X² + y² - 8x - 12y + 52 = 36
x² - 8x + y² - 12y + 52 = 36
x² - 8x + y² - 12y = 88
(x² - 8x + 16) + (y² - 12y + 36) = 88 + 16 + 36
(x - 4)² + (y - 6)² = 138
(h, k) = (x, y) = (4, 6)
        
                    
             
        
        
        
I believe it's 3 months because 12 divided by 4 is 3.
        
                    
             
        
        
        
<span>6840 customers ... 45 days<span>
x customers = ? ... 1 day
If you
would like to know how many customers were in Jasigreen's class in 1 day,
you can calculate this using the following steps:
6840 * 1 = 45 * x
6840 = 45
* x     /45
x = 6840 / 45
x = 152 customers
<span>The
correct result would be </span>152 customers<span>.</span></span></span>
        
             
        
        
        
Answer:
Step-by-step explanation:
Hello!
The standard deviation (δ) is a measure of variability, this means, it shows how dispersed the data set is with respect to the mean. The population mean (μ) is a measurement of position. The three graphics have the same position μ=0 but their standard deviations change, this means, the form of their bells is different. The greater the value of the standard deviation, the more dispersed the data is you can see this graphically because the width of the bell will be greater.
Graph attached.
I hope it helps!
