Plug the coordinates into the distance formula and solve.
Answer:
a. hourly rate
b. the cost before the tax
c. tax rate
d. tax amount
e. 299.6
Step-by-step explanation:
When you look at the formula, since h represents the number of hours and it is multiplied with 80, you can tell that 80 is the hourly rate. This is how you would calculate the cost if there was no tax. Also, you can see that it is also multiplied with 0.07, that implies 0.07 is the tax rate and 0.07(80h) is the tax amount.
Since h represents the number of hours in the given formula:
→ 0.07(80h)+80h = 0.07(80(3.5)) + 80(3.5) = 19.6 + 280 = 299.6
Answer:
Step-by-step explanation:
adjacent angles share a ray
they also have a common vertex
Answer:
Option B - There is at least some difference in the average times spent by the two groups in the mall.
Step-by-step explanation:
A null hypothesis is a hypothesis that states that there is no statistical significance between the two variables. Thus, It is usually the hypothesis that a researcher or experimenter will try to disprove or discredit. While an alternative hypothesis is one that states there is a statistically significant relationship between two variables.
Now, applying these definitions to the question, we can see that;
Null Hypothesis is;
H0; There is no difference in the average times spent by the two groups in the mall
While the alternative hypothesis is;
Ha; There is at least some difference in the average times spent by the two groups in the mall
Thus, correct answer is option B
