8 x (5 x 2 + 3)=104 because 5 x 2 is 10, 10 + 3 is 13, and 13 x 8 is 104.
The distance would be 9.
Hope I could help.
angle B& C = 180
C & D = 180
A & D = 180
A & B = 180
A & C are identical so angle x = 63
angle Z = mirrored angle which is 72
180-63 = 117-72 = 45
so angle y = 45
Answer:
a) 21
b) 21
Step-by-step explanation:
Given 10 scores: 19, 15, 34, 29, 13, 35, 10, 19, 14, 22
a) Mean
= (sum of scores) / number of scores
= (19+15+ 34+ 29+ 13+ 35+ 10+ 19+ 14+ 22) / 10
= 210 / 10
= 21
b) one more score of 21 is added
hence
number of scores = 10 + 1 = 11
sum of scores = 210 + 21 = 231
Mean = (sum of scores) / number of scores
= 231 / 11
= 21
See the attached picture.
Answer could change slightly depending on how all the steps are rounded.
