Answer:
Step-by-step explanation:
Here X no of flight that reach on time has two outcomes only and each trial is independent of the other.
Since sample size is large we approximate to normal with mean =np and variance =npq
i.e. X is N(152,19.10)
is used for converting to std normal variate
Continuity correction of 0.5 on either side of interval would be applied for x
a) 
=0.00
b)
=1.00
c) p is N(0.76, sqrtpq/n)=N(0.76,0.0095)
P(p diff>0.03) =
=0.00
Answer
Explanation: To solve this question we will just need to consider some rules as represented below

Step 1: Once we understand both rules above we can use them to simplify our equation as follows

Final answer: So the final answer is

.
Answer:
A = 108 m^2
Step-by-step explanation:
The area of a trapezoid is found by
A = 1/2 (b1+b2)h where b1 and b2 are the lengths of the bases
A = 1/2(10+14) (9)
A = 1/2 (24)*9
A = 108 m^2
Y = -1/3x + 6 . . . (1)
x = -6 . . . (2)
Putting (2) into (1), gives
y = -1/3(-6) + 6 = 2 + 6 = 8
Solution is (-6, 8)
