Biased or Unbiased:
Take 20 packages off the top of the load of packages being shipped by a truck and measure the amount of damage expected to the whole truckload.
Answer: It is a biased way of taking sample. Because the top layer of packages has less weight resting on it and may have less damage. Therefore, the given statement is biased and based on these 20 packages of the top of the load, we can not make a decision about how much damage a truckload contains.
Step-by-step explanation:
DC+ da+ bc -180
so now you can calculate
Answer:
100
Step-by-step explanation:
You are given the equation

There are 5 coefficients:

Two of them are integers

two of them are decimals with one digit after point

and one is a decimal with two digits after point

To get rid of fractions, we have to get rid of digits after point. The maximum number of digits after point is 2, then we have to multiply the equation by 100:
