Answer:
0,3% and 0,003
Step-by-step explanation:
To make it as a percent, remeber that you need to transform this fraction to \frac{something}{100}
Therefore, we can divide 1000 by 10, to get the 100.
So we have:
\frac{3}{1000} / 10 = \frac{3 / 10}{1000 / 10} = \frac{0,3}{100}
Note: 3 / 10 is 0,3 (you move the comma to the left as much zeros)
and 1000 / 10 is 100 (you cut the zeros)
As we know have a fraction that is 100 on the denominator, we assume that \frac{0,3}{100} is 0,3%
Now, to get the fraction as decimal, just use the same hint I gave in the other part of the exercise (you move the comma to the left as much zeros).
Therefore, \frac{3}{1000} is 0,003

Answer:
8.284 × 10^4 m^2
Step-by-step explanation:
The area is the product of length and width:
(5.45·10^5 m)·(0.152 m) = 0.8284·10^5 m^2 = 8.284·10^4 m^2
Answer: (A) H0: μ = 140 mg vs. H1: μ ≠ 140 mg
Step-by-step explanation:
Usually null hypothesis represents the claim that the values associated to the groups being tested have no statistical difference but alternative hypothesis supports the claim that there is statistical difference.
Let be the population mean .
We are given that the mean potassium content of a popular sports drink is listed as 140 mg in a 32-oz bottle.
i.e. Null hypothesis :
Alternative hypothesis for two tail hypothesis has sign (≠).
i.e. Alternative hypothesis :
∴ The hypotheses for a two-tailed test of the claimed potassium content:
H0: μ = 140 mg vs. H1: μ ≠ 140 mg
