Answer:
The critical <em>z</em>-value for a confidence level of 85% is ±1.439.
Step-by-step explanation:
The critical value of a distribution is the value beyond which the rejection region lies.
For a confidence interval the rejection region lies beyond two values, the positive and the negative critical value.
The confidence level is, 85%.
Compute the critical value of <em>z</em> for 85% confidence level as follows:
*Use a <em>z</em>-table for the value.
Thus, the critical <em>z</em>-value for a confidence level of 85% is ±1.439.
Answer:
(Assuming the circle isn't a zero)
2x + 2y =4
Step-by-step explanation:
For there to be infinite solutions, it should be the same line.
If you divide 2x + 2y = 4 by 2 on both sides you get the original equation
(line A), which is x + y = 2
Can we get a picture please
3/2 x 3/4 is greater than all of them
