The probability that a transmission will last less than 14 years is 5%

Step-by-step explanation:

Given

Mean = 16 years

SD = 1.2 years

We have to find the probability that a transmission will last less than 14 years

First of all we have to find the z-score of the value

Z-score is given by:

z = \frac{Value-mean}{SD}\\= \frac{14-16}{1.2}\\= \frac{-2}{1.2}\\= -1.6666

We will use the z-score table to find the probability of being less than 14

So,

From z-score table we get the value for -1.6666

P(z = -1.666) = 0.04846

Converting into percentage

= 0.04846* 100

= 4.846

Rounding off to nearest percentage

5%

Hence,

The probability that a transmission will last less than 14 years is 5%

IgorC [24]

Answer:

  20 cm by 25 cm by 41 cm

Step-by-step explanation:

You are being asked to solve the cubic ...

  b(2b +1)(b +5) = 20500

I find the easiest way to do that is to use a graphing calculator. By subtracting 20500 to get ...

  b(2b +1)(b +5) -20500 = 0

we can look for a zero of the expression on the left. Many graphing calculators are good at showing those to high precision. Here, we find the only real zero of this equation is at b = 20.

__

Filling in b=20 for the three product dimensions, we find the package size is ...

  20 cm by 41 cm by 25 cm

_____

The rational root theorem tells you that any rational root will be a factor of 20500. This number has 24 divisors. Fortunately there are only 5 that are about 20 or less, so the number of them that need to be tested is minimal. (The cubic has a value greater than 20500 for b > 20.)

You can guess that the solution will be near (slightly less than) ∛(20500/2), since the factors are all near "b" after dividing the second one by 2: (b)(b+1/2)(b+5). That root is about 21.7, so b=20 is a good first guess.
