Answer:2.26796
Step-by-step explanation:
The first thing to note is since one gallon= 60 miles then 1/2 gallon= 30 miles, now I know 1/2 is not an answer but it is easiest to decrease in moderate amounts. 1/2 gallon= 48 Km so we are close, and 1/2=0.5 so if we brought it down to 0.42 we would have 25.2 miles and 25.2 miles = 40.32. The question wants to know the approximate number and 40.32 is the closest we are going to get so the answer is 0.42
The force of gravity is when the distance between two objects is d is:
F=(G*m1*m2)/d^2
Answer:
(3, -3)
Step-by-step explanation:
When asked to solve by elimination, you put them on top of one another, like you're going to add it.
10x + 7y = 9
-4x - 7y = 9
See that 7y? You can cancel those out because one is negative, and one is positive. So those are gone. You finish adding the rest of the numbers as usual and solve for x.
6x = 18
x = 3
Take x, and plug it into either equation to find y.
10(3) + 7y = 9
7y = -21
y = -3
(3, -3)
Hope this helped!
Answer:
The correct option is (C) convenience sample.
Step-by-step explanation:
Convenience sampling is a kind of non-probability sampling, i.e. all items does not have an equivalent chance or probability of being selected. This type of sampling method does not comprises of random collection of items.
Convenience sampling is where we take in items which are easy to reach or collect.
For example, sampling the the students of your own class or collecting sample from your own neighborhood.
In this case the Chief Financial Officer of Harrison Haulers, Inc. asks her staff to inspect the last 200 vouchers of the 2500 payroll vouchers that have been issued since January 1, 2000.
She did so because her staff did not have that much time in hand and it is quite convenient to check the last 200 vouchers.
This is because it is quite easy to review the last 200 payroll vouchers since they would be the most recent ones and quite easily accessible.
So, the sampling method used by the Chief Financial Officer of Harrison Haulers, Inc. is Convenience sampling.
Thus, the correct option is (C).
