(1/2x + 6) • 1
1/2x + 6
Answer:
100°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, thus
∠ACB = 180° - (90 + 50)° = 180° - 140° = 40°
∠ECD = 40° ( vertical angle to ∠ACB )
Since CE ≅ ED then ΔCDE is isosceles and
∠CDE = ∠ECD = 40°
∠E = 180° - (40 + 40)° = 180° - 80° = 100°
I think the correct answer would be option C. The best assumption that will work for a large data set having a normal distribution would be that most of the data points are close to the mean value of the set. Having this assumption, we can use freely the common measures of central tendency as statistical tools.
