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.
X = 16
x = - 16
You could do it this way
x^2 - 256 = 0
(x - 16)(x + 16) = 0
x - 16 = 0
x = 16
x + 16 = 0
x = - 16
Answer:
-3x²+17x-20
Step-by-step explanation:
When you apply the distributive property (which you did correctly), you simply multiply each number or variable in which you have to distribute it to (which again you wrote correctly) and then you add them all together.
(3x)(-x)=-3x²
+
(3x)(4)=12x
+
(-5)(-x)=5x
+
(-5)(4)=-20
Add those and you will get your answer. Hope this helped :)
Answer:
1 2/3
Step-by-step explanation:
Change the mixed number to an improper fraction
5 5/6 = (6*5+5)/6 = 35/6
Multiply the improper fraction by the fraction
5 5/6 * 2/7
35/6 * 2/7
70/42
Divide the top and bottom by 14
5/3
Changing back to a mixed number
3/3 +2/3
1 2/3
A = about 295.86 if you the diameter then you know what the radiaus is. the formula is A=πr(r+h^2+r^2<span>)</span>
