The probability that the aircraft is overloaded is 0.6141; since this is a greater than 50% chance, the pilot should either reduce the number of passengers on the plane or require them to reduce their baggage.
The z-score for this is given by
z = (X-μ)/σ = (169-180.2)/38 = -11.2/38 = -0.29.
Using a z-table (http://www.z-table.com) we see that the probability of weights being less than this (the area to the left of this score) is 0.3859; to find the probability that the weight is greater than this (to the right), we subtract from 1:
1-0.3859 = 0.6141.
Kieva made 8 cupcakes. 8 * 5 + 8 = 48 desserts.
In order to get this, you just have to try out different numbers of cupcakes and adjust based on whether it's too many desserts total, or not enough.
Another way to figure it out is to say that 1 cupcake + 5 cookies = 6 desserts. Then just divide 48 by 6 to get 8 which will then show you that Kieva made 8 cupcakes.

Answer: 15,22 and 66
Step-by-step explanation: Call the numbers a,b and c.
Their sum is 103 so a+b+c=103
The second number is 7 more than the first so b=a+7
The third number = 3 times the second so c=3b
Now replace c with 3b in the top equation, so a+b+3b=103, which becomes a+4b=103
Now replace b with a+7, so a+4(a+7)=103. This solves to give a=15
b=a+7 so b=22 and c=3b so c=66
