Order least to greatest, 0.3, 19 over 40 ot 22%

22%, 0.3,

Step-by-step explanation:

To make this more simple to figure out, let's change everything into a percentage.

To change 0.3 to a percentage, simply move the decimal point right two spaces. Now you have 30%.

Now to change to a percentage. Simply divide 19 by 40.

19 ÷ 40 = 0.475

Now we do what we did above; change the decimal to a percentage.

The decimal is now 47.5%.

22% is already a percentage.

Now, let's compare.

30%, 47.5%, 22%

The greatest number seems to be 47.5%, while the least is 22%.

Let's organize it from least to greatest.

22%, 30%, 47.5%

Now, change the percentages back to their original numbers.

47.5% =

30% = 0.3

22% = 22%

22%, 0.3,

correct answer:

i^31 = -i

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
