Answer:
The claim that he rate of inaccurate orders is equal to 10% is supported by statistical evidnece at 5% level
Step-by-step explanation:
Given that in a study of the accuracy of fast food drive-through orders, one restaurant had 34 orders that were not accurate among 371 orders observed.
Sample proportion
(Two tailed test at 5% significance level)
p difference =
Std error if H0 is true =
Test statistic Z = p diff/std error
=0.539
p value = 0.5899
Since p > 0.05 accept null hypothesis
The claim that he rate of inaccurate orders is equal to 10% is supported by statistical evidnece at 5% level
The formula for a vertex form equation is
in which (h,k) represents the vertex
Your equation is in vertex form, if you mpve the -7 to the other side you will get
because you have to add 7 to both sides
based on the equation,
h=10
k=7
(h,k)=(10,7)
your vertex is (10,7)
