Answer:
   m∠V ≈ 61°
Step-by-step explanation:
The hypotenuse and the side opposite the angle of interest are given. The relevant trig relation is ...
   Sin = Opposite/Hypotenuse
   sin(V) = XW/XV = 7/8
The inverse sine function is used to find the angle:
   V = arcsin(7/8) ≈ 61°
 
        
             
        
        
        
3 times 7= 21 times three =63
        
             
        
        
        
Answer: D
Step-by-step explanation:be cause you have to add 4 to negetive 5 and and that negetive 1 which is greater than -5
 
        
             
        
        
        
The variance of a distribution is the square of the standard deviation
The variance of the data is 2.2
<h3>How to calculate the variance</h3>
Start by calculating the expected value using:

So, we have:

This gives

Next, calculate E(x^2) using:

So, we have:


The variance is then calculated as:

So, we have:


Approximate

Hence, the variance of the data is 2.2
