Answer: 0.0668
Step-by-step explanation:
Given the following :
Mean (m) Cost = RS385
Standard deviation (s) = RS110
Assume a normal distribution, Probability that domestic airfare is RS550 or more?
P(x > 550)
Find the z - score
Z - score = (x - m) / s
Where x = 550
Z = (550 - 385) / 110
Z = 165 / 110 = 1.5
P(Z > 1.5) = 1 - P(Z ≤1.5)
Using the z table : 1.5 = 0.9332
Therefore,
1 - P(Z ≤1.5) = 1 - 0.9332 = 0.0668
P(x > 550) = 0.0668
Answer:
Step-by-step explanation:
y = 2x - 1
x = 6
y = 3*6 - 1
y = 18 - 1
y = 17
(6,17)
You can eliminate c) because it only had one inequality symbol. Then you subtract 1 from both sides to get x by itself. 6 divided by 3 gives you two. You now have choices A and B. The answer will be B because x represents all values that are less than 2, not just 2 plotted on the number line..
Answer:
12 + -4i
Step-by-step explanation:
14 * (-2i + 6)
-2i (2 + 6i) = -2i * 2 + - 2i * 6i
= -4i - 12i to the power of 2 since (i2 = -1)
= 4i + 12
+12-4i
i's of the form at i6
A=12 and b = -4
