-4(x-4)=-44<br> Please answer this with how you got the answer.

devlian [24]

Answer: x = -15

Step-by-step explanation:

Think PEMDAS

First, we factor the parenthesis:

-4 (x-4) = -4(x) + -4(-4)

now we are left with -4x + 16 = -44

Next is to isolate the "x":

to do this, we must subtract 16 from -44

-44 - 16 = 60

now we have -4x = 60

Now we divide both sides by -4 in order to isolate "x"

dividing -4x/-4 = x

diving 60/-4 = -15

the answer is x= -15

The lengths of lumber a machine cuts are normally distributed with a mean of 100 inches and a standard deviation of 0.3 inch. (

ki77a [65]

Answer:

a) 0.345

b) 0.005

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 100

Standard Deviation, σ = 0.3

We are given that the distribution of lengths of lumber is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

a) P(length greater than 100.12 inches)

P(x > 100.12)

$P( x > 100.12) = P( z > \displaystyle\frac{100.12 - 100}{0.3}) = P(z > 0.4)$

$= 1 - P(z \leq 0.4)$

Calculation the value from standard normal z table, we have,

$P(x > 100.12) = 1 - 0.655 = 0.345 = 34.5\%$

b) Standard error due to sampling:

$\displaystyle\frac{\sigma}{\sqrt{n}} = \frac{0.3}{\sqrt{41}} = 0.0468$

P(length greater than 100.12 inches for the sample)

P(x > 100.12)

$P( x > 100.12) = P( z > \displaystyle\frac{100.12 - 100}{0.0468}) = P(z > 2.564)$

$= 1 - P(z \leq 2.564)$

Calculation the value from standard normal z table, we have,

$P(x > 100.12) = 1 - 0.995 = 0.005$
