Answer:

This is incorrect because a Lunar Eclipse blocks the Sun's rays from reaching EARTH. So for a few seconds, maybe minutes, there is not direct light on earth. So she is incorrect.

Explanation:

I am pretty sure this is right. I hope this helps

1.<br> Draw the Dot Structure for Na!
stepladder [879]

Answer:

Na ·

Explanation:

Hello!

In this case, since the Lewis dot structure of any element illustrates the number of valence electrons at the outer shell; we can set up the electron configuration of sodium to obtain:

Na^1^1\rightarrow 1s^2,2s^2,2p^6,3s^1

We can see there is only one valence electron, for that reason the Lewis dot structure is:

Na ·

Whereas the dot represents the valence electron.

Best regards!

meteorologist preparing a talk about global warming compiled a list of weekly low temperatures (in degrees Fahrenheit) he observ
Setler [38]

Answer:

Regarding Measures of center, the Mean will be smaller, and Median will not be affected. Thus, the median will not change, since the temperature was already low initially and only decreased. However, the median takes the average of all values into account, and if you substitute a value for a smaller value, the average decreases.

In relation to Measures of spread, the range and standard deviation will be larger, and the IQR will not change. Therefore, the range is the highest minus the lowest number; if the lowest number decreases sharply, the range increases. On the other hand, the IQR only counts the first and third quartile values. Therefore, since the value was already the lowest, if it is decreased, it will not change the IQR. However, the standard deviation will increase significantly, as the decreasing value of the lowest data point will increase the overall spread.
