Answer:
D. 0.002
Step-by-step explanation:
Given;
total number of sample, N = 500 elements
50 elements are to be drawn from this sample.
The probability of the first selection, out of the 50 elements to be drawn will be = 1 / total number of sample
The probability of the first selection = 1 / 500
The probability of the first selection = 0.002
Therefore, on the first selection, the probability of an element being selected is 0.002
The correct option is "D. 0.002"
1/4 as when you divide them both as a fraction that’s what you would get based on this data as it is very limited
There are like terms in this problem. It looks scary but if we combine our like terms it makes it a lot easier. Also, like terms are terms with the same variables that are at the same power.
So add 7a^2 and -3a^2
You'll get the following sum:
4a^2
Add -17a and 2a
You'll get the following sum:
-15a
So our new problem looks like this:
4a^2 - 15a = 0
Factor out the variable "a." Leaving you with this:
We can rewrite the problem like this:
4a^2 - 15a + 0 = 0
Now we can use the quadratic equation!
Where +/- is simply the add or divide symbol. Now let's plug in our numbers!
Simplifying a bit you get the following function:
sqrt(225) = 15
15 + 15 = 30
30 / 8 = 15/4
15 - 15 = 0
0 / 8 = 0
Your two answers are:
15/4 and 0
