of these washing machines will have a life that ends: (Note you can find the reliability of the washing machine life)
a) After an initial four years of washing machine service
b) Before four years of washing machine service are completed
c) Not before six years of washing machine service.
Answer:
a) 0.3679
b) 0.6321
c) 0.2231
Step-by-step explanation:
Given:
Mean, u= 4
/\ = 1/u
= 1/4 = 0.25
The cummulative distribution function, will be:
For x≥0,


a) After an intial four years:

P(x>4) = 0.3679
b) Before four years:

P(x<4) = 0.6321
c) Not before 6 years:

P(x>6) = 0.2231
Answer:
x = 0
Step-by-step explanation:
4(x+3)-8 = 2(x+2)
4x+12-8 = 2x+4
4x+4 = 2x+4
-2x -2x
2x+4 = 4
-4 -4
2x = 0
x = 0
Hope this helps!
Answer:
sin A = opp/hyp = 15/17
Right triangle
Therefor
a² + b² = c²
adj² + opp² = hyp²
adj² + 15² = 17²
adj² = 17² - 15²
adj² = 289 - 225
adj² = 64
adj = 8
Cos = adj/hyp
cos A = 8/17 <–––––
