Answer:

no solution

Step-by-step explanation:

The equations describe parallel lines. There are no values of x and y that will satisfy both equations.

In standard form, the two equations are ...

3x +7y = 21

3x +7y = -42 . . . . . with positive leading coefficient

If (x, y) values satisfy the first equation, they cannot satisfy the second equation, and vice versa.

Answer:

0.5375

Step-by-step explanation:

The point estimate of proportion of all Americans who are in favor of outlawing cheese can be computed as

p=x/n

Here. x is the number of favorable outcomes and n is sample size.

We are given that x=2150 and n=4000, So,

p=2150/4000

p=0.5375.

Thus, the point estimate of proportion of all Americans who are in favor of outlawing cheese is 0.5375.
