The dimensions on the blueprint of the living room is 3 in by 4 in
        
                    
             
        
        
        
The thousands place (1000) is the fourth number to the left of the decimal, so round that one either up or down based on the number just one spot closer to the decimal, in this case, the hundreds place (100).
so we have 32,420
we can ignore the numbers that are going to become zeros as a result of the rounding . .
32,400
let's round 32,XXX either up or down based on the value in the hundreds place. if that value is 5 or greater, than we round up. if it is less than 5, than we round down. 
4 is in the hundreds place, so we round down
32,000 is the answer
        
             
        
        
        
Answer:
28$ and christen sold 7 boxes while Rafael sold 4 
Step-by-step explanation:
lower common multiple so take 4 x 7 = 28 as then take the 28 and divide by how much Christen gets a box which is 4 and 28 divided by 4 is 7 
 
        
                    
             
        
        
        
Answer:
y = 7.8x + 26
Step-by-step explanation:
Given the following :
Pearson's r = 0.78
Average consumption of ice cream = 5 grams per week (m) with Standard deviation (sd) = 1.5 grams
Average weight = 65 kg with standard deviation of 15kg
Formular for the regression line :
General regression formula :
y = mx + c
y = predicted variable ; m = slope or gradient ; x = predictor variable ; c = intercept 
Gradient (m) = change in y / change in x 
m = (sd y / sd x) * r
m = (sd weight / sd ice cream) × r 
m = (15 / 1.5) × r
m = 10 × 0.78 = 7.8
Intercept:
mean of weight(y) - [Slope×mean of icecream(x)] 
65 - [7.8 × 5]
65 - 39 = 26
Hence, 
y = 7.8x + 26
