Step-by-step explanation:
Answer:
(3,1)
Step-by-step explanation:
When reflecting over the y-axis if the point was on quadrant 1, then the coordinated must be changed like so (x,y) -> (-x,y), so therefore in the scenario, all we have to do is reverse this process. So in this case, Point A is (-3,1) so all we have to do is change the -3 to a positive 3 to the the coordinates of A'' which is (3,1).
If i remember correctly 500*3.2%=16 and 16*4 equals $64.
Answer:
Step-by-step explanation:
The hypothesis is written as follows
For the null hypothesis,
µd ≤ 10
For the alternative hypothesis,
µ > 10
This is a right tailed test
Since no population standard deviation is given, the distribution is a student's t.
Since n = 97
Degrees of freedom, df = n - 1 = 97 - 1 = 96
t = (x - µ)/(s/√n)
Where
x = sample mean = 8.9
µ = population mean = 10
s = samples standard deviation = 3.6
t = (8.9 - 10)/(3.6/√97) = - 3
We would determine the p value using the t test calculator. It becomes
p = 0.00172
Since alpha, 0.01 > than the p value, 0.00172, then we would reject the null hypothesis. Therefore, At a 1% level of significance, there is enough evidence that the data do not support the vendor’s claim.
