Answer:
B, C, F
Step-by-step explanation:
B- has different lengths for each side and different angles
C-has different lengths for each side and different angles
F-has different lengths for each side and different angles
Non congruent triangles means if shape is reflected or rotated they would not look the same. Congruent triangles have same equal length and angles are equal in measure.
X should equal 52. Sorry if I am wrong.
Answer:
Mean = 62
Step-by-step explanation:
X = mean ± sd
82 = mean + 2(s.d) - - (1)
32 = mean - 3sd ___(2)
82 = mean + 2sd
82 - 32= 2sd + 3sd
50 = 5sd
sd = 50/5
sd = 10
From (2):
32 = mean - 3sd
32 = mean - 3(10)
32 = mean - 30
32 + 30 = mean
62 = mean
The answer would be 48. I hope that helped
To find the range you subtract the largest number from the smallest 20-13=7. To find the interquartile range you have to find the median of the data set. The median is 18.5, now there are two sets split in half. The median for the lower quartile is 14.5 and the median for the upper quartile is 19. Range=7 and IQR=18.5-14.5=4. IQR=4
