Both Maria and Edwin are correct
Maria's method
25% of 26.50 = 6.625
26.50 - 6.625 = 19.875
10% of 19.875 = 1.9875
19.875 + 1.9875 = 21.8625 as final price
Edwin's method
75% of 26.50 = 19.875
110% of 19.875 = 21.8625 as final price
The book is 25% off the original price, so the remaining value is 75% of the original value
By adding 10% tax on to the original price, the final price will be 100%+10%=110% of the original price
Both Edwin and Maria has enough money to purchase the book
Answer:
Step-by-step explanation:
To find the slope between these two points, we can use the slope formula.
-3 + 7 / -4 - 1
4 / -5
-4/5
The slope of the line between these two points is -4/5. (This is your answer.)
Answer:
with 0.10 level of significance the P-VALUE that would be used in the hypothesis claim is 0.05%
Step-by-step explanation:
In hypothesis testing in statistics, we can say that the p-value is a probability of obtaining test results when we assume that the null hypothesis is correct.
The p-value is the probability that the null hypothesis is true.
A p-value less than or equals to 0.05 is statistically significant. It shows strong evidence against the null hypothesis, meaning there is less than a 5% probability the null is correct and clearly we can say that the results are random.
