You have 10 batteries 3/10 are dead there are only 7/10 batteries that are good. So the expected number of good batteries you could get is 7.
The horizontal sums of the survey numbers are 200, so the numbers in the left chart are the survey values divided by 200.
The vertical sum in the first column is 188, so the first column of the right chart will be 76/188 and 112/188. Likewise, the vertical sum in the second column is 212, so the numbers will be 124/212 and 88/212.
Once you find the first number in each case, the second number is that value subtracted from 1, since the total of the two must be 1.
Answer:
at the most 308 pounds
Step-by-step explanation:
Given
Weight of each sack = 364 pounds
Weight of Kevin = w = 150 pounds
Weight that lift can take = 2000 pounds
In order to find the weight of sacks that can be put into the elevator we have to subtract the weight of Kevin from the capacity of the lift.
So, actual weight of sacks that can be taken =
= 1850 pounds
As 6 sacks have to be taken, to find the weight of one sack
Required weight of one sack =
= 308.33 pounds
So, each sack has to weigh at the most 308 pounds ..
