Answer:
Step-by-step explanation:
Given that a seller has acquired 120 randomly selected items from a vendor for his stores. He has an allowance of 10% for damaged items. Of the 120 items acquired from the vendor, the seller found that 15 are damaged.
Population proportion= 0.10
Sample proportion = 15/120 = 0.125
To test whether the population proportion of the vendor's items exceeds the seller's allowable limit,
the hypotheses would be
(right tailed test)
Answer:
Step-by-step explanation:
From the graph in the attachment Y has coordinates:Y(3,2)
The transformation rule for a dilation with a scale factor k about the origin is:
In this case we have
We substitute the coordinates and to get:
This simplifies to:
The first choice is correct.
ok you need formula for surface area.
SA = πrh+2πr^2
Plug in 25 and 5
SA = 2π(5)(25)+2π(5)^2
SA = 10pi*25 + 2pi(25)
SA = 250pi + 50pi
SA = 300pi
Hope this helps :)
