Answer:

$97.70

Step-by-step explanation:

So to find percent

450/100= 4.5 ,4.5x15= 67.5

82/100=0.82 0.82x15= 12.2

120/100=1.2   1.2x15=18

So do 67.5+12.2+18=  $97.70

Since a straight line is 180 degrees, if you subtract 180-48 you get 132. Divide this by 2 and get X= 66. Because all angle of a triangle add up to 180, subtract the 90 from the right angle and 66 from x from 180. 180-66-90= 24. This means z=24

A machine is designed to fill 16-ounce bottles of shampoo. When the machine is working properly, the amount poured into the bott
Andreyy89

Answer:

(15.8495,16.2505)  

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 16.05 ounces

Standard Deviation, σ = 0.2005 ounces

We are given that the distribution of amount poured into the bottles is a bell shaped distribution that is a normal distribution.

Empirical rule:

  • It states that for a normal distribution, almost all data falls within three standard deviations (denoted by σ) of the mean (denoted by µ).
  1. It shows that 68% falls within the first standard deviation (µ ± σ), 95% within the first two standard deviations (µ ± 2σ), and 99.7% within the first three standard deviations (µ ± 3σ).

Confidence interval:

\mu \pm 2\frac{\sigma}{\sqrt{n}}

Putting the values, we get,

16.05 \pm 2(\frac{0.2005}{\sqrt{4}} ) = 16.05 \pm 0.2005 = (15.8495,16.2505)
