Answer:

$11\frac{170}{333}$

Step-by-step explanation:

let x=11.510510510...

multiply by 1000

1000x=11510.510510...

again multiply by 1000

1000,000 x=11510510.510510...

subtract

999,000 x=1,1 49 9,000

x=11,499,000/999000=3,833,000/333,000=3833/333

333 ) 3833 (11

The weights of certain machine components are normally distributed with a mean of 5.19 ounces and a standard deviation of 0.05 o

Brums [2.3K]

Answer:

The weight that separate the top 8% by 5.2605 and the weight that separate bottom 8% by 5.1195.

Step-by-step explanation:

We are given that

Mean, $\mu=5.19$

Standard deviation, $\sigma=0.05$

We have to find the two weights that separate the top 8% and the bottom 8%.

Let x1 and x2 the two weights that separate the top 8% and the bottom 8%.

Z-value for p-value =0.08 = $-1.41$

For 8% bottom

$Z=\frac{x_1-\mu}{\sigma}=-1.41$

$\frac{x_1-5.19}{0.05}=-1.41$

$x_1-5.19=-1.41\times 0.05$

$x_1=-1.41\times 0.05+5.19$

$x_1=5.1195$

For 8% top

p-Value=1-0.08=0.92

Z- value=1.41

Now,

$\frac{x_2-5.19}{0.05}=1.41$

$x_2-5.19=1.41\times 0.05$

$x_2=1.41\times 0.05+5.19$

$x_2=5.2605$

(x1,x2)=(5.1195,5.2605)
