Answer 5 1/4
Step-by-step explanation:
simplify --- 2 5/8 = 21/8
flip 1/2 = 2/1
multiply 21/8 x 1/2
answer = 5 1/4
Answer:
EF = 8.8 cm
Step-by-step explanation:
In the given right angled ΔDEF, DE is the hypotenuse while EF and DF are adjacent sides. So that applying the Pythagoras theorem, we have;
=
+ 
=
+ 
=
+ 
262.44 =
+ 184.96
= 262.44 - 184.96
= 77.48
EF = 
= 8.8023
EF = 8.8 cm
The length of side EF is 8.8 cm.
Answer:
All values are identical.
Step-by-step explanation:
We are given the following in the question:
If the standard deviation of a set of data is zero.
Then, all the values in data are identical.
This can be shown as:
Let all the terms in data be x.
Formula:
where
are data points,
is the mean and n is the number of observations.
Sum of squares of differences =


Thus, the correct answer is
All values are identical.
Smaller particles moved by the wind occurs through deflation is "True".
<u>Answer:</u> Option A
<u>Explanation:</u>
When the erosion occurs of surface materials or small particles which are loose in nature due to flow of high speed wind current in geological phenomenon than termed as "Deflation" .
These loose material belongs from plain areas of dry, uncemented sediments like which are present in dry lake beds, deserts, floodplains etc.
Deflation differs from wind abrasion because of the effect of particles borne by wind as the method of grinding away a solid object. Deflation reduces the surface of the soil which may produce a blowout which is a depression created by wind erosion on the surface of the land.
