Answer:
1. angle AEB and angle DEF
2.angle AEB and angle CEB
3. angle AEF and angle DEF
4. 120 degrees - vertical angles have the same degree
5. 13 degrees - vertical angle
6. 180-110 = 70 degrees - supplementary
7. 180-65 = 115 degrees - supplementary
Step-by-step explanation:
vertical angle = angles that are opposite of each other where two lines cross
complementary angle = angles that make up the sum of 90 degrees
supplementary angle = 2 angles with the sum of 180 degrees
Answer:
a
Step-by-step explanation:
Answer:
The margin of error M.O.E = 2.5%
Step-by-step explanation:
Given that;
The sample size = 1500
The sample proportion 
= 0.60
Confidencce interval = 0.95
The level of significance ∝ = 1 - C.I
= 1 - 0.95
= 0.05
The critical value:
(From the z tables)
The margin of error is calculated by using the formula:
M.O.E = 0.02479
M.O.E ≅ 0.025
The margin of error M.O.E = 2.5%
Answer:
Step-by-step explanation:
-2,4,-8,16,-32...
Each term is -2 times the previous term.
