9 watches cost 172,800 (9×19200=172800)
Step-by-step explanation:
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.
Answer:
A. t > 2.5
Step-by-step explanation:
If she wants to achieve <em>more </em>than 590, we already know the sign would be greater than (>).
All we have to do is divide 590/236, which gives us 2.5.
Therefore, she will have to ride more than 2.5 hours to reach her goal, t > 2.5
Hope this helps :)
Good luck on your test.
Answer:
The man has 6 GHc20.00 notes and 4 GHc10.00 left
Step-by-step explanation:
Given
Amount = 3 GH¢50.00, 7 GH¢20.00 and 5 GH¢10.00
Spendings = GH¢80,00
Required
Determine how many GH¢20.00 and GH¢10.00 notes left
The amount he has can be represented as:
This can be represented as:
Represent:
GHc50.00 with x, GHc20.00 with y and GHc10.00 with z
So, we have:
Subtract the spendings from the total to get amount left
Collect Like Terms
Recall that, we have represented:
GHc50.00 with x, GHc20.00 with y and GHc10.00 with z
<em>This means that, the man has 6 GHc20.00 notes and 4 GHc10.00 left</em>
4 + 3s – 9s = 22
4 - 6s = 22
-6s = 18
-6s/-6 = 18/-6
s = -3
S would equal -3
