Answer:
C. 
Step-by-step explanation:
I think the equation meant 
?
Anyways, to factor these kinds of quadratic, keep into consideration:
ONLY if:
Start off by finding factors of c, which in this case, -18:
±(1, 2, 3, 6, 9, 18)
If one of the numbers is negative then the other number must be positive.
Find which two factors will sum up to b, which in this case, is 3.
The only two factors that work are 6 and -3.
Replace them into the factored form:
Answer
Find out the volume of a cylinder .
To prove
Formula
Where r is the radius and h is the height.
As given
Diameter of 12 in. and a height of 7 in.
Radius = 6 in
put all the values in the formula
= 791.28 in³
Therefore the volume of the cylinder is 791 .28 in³ .
Do you need to find what t is? If so, do 300 divided by 60 to get the t isolated. which is, 5.
you can check by doing 60*5 which is 300
Answer:
1/84
Step-by-step explanation:
This was a very complicated problem but the only way that I could solve this was by using a calculator.
Answer:
It is a random sample
The second sample is more representative of a population
The second sample gives better representation because it is larger
Step-by-step explanation:
According to the given statement we have been given two statements and we have to determine how often people in a community listen to the local radio station each month.
If you notice the second sample it is a random sample because people who visited the store had equal probability of being chosen.
The second sample is more representative of a population because it is a larger sample than the first sample and the sample are taken from the only local grocery store.
The second sample gives better representation because it is larger ...
