Answer:
0.2061
Step-by-step explanation:
Probability (no crash) = 66% = 0.66
Average (no crash) expected out of 152 computers = 0.66 (152) = 100.32
Standard deviation 's' = √ [ (154) (0.66) (1-0.66) ] = √ (154) (0.66) (0.34)
= √ 34.5576 = 5.87
P (x <u>></u> 96) = 1 - P (x <u><</u> 95)
z= (x - u) / s ; x = sample mean = 95.5 (continuity correction factor = 0.5) , u = population average = 100.32
z = (95.5 - 100.32) / 5.87 = 4.82 / 5.87 = 0.82
P (x <u><</u> 95) = P (z <u><</u> 0.82) = 0.7939
P (x <u>></u> 96) = 1 - 0.7939 = 0.2061

Answer:
2.084...
Step-by-step explanation:
Just write an non repeating string of any numbers that you think of but not in a pattern which will lie between decimal value of your 2 numbers
To Germany: We do the total of trips to Germany, 8, divided by the total number of trips, 40, or 1 over 5.
To France or Spain: We add the totals of France and Spain to get 32, and divide this by the total, 40, to get 4 over 5.
To France by plane: We look only at the number of trips to France by plane specifically and see 3, then put this over the total, 40, to get the simplest form as 3 over 40.
To Spain by plane: We do the same process as France by plane, but with 6 trips, so the answer is 6 over 40, which simplifies to 3 over 20.
Hope this helps.
It would be a right angle because all the angles are less than 90 degrees
