Answer:
Geologists use the following tests to distinguish minerals and the rocks they make: hardness, color, streak, luster, cleavage and chemical reaction. A scratch test developed by a German mineralogist Friedrich Mohs in 1822 is used to determine mineral hardness.
Answer: 1/2
Explanation:
When y is inversely proportional to x. This implies that:
y = k/x
If y = –8 when x = –2, then the constant of proportionality will be;
y = k/x
-8 = k/-2
k = (-8 × -2)
k = 16
when x = 32, the value of y will be:
y = k/x
y = 16/32
y = 1/2
Hey there! :)
Your answer is mean
_____________________________________________________________
Mean is the average value of the data set.
Mode is the number that appears the most
Range is the difference between the greatest value and the lowest value in a data set.
Finding the mode is pretty useless because you can't do much with the score that you got the most.
Range isn't that helpful because it's the difference between your best and worst score.
Mean is best for summarizing because you have 1 number that's the average of the whole data set.

Therefore, the answer is mean
Hope this helps :)
Solution; N:2, H:4, O:3
Step by step solution:
There are 2 n’s
The 4 after the h means that there’s 4 h
And the 3 after the o means that there’s 3 o
