Answer:
(x-y)(x-y)(x-y)(x-y)
Step-by-step explanation:
(x-y)^4 means multiply (x-y) four times
The original price will be larger than the final price because you would be taxing the discounted price not the original price.
Yes. If you add the sales tax first then the discount wont be on just the product. it would be on the product and the tax with the product. so you have to first get the discounted price from the store and then tax for the county.
Considering that we have the standard deviation for the sample, the t-distribution will be used, and the critical value is t = 2.6682.
<h3>When should the t-distribution and the z-distribution be used?</h3>
- If we have the standard deviation for the sample, the t-distribution should be used.
- If we have the standard deviation for the population, the z-distribution should be used.
In this problem, σ is not known, hence we get the standard deviation of the sample from the histogram and the t-distribution is used.
Using a t-distribution calculator, considering a <em>confidence level of 99%</em> and 56 - 1 = <em>55 df</em>, the critical value is t = 2.6682.

Answer:
The value of X<em> </em>is 6.
Step-by-step explanation:
5 + 3 + 7 + 9 = 24
30 - 24 = 6
