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: 21y^5-28y^4+49y^3
If the remainder isn't necessarily zero, we add C_1y^2+C_2y+C_3, which covers all possible remainders when dividing by a polynomial with leading term in y^3.
Step-by-step explanation:
(3y^2-4y+7)(7y^3) =
21y^5-28y^4+49y^3
Answer:
c
Step-by-step explanation: sorry I'm late but I got a 100
Determine the area of the circular region that can be reached by the radio station signal using the equation.
A = πD²/4
A is area and D is diameter. Using 3.14 as pi value.
A = (3.14)(120 mi)² / 4
A = 11304 mi²
Knowing that in each of the squared miles, 100 people live.
total population receiving the signal = 11304 mi² x (100 people / 1 mi²)
= 1,130,400
Thus, the answer is letter C.
