Using a calculator, the correlation coefficient is of 0.7649. Since the correlation is greater than 0.6, there is strong correlation.
<h3>What is a correlation coefficient?</h3>
- It is an index that measures correlation between two variables, assuming values between -1 and 1.
- If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
- If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.
Using a calculator, we insert the points (x,y) to find the coefficient. In this problem, the points are given as follows:
(1, 5), (4, 8), (8, 3), (13, 10), (19, 13)
The coefficient is of 0.7649. Since the correlation is greater than 0.6, there is strong correlation.

Tax= 85 times 7% = 85 times 0.07
tax =85 times 0.07 = 5.95
tax = 85 = 5.95 2= 90.95
the answer is 90.95
He can count and there is 6.5 blocks between his house and the park
1 : 40 = 6 : 240
On the ground the fence would be 240 inches long
240 / 12 = 20 feet long fnce
The total amount the Noah receives will be equal to his hourly payment multiplied by the number of working of hours added to the 500$ bonus which he received.
Now, Noah get 28$ per hour and he works for x hours. This means that the payment he gets for working = 28x
Then, we will add the $500 which he received as a bonus.
Doing this, we can get the expression that models his total payment as follows:
y = 28x + 500
