Since the population increases by 7 percent each year, we can multiply 850 by 1.07 seven times. In other words, we can do 850 • 1.07^7. This is equal to about 1365.

Answer:

Correlation between x and y is 0.9508

Step-by-step explanation:

We are given the following in the question:

Distance(x): 1 4 6 6 6 7

Days(y): 2 20 29 38 44 50

We have to find the correlation between x and y.

$\sum y = 183\\\sum x=30\\\bar{x} = \displaystyle\frac{\sum x}{n} = \frac{30}{6} = 5\\\\\bar{y} = \displaystyle\frac{\sum y}{n} = \frac{183}{6} = 30.5\\\\(x-\bar{x}) = -4,-1,+1,+1,+1,+2\\(y-\bar{y}) = -28.5,-10.5,-1.5,7.5,13.5,19.5\\\sum (x-\bar{x}) (y-\bar{y}) = 183\\\sum(x-\bar{x})^2 = 24\\\sum(y-\bar{y})^2= 1543.5\\$
