y=m²-n²
z=m²+n²
Answer:
Third answer
Step-by-step explanation:
1 x 7 = 7
36 x 7 = 252
They are equivalent because 4:5 can both be multiplied by 2 making 8:10.
Get the mixed number into one fraction
Get a common denominator
Now add
You can get it back to a mixed number
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"
