$6f-12=-4f+6\qquad|\text{add 12 to both sides}\\\\6f=-4f+18\qquad|\text{add 4f to both sides}\\\\10f=18\qquad|\text{divide both sides by 10}\\\\\boxed{f=1.8}$

(1) A manufacturer of tires believes that their mean time to failure (MTTF) is 20 613 km. They also believe that time to failure

ELEN [110]

Answer:

a) The probability of falling in the warranty period is 11.6%.

b) The warranty period need to be 19771 km to ensure that no more than 5 per cent of tires fail in the warranty period.

Step-by-step explanation:

a) To fall within the warranty period, the tire has to fail before the 20,000 km.

To calculate the probability, we first calculate the z-value:

$z=\frac{X-\mu}{\sigma}=\frac{20000-20613}{512}= \frac{-613}{512}= -1.197$

Then, the probability of falling in the warranty period is:

$P(X$

b) To calculate this we have to go on from a P(z<z₁)=0.05. This happens for z=-1.645.

This corresponds to a value X of:

$X=\mu+z*\sigma=20613+(-1.645)*512=20613-842=19771$

The warranty period need to be 19771 km to ensure that no more than 5 per cent of tires fail in the warranty period.

If R = (5+T)P/3 then what is p?

Illusion [34]

Answer:

Step-by-step explanation:

R = (5+T)P/3

3R = (5+T)P

3R/ (5+T) = P

$P = \frac{3R}{(5+T) }$
