Answer:
You should <u>carry 2 other batteries.</u>
Step-by-step explanation:
If the average life of each battery tends to last 6.9 months, and what you need is a year of battery supply, you probably need to carry two batteries.
The battery inside the flashlight has probably already spent much of its half-life.
We are told that the flashlight already has a battery inside, the batteries are discharged inside the flashlight even if the flashlight is not being used.
Which means that the average life of that battery is wearing out.
It would take 2 more batteries in addition to the one already inside the flashlight to supply the need for these for a year.
Alright. (1/4^2)+2((1/4)(2/3)-3(2/3^2)=-.9375 is the correct answer

Answer:
The expression 345+791 has a greater value.
Step-by-step explanation:
The first step to figuring out this problem would be to solve the following expressions: 1/2*345=172.5 345+791=1136
The next step to solving the problem would be to compare your answers from your solved expressions: 1136>172.5 OR 172.5<1136
