By applying Pythagoras theorem,we get
(hypotenuse)^2=(base)^2+(perpendicular)^2
=>(h)^2=(7)^2+(4)^2
=>(h)^2=49+16
=>(h)^2=65
=>h=√65
Therefore, option B is correct,i.e.,√65
Answer:
For the first graph, the slope is -1/3.
For the second graph, the slope is 3
Step-by-step explanation:
Slope is can be found by doing rise over run. Count how many it rises vertically and how many it goes across horizontally. Use the rise over run to get the answer. The first one is negative because the line slopes down.
Answer: b. 30%
Step-by-step explanation:
- A measure of relative variability is known as coefficient of variation. It is the ratio of the standard deviation to the mean.
i.e. 
Given: mean = 
Variance = 
Now, 
in percent , 
Hence, correct option is b. 30%.
