Answer:
A=132
Step-by-step explanation:
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=3·10+4·10+5·10+1
2·﹣34+2·(3·4)2+2·(3·5)2﹣44+2·(4·5)2﹣54=132
Answer:
A) No
B) No
C) Yes
Step-by-step explanation:
A) 2 out of three observations is equal to
2/3 = 0.67 or 67 %
We know tha the interval
[μ - σ/2 , μ + σ/2] is approximately 68.3 % of the values
Therefore 2 out of 3 would not fall in that interval
B)
4 out of 5 is 4/5 = 0,8 or 80 % If we examine the interval
[μ - σ , μ + σ ] which is approximately 95. Then value 4/5 ( 0,8)
Therefore 0,8 is out of the interval
C) 19/20 = 0,95 or 95 % is almost exact the value for the interval
[μ - 1.5σ , μ + 1.5σ ] That value is inside μ - 2σ , μ + 2
Answer:
12 teams
Step-by-step explanation:
We know that 38 players can fit into 4 groups, 8 times ...
32 divide 8 = 4
We have the number with 96, and we need to find the groups
we do the same as done with the first one...
because 32 divided by 8 is 4
we do
96 divide 8 = 12
