Yes it is because if you multiply 3*3=9 
then what you do on top you do on the bottom 10*3=30
        
                    
             
        
        
        
Answer:
Usually, the presence of an outlier indicates some sort of problem. This can be a case which does not fit the model under study, or an error in measurement. Outliers are often easy to spot in histograms. 
Step-by-step explanation:
 It is similar to a Bar Chart, but a histogram groups numbers into ranges
 
        
             
        
        
        
Your inequality would be:   400 <span> ≥  15.50x + 150</span>
        
             
        
        
        
Answer:
<em>y=-6</em>
Step-by-step explanation:
<em>Geometric Sequences</em>
Any given sequence is said to be geometric if each term  can be obtained as the previous term
 can be obtained as the previous term  by a constant value called the common ratio.
 by a constant value called the common ratio.

or equivalently

Looking closely at the sequence 2, y, 18,-54, 162 we can try to find out if it's a geometric sequence or not. We compute the possible common ratios
 and we see they both result -3. If we use r=-3 and try to find the second term (y), then
 and we see they both result -3. If we use r=-3 and try to find the second term (y), then
y=2*(-3)=-6
Now we compute the third term: (-6)(-3)=18
Since we got the third term as given in the original sequence.
So y=-6
