Since it's on sale and her aunt can discount it, the total discount is 40% off. Take 100 and subtract it from 40. You'll get 60. Since 40% is equal to .40, make 60 a decimal as well. .60. Take .60 and multiply it by 160. You'll get 96. Now for the tax.
Take 7.5 and ADD it to 100, giving you 107.5. Move the decimal over twice making it 1.075. Take 1.075 and multiply it by the 96 we got earlier. That gives you $103.20
The answer is $103.20
Answer:
The conditions for carrying out a significance test are:
1. It must be a Random sampling
2. It should be a Normal distribution
3. It should be Independent
Step-by-step explanation:
SRS means simple random sample; it is a sampling technique in which individuals can be chosen from the population in such a way that every individual stands an equal chance to be selected as the sample.
The conditions needed or required to carry out a significance test of the teacher's suspicion are:
1. It must be a Random sampling
2. It should be a Normal distribution
3. It should be Independent
All of these conditions are met; the sampling is random as indicated by SRS, it is a normal distribution because one popular rule states that a sample size of at least 30 is enough and here we have a sample size of 45, it is independent because the sample size of 45 is less than 10% of the population
2617.0 would be the answer
