Answer:
Step-by-step explanation:
To find tax on something you multiply the base price by the tax percentage. So if something is 100 dollars and tax is 5 percent (or .05 in decimal form), you would add 5 dollars to the price. because 100*.05=5.
If we assume 6% as the tax then we multiply 22.50*.06 = 1.35, so you will add 1.35 to the price. That means the new price is 22.50 + 1.35 = 23.85.
It's just asking for what the tax is though so the answer is 1.35 at 6%. The question does say the tax is over 6% though, so that means the tax will only go up from there if the tax is over 6%
Answer:
-130356
Step-by-step explanation:
solve for bracket first
4-21730 = -21726 then multiply by 6 =
-130356
Answer:
The statistic for this system of hypothesis is given by:
If the statistic is equal to 1 then that means 
and we don't have enough evidence to conclude that the two population variances and deviations are different.
Step-by-step explanation:
System of hypothesis
We want to test if the variation for a group1 is equal to another one 2, so the system of hypothesis are:
H0: 
H1: 
Calculate the statistic
The statistic for this system of hypothesis is given by:
If the statistic is equal to 1 then that means and we don't have enough evidence to conclude that the two population variances and deviations are different.
