Even if you don't solve for the correlation coefficient, you can already solve this by process of elimination and inspection. The correlation coefficient has a positive value, therefore, it's not D. Looking at the data, you can see a trend in the values; as one data increases, the other increases as well. Therefore, the dependency of the variables is strong and the correlation coefficient must be close to 1. So, the answer is B.
Answer:
1793.055556
Step-by-step explanation:
Divide the number by 60 * 24. (That will get the number of days.)
Divide the remainder by 60. (That will give you number of hours.)
The remainder of #2 is the number of minutes.
The goal of all algebra equations is to isolate the variable. In 3 step you should first make sure both variables are on the same side. To do that make sure you use the inverse.
For example:
6a + 9 = 3a + 15
because 3a is positive you're going to want to subtract it.
6a + 6 = 3a + 15
-3a -3a
_______________
3a + 6 = 15
Now it's a 2 step equation and you solve it on from there.
1.5 x 2 = 3 So you do 2.4 x 2 = 4.8 and the answer is 4.8 miles
15 apples... you would divide 40 by 8 to get 5, which you will then multiply by three to get the total amount of apples needed for 40 tarts.
