Answer:
False
Step-by-step explanation:
Answer:
The answer to your question is the third choice.
Step-by-step explanation:
a) 6x - 5y = 8
12x - 10y = 16
We observe that these lines are the same so they have infinite solutions.
b)
7x + 2y = 6
14x + 4y = 16
These lines are parallel because they have the same slope, so they do not cross, there is no solution.
c)
8x - 3y = 10
16x - 6y = 22
These lines are parallel because they have the same slope, so they do not cross, there is no solution.
d)
9x + 6y = 14
18x + 12y = 26
These lines are parallel because they have the same slope, so they do not cross, they do not have an infinite number of solutions.
Standard form of linear equations in two variables is ax+by+c=0
Here,
3x-y-1/5=0
Answer: 50
Step-by-step explanation: 100 / 2 is 50
Answer: 126
Step-by-step explanation:
As per given , we have
Prior Population proportion : 
Significance level : 
Critical value for 95% confidence interval (using the z-value table) = 
Margin of error (maximum error): 
Formula to find the sample size :

Therefore , the required minimum sample size = 126
