System of linear equations has been graphed in the diagram. Determine a reasonable solution for the system of equations.
1 answer:
Answer:
D) (0, -3)
Step-by-step explanation:
The solution of two linear equations is the point of intersection of their graphs.
From the graph, the point of intersection of the graphs of the two linear equations is on the y-axis. So, the value on the
axis is always 0. Also, the point is below the x-axis. So, the
value of the point will be negative.
From the choices given, only (0,-3) matches the above conditions.
Therefore, the correct choice is D. (0, -3).

Answer:
Null and alternative hypotheses:
H0: p1 = p2
H1: p1 ≠ p2
To find the sample proportions, we have the following:
Calculate Z statistics:
Z = -2.764
P-value = 0.00285
The pvalue is low.
Since the pvalue is low, reject null hypothesis, H0.

There is strong evidence that patients experiencing the primary outcome is different for those receiving the treatment compared to those without
