Anika [276]

Answer:

d. Ore treated with the new process.

Step-by-step explanation:

This is a common practice in statistics, in which we use a sample of a population to infer something about the entire population. We should use a sample of 100.

For example, if we want to know the proportion of residents of Buffalo, New York, who are Bills fans, we are going to take a sample of like, 100 residents, and then use this to estimate for the entire city.

In this problem, we have that:

A new process that is supposed to increase the recovered amount is being tested. In a simple random sample of 100 batches of ore, an average of 42 pounds per ton were recovered using the new process.

So the population of interest is the ore treated with new process. We use a sample of 100 to gather information about the entire population.

So the correct answer is:

d. Ore treated with the new process.

|-13\ = -(-13)<br> True False?
kolbaska11 [484]

Answer:

This statement is true.

Step-by-step explanation:

The absolute value is how far the number is from zero, so how many steps will it take on a number line to get from that particular number to zero?

Since you can't have negative steps, The -13 in absolute value would be 13.

The -(-13) is the same thing as saying  -1 ( -13 ). Since negative times a negative is a positive, 13=13 is a true statement.
