Step-by-step explanation:
because you go with you first answer bc its going to be right
Coefficient of variation is the ratio of the standard deviation to the mean (average)
Coefficient of variation = (standard deviation/mean) × 100

Answer:
A= 75.06 Sq Cm
Step-by-step explanation:
Please refer to the picture attached with this.
In ΔABD
AB = 8.5 , AD = 6 and say BD = x
Applying Pythagoras theorem in this triangle
Pythagoras theorem says

where c is the side opposite to the right angle, and b and a are the other two sides of the right angled triangle.




Hence side 
a = 6.02+19
a = 25.02
Now we apply the formula for area of a triangle which is given as

Where b is the base , here we have base as a = 25.02
h is the height , here h = 6
Putting these values in Formula we get



Hence Area of the triangle is 75.06 sq cm
Answer:
The third choice is the correct answer
Step-by-step explanation:
The set of ordered pairs which could be generated by an exponential function is

If we examine the y-values of this set of ordered pairs, we can see that they have a common ratio of



This makes it exponential.
