C .. its c because if you subtract it thats what you will get
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:
94.6666666667
Step-by-step explanation:
use a calculator...or you can just divide both those numbers by two and simplify the question
sorry but there are no drawings
Answer:
Part A = 3 years
Part B = $3400
Step-by-step explanation:
To find this, we can model the value of the computer as V = A(.5)^x, in which x is the number of years. To find how long it takes to get to 12.5%, we can ignore all but the exponential part of the function and set equal to the percentage.
.125 = (.5)^x
3 = x
To find the initial value of the computer, use the formula created and solve for A.
V = A(.5)^x
425 = A(.5)^3
425 = A(.125)
3400 = A
