For the first three questions
5/12 = 35/N
Rearrange: N = 35 / (5/12) = ( 35 / 0.4167 ) = N = 83.99
7/18 = N / 9
Rearrange: N = (7/18)* 9 = 3.5
(2/5) * 240 = 96
He spent $96 on supplies
Answer: The required lifetime value is 11.27.
Step-by-step explanation:
Since we have given that
Mean value = 11 hours
Standard deviation = 1 hour
The total lifetime of all batteries in a package exceeds that value for only 5% of all packages.
So, α = 0.95, z= 1.645
n = 9
So, the lifetime value would be
Hence, the required lifetime value is 11.27.

Hope I explain myself :/
Try to find ways that you can easily remember formulas. For example, when you find the line of symmetry the equation is y=-b/2a. A way you can remember that is by saying negative tuba. It seems silly but it’s something you can do for most equations so it doesn’t seem so intimidating.
