Before raw data can be used as scientific evidence, it must be analyzed and summarized. One way of summarizing data is to find t
Sindrei [870]
To calculate the mean, you add up all of the data values, and then divide that sum by the *number* of values.

For instance, if you wanted to find the mean score at a home run derby, and you’re given the following numbers for home runs scored by each player:

5, 4, 6, 5, 3, 1

You could calculate the mean by adding all of the score up

5 + 4 + 6 + 5 + 3 + 1 = 24

And dividing by the number of hitters (in this case, 6)

24 / 6 = 4

So the *mean score* of the home run derby would be 4.

Help! please! hurry! I will mark brainliest if you get it correct!! NO SPAM!!!!!!
Troyanec [42]

Answer: 5.747 * 10^14 Hz

Explanation:

Convert 522nm to m = 522 * 10^-9 m (since 1nm=10^-9m)

If c = wavelength * frequency, where c is the speed of light (3.0 * 10^8 m/s), then you can manipulate the equation to solve for frequency (f).

f = c / wavelength

Plug in the given numbers:

f = (3.0 * 10^8) / (10^-9)

f = 5.747 * 10^14 Hz

Rashid [163]

Answer:

C.Melt both cubes and look for a broader range of melting temperatures. The one that melts over a broader range of temperatures is the amorphous solid.

Explanation:

Amorphous solids is one that do not have a fixed melting points but melt over a wide range of temperature due to the irregular shape hence its name. Contrariwise crystalline solids, have a fixed and sharp melting point.

This comes in handy to solve the riddle. We can characterise the pair with the melting point property.
