Answer:

y>2x+1 and x+y < -2 represent the graph line.

Step-by-step explanation:

Given : graph .

To find : Which system of linear inequalities is graphed

Solution : We have given graph with two line both lines are dotted line and shaded down.

Equation of line form  : y = mx + b.

Where, m = slope ,  b= y intercept.

Line x+y < -2 less than sign for shaded down and y intercept -2.

and y>2x+1.

Therefore, y>2x+1 and x+y < -2 represent the graph line.

Both lines are dotted so no equation should include equal to in it.

The shaded area is on the left side .

The correct answer would be y>2x+1 and x+y = -2

The 3rd answer is correct.

Tell whether (-1,2) is a solution of 8x+y&gt;-6
harina [27]

Answer:

Not a solution.

Step-by-step explanation:

(x, y)

(-1, 2)

Substitute the x and y values in the expression with the point given.

8x + y > -6

8(-1) + 2 > -6

-8 + 2 > -6

-6 > -6

Since our final value has to be greater than -6 but is instead equal to -6, the solution is not true.

g In a one-tail hypothesis test where you reject H0 only in the lower tail, what is the p-value if Z STAT
zepelin [54]

Answer:

The P-value is 0.0166.

Step-by-step explanation:

<u>The complete question is:</u> In a​ one-tail hypothesis test where you reject H0 only in the lower ​tail, what is the p-value  if ZSTAT = -2.13.

We are given that the z-statistics value is -2.13 and we have to find the p-value.

Now, the p-value of the test statistics is given by the following condition;

                    P-value = P(Z < -2.13) = 1 - P(Z \leq 2.13)

                                  = 1 - 0.9834 = <u>0.0166</u>

Assuming that the level of significance is 0.10 or 10%.

The decision rule for rejecting the null hypothesis based on p-value is given by;

  • If the P-value of the test statistics is less than the level of significance, then we have sufficient evidence to reject the null hypothesis.
  • If the P-value of the test statistics is more than the level of significance, then we have insufficient evidence to reject the null hypothesis.

Here, the P-value is more than the level of significance as 0.0166 > 0.10, so we have insufficient evidence to reject the null hypothesis, so we fail to reject the null hypothesis.
