Answer:
100/100
Step-by-step explanation:
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
1/ we make -3*and and we have y=-1 and we replaced to have x=6
2/ any answer x=(7y+3)÷2
If we change answer of x in the second equation we get -7y-3+7y=-3
3/ x=-4+2y we change it in the second equation and we get y =1 if replace it in the first we have x=-2
4/ B=10 and C=16
5/ a= false
b=true
c=true
d=true
I think it would be 5,081 X 10 to the 6th power
