How are the values of the eights related in 880?

1 answer:

7 0

In the number 880, the first eight is ten times that of the second eight. This is the first way in which the 8’s are related to one another. The second way that the two 8’s are related is that is that if the both 8’s change their respective places, then also the number will remain the same. Since in this case the number in the tens place and the hundreds place are same, so interchanging them will not have any effect on the overall number.

(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.

Least common denominator?

Over [174]

Answer:

$\large\boxed{(s-2)(s+2)(s-3)=(s^2-4)(s-3)=s^3-3s^2-4s+12}$

Step-by-step explanation:

$s^2-4=s^2-2^2=(s-2)(s+2)\\\\\text{used}\ a^2-b^2=(a-b)(a+b)\\\\s^2-5s+6=s^2-2s-3s+6=s(s-2)-3(s-2)=(s-2)(s-3)\\\\\text{Therefore}\ LCD(s^2-4,\ s^2-5s+6)=(s-2)(s+2)(s-3)$
