Answer:
A
Step-by-step explanation:
You look for groups with the number 1,2,3 in
Answer:
Step-by-step explanation:
angle A = angle B (because they are alternate exterior angles)
8x+6=4x+38
8x-4x=38-6
4x=32
x=32/4
x=8
For angle A
8x+6
8*8+6
64+6
70
For angle B
4x+38
4*8+38
32+38
70
Mean : m = 2.2
Standard deviation: s = 0.3
m - 1 s = 2.2 - 0.3 = 1.9
m + 1 s = 2.2 + 0.3 = 2.5
For the normal distribution the values less than 1 standard deviation away from the mean account for 68.27 % of the set.
Answer: D ) 68 %
