Answer:
V=3888 in³
Step-by-step explanation:
V=πr^2h
V=π x 7.5^2 x 22
V=3888 in³
 
        
             
        
        
        
1. B 
Adding a constant offset to the data does not change its variance. Scaling it, or applying a non-linear function will change the variance.
2. A 
For a given number on the 3rd die, the first two dice can match it 11 ways, or have two numbers that match in 5 additional ways. Thus probability of 2 or more numbers being the same is 6*16/216 = 4/9.
        
             
        
        
        
<span>12x +3y = 12
y = -4x +5
 
We can convert the first equation to the same form as the second (y=mx+b, or slope-intercept).
 
12x +3y = 12
3y = -12x +12
y = -4x +4
 
Comparing the simplified first equation y = -4x +4 to the second equation y = -4x + 5, we see that both have the same slope (m = -4), but different y-intercepts (b = 4, b = 5). This means they are parallel lines, or an inconsistent system. There are no solutions.</span>
