The weights of certain machine components are normally distributed with a mean of 8.04 g and a standard deviation of 0.08 g. Fin
NISA [10]

Answer:

The bottom 3 is separated by weight 7.8896 g and the top 3 is separated by weight 8.1904 g.

Step-by-step explanation:

We are given that

Mean, \mu=8.04 g

Standard deviation, \sigma=0.08g

We have to find the two weights that separate the top 3% and the bottom 3%.

Let x be the weight of  machine components

P(Xx_2)=0.03

P(X

=0.03

From z- table we get

P(Z1.88)=0.03

Therefore, we get

\frac{x_1-8.04}{0.08}=-1.88

x_1-8.04=-1.88\times 0.08

x_1=-1.88\times 0.08+8.04

x_1=7.8896

\frac{x_2-8.04}{0.08}=1.88

x_2=1.88\times 0.08+8.04

x_2=8.1904

Hence, the bottom 3 is separated by weight 7.8896 g and the top 3 is separated by weight 8.1904 g.

Explain how the Quotient of Powers was used to simplify this expression.
Ksju [112]
For this case we have the following expression:
 \frac{5^4}{25}
 Rewriting the expression we have:
 \frac{5^4}{5^2}
 In the division, if we have the same base, the exponents are subtracted.
 Therefore, by rewriting the expression we have:
 \frac{5^4}{5^2}=5^{4-2}
 5^{4-2} = 5^2

 Answer:
 
The equivalent expression is given by:
 
\frac{5^4}{25}=5^2

-5c+5=-40 or - 5c+5=40

-5c=-40-5. - 5c=40-5

-5c=-45. - 5c=35

C=9. C=-7
