Answer:
x = 125
Step-by-step explanation:
Ok so we already established that AIA are congruent. So two angles will equal 55 degrees. All angles in a parallelogram add up to 360 degrees, and there are two pairs of matching angles opposite of each other.
So we take the two 55 degree angles and subtract them from 360:
360-110 = 250
Now there are two identical angles left, one of them is x, that equal a total of 250, so divide by two:
250/2
=125 degrees
Answer:
Step-by-step explanation:
130 + 125 + 191 = 446, so choice (C)
Hope that helps!

Answer:
D- convenience sampling, the sample would be biased against adults who work during the day
Step-by-step explanation:
Answer:
0.1369
(4.732, 5.268)
Step-by-step explanation:
Given that:
Mean, m = 5
Standard deviation, s = 1.5
Error margin, E = 0.5
Sample size, n = 120
Zcritical at 95% = 1.96
Standard Error of the mean (S. E) :
S. E = s /sqrt(n)
S. E = 1.5 / sqrt(120
S.E = 1.5 / 10.954451
S. E = 0.1369306
S. E = 0.1369
Confidence interval (C. I)
Mean ± (Zcritical * S.E)
5 ± (1.96 * 0.1369)
Lower boundary = 5 - 0.268324 = 4.731676
Upper boundary = 5 + 0.268324 = 5.268324
(4.732, 5.268)
