Answer:
(2,3)
Step-by-step explanation:
To find the x-coordinate of the midpoint, find the average of -6 and 10. It is 4/2, or 2.
To find the y-coordinate, proceed similarly. Find the average of 2 and 4. It is 3.
Thus, the midpoint is (2, 3).

We are asked to solve for: "6t" ; which is: "6 * t" .
__________________________________________
Given: 3t − 7 = 5t ; Solve for "t" ; then solve for "6t" ;
3t − 7 = 5t ; Subtract "3t" from each side of the equation;
____________________________________________
3t − 7 − 3t = 5t − 3t ;
to get: -7 = 2t ;
Divide EACH side of the equation by "2" ; to isolate "t" on one side of the equation; and to solve for "t" ;
-7/2 = 2t / 2 ;
-3.5 = t ; ↔ t = - 3.5 ;
____________________________________________
Now, solve for "6t" ;
6 t = 6*(-3.5) = - 21 . The answer is: " -21 " .

Answer:
Step-by-step explanation:
The margin of error is computed using the formula:
The critical of <em>z</em> for 95% confidence level and 90% confidence level are:
*Use a <em>z</em>-table.
The sample size is n = 44.
Compare the MOE for 95% confidence level and 90% confidence level as follows:
