Disregard the sign. Find the mean (add the numbers, and divide by the amount of numbers there are)
2 + 12 = 14/2 = 7
Add 7 (if you are going by -2), if you are starting from 12, subtract 7
-2 + 7 = 5
5 is your midpoint.
hope this helps
The equation is: (Note: Let the two numbers be x and y)
(x + y)/2 = midpoint

Answer: option c
Step-by-step explanation:
margin of error = critical value × s/√n
Where s = sample standard deviation = 0.58, n = 53
The critical value = 1.96 ( this is the critical value for a two test test corresponding to a level of significance of 5%)
By substituting the parameters, we have that
Margin of error = 1.96×0.58/√53
Margin of error = 1.96 × 0.0796
Margin of error = 0.156 ~ 0.16
Answer:
2
Step-by-step explanation:
3+4+(-5)=7+(-5)=7-5=2
Well first the formula for finding exterior angles is (n-2)180
n is the number of angles, so if u have fifteen sides you do (15-2)180
13 x 180 = 2340
Step-by-step explanation:
Area = 0.5(19+25)(20) = 440cm².
