Okay, so let's find the actual failure rate first. 6/1000 times 100 (to give over a 100%) equals to 0.6. The actual failure rate is 0.6%. The theoretical probability is 0.2% 0.6-0.2=0.4. The difference is 0.4%.
Hope that helped!
Answer:
4 - pound bag of pears for $14.08
Step-by-step explanation:
To find out which is the better deal, we have to simplify it.
By dividing $14.08 by 4, this gives us the amount of $ each pound costs, which is $3.52.
Now let's find out the amount of $ each pound costs for the 94- ounce bag of pears for $22.56.
First, we need to convert from ounces (oz) to pounds (lbs).
There are 16 ounces in one pound, and we have 94 ounces. So, 94/16 = 5.875 pounds. So there are 5.875 lbs in the $22.56 bag. Now we need to find the amount of $ each pound costs. So we divide $22.56 by 5.875 and we get $3.84.
$3.52 < $3.84 (this is the amount of money each pound of pears cost for each bag). The first bag is cheaper per pound, so they should buy the first one (which is the 4 pound bag btw).
