(2/7)m - (1/7) = 3/14
2m/7 =(3/14) + (1/7)
2m/7 = (3/14) + 2(1/7)
here we are multiplying 2 with 1/7 to make the denominator same for addition.
2m/7 = (3/14) +(2/14)
2m/7 = (3 + 2)/14
2m/7 = 5/14
2m = (5 *7)/14
2m = 35/14
2m = 5/2
m = 5/4
m = 1.25
So the value of "m" is 1.25
Ansswer:
I think that options include:
A. With a high level of confidence, the republican defeated the democrats
B. the republican definitely defeated the democrats
C. the republican defeated the democrats with probability of 0.60
D. It is not possible to predict the winner because less than 1% of the voters were in the sample
Answer: Option D
Step-by-step explanation:
The result of this election cannot be predicted accurately as only 1000 voters out of 3,000,000 were sampled.
To get a good sample, the sample must be at least 10% of the total population and be a representative of the population but in this context, the sample is even less than 1% (30,000). Thus, the prediction might be inaccurate...

Hi friend,
The objective is to divide $20 in 2:3 ratio.
One part be 2x, another part is 3x
Sum of them = 20
2x + 3x = 20
5x = 20
x=4
So therefore one part must be 2x = 2 x 4 = 8
Another part = 3x = 3 x 4 = 12
Hence it is divided in 2:3 ratio.
Hope my answer is helpful to u. :)
