Answer:
190
Step-by-step explanation:
20 percent is 1 fifth of 100 percent so 38 would be 1 fifth. so multiply by 5
the question says that the samples included 100 people each, so it's just 100 multiplied by the amount of samples:
7×100=700
Answer:
1.008

Any line can be expressed in the form y=mx+b where m is the slope and b is y intercept.
Two lines can either be parallel ,overlap or meet at one point .Let us look at different cases :
1)When two lines are parallel they do not intersect at any point and hence the system of equations have no solution.
2) When two lines overlap each other then the two lines touch each other at infinite number of points and we say the system of equations have infinite solutions.
3) When two lines intersect each other at one point we say the system of equation has one solution.
Part A:
The given lines are intersecting at one point so we have one solution.
Part B:
The point of intersection is the solution to the system of equations .In the graph the point of intersection of the lines is (4,4)
Solution is (4,4)
