Answer:
∡ZA = 66°
Step-by-step explanation:
Suplementary angles sum 180°
ZA + ZB = 180°
then:
(2x - 14)° + (3x-6)° = 180°
2x + 3x - 14 - 6 = 180
5x - 20 = 180
5x = 180 + 20
5x = 200
x = 200/5
x = 40
then:
∡ZA = (2x - 14)
∡ZA = (2*40 - 14)
∡ZA = (80-14)
∡ZA = 66°
Answer: D
Step-by-step explanation:
Two rays that have a common endpoint
The confidence interval can be calculated from the margin of error, and vice versa,
The margin of error of the confidence interval is 2.156
The confidence interval is given as:
The formula of confidence interval is:
Where E represents the margin of error.
So, by comparison:
Multiply
Hence, the margin of error of the confidence interval is 2.156

464 = 10w + 10u
464 = 10(11.60) + 10u
464 = 116 + 10u
384 = 10u
