Answer:
option C.
Step-by-step explanation:
The given graph is the bell shaped graph.
From the graph we can observe that the peak is at 69.
So, the mean of the data is = 69 .
Standard deviation is the deviation of the graph from the mean value.
= 72-69 = 3
Hence, the standard deviation is equal to 3.
So, the correct answer is option C.
To solve this problem you must apply the proccedure shown below:
By definition, an equilateral triangle has equal sides and all its internal angles are . If you divide it into two right triangles, you can apply the Pythagorean Theorem to calculate the height of the triangular base of the pyramid, as following:
Therefore, as you can see, the answer is:
Answer:
Option A is correct one
The opposite angle is equal to its side
Side ab>ac>cb
angle C >B >A
So you can go with it

THANK YOU........
A^2 + b^2 = c^2
a^2 + (12)^2 = (13)^2
a^2 + 144 = 169
a^2 = 169 - 144
a^2 = 25
Sqrt (a^2) = Sqrt(25)
a = 5

Outliers affect the mean value of the data but have little effect on the median or mode of a given set of data.
