Using statistical concepts, it is found that the term that best describes the number 92% is:
a. statistic.
- If the information is taken from a sample, it is called a statistic.
- If the information is taken from a population, it is called a parameter.
In this problem, 92% of those polled said that a year from now their family financial situation will be as good as it is today or better, that is, 92% of the sample, hence, it is a statistic, and option a is correct.

The true statement about the Internet connection cost is D. Any amount of time over an hour and a half would cost $10.
<h3>How to explain the cost?</h3>
In this situation, the function is f (t), when t is a value between 0 and 30. The cost is $0 for the first 30 minutes
When t is a value between 30 and 90, the cost is US$ 5 if the connection takes between 30 and 90 minutes.
Here, the true statement about the Internet connection cost is D. Any amount of time over an hour and a half would cost $10.

Answer:
After solve the equations we get value of k=3
Step-by-step explanation:
We need to find value of k for which the lines x+2y=0, 3x-4y-10=0 and 5x+ky-7=0 are concurrent.
If the lines are concurrent, they pass through same point.
Let:
First solving equation 1 and 2 to find values of x and y
From eq(1) we find value of x and put it in eq(2)
After solving we get value of y=-1
Now putting in eq(1) to get value of x
So, Value of x= 2
Now put value of x=2 and y=-1 into eq(3) to find value of k
So, After solve the equations we get value of k=3
