Answer:

Negative Correlation

Answer:

D. y = 5\cdot \Sigma_{i=0}^{4} \left(\frac{1}{3} \right)^{i}

Step-by-step explanation:

Let be y = \Sigma_{i = 0}^{4} \left[5\cdot \left(\frac{1}{3} \right)^{i}\right]. To find the equivalent expression we must use the following property:

y = c\cdot \Sigma_{i = 0}^{n} p(x) = \Sigma_{i=0}^{n} [c\cdot p(x)] (1)

Based on this fact, we find the following equivalence:

y = 5\cdot \Sigma_{i=0}^{4} \left(\frac{1}{3} \right)^{i}

Hence, the correct answer is D.

rusak2 [61]
Ratio is 5girls:7boys with total 72 students
5+7= 12
72➗12= 6
6(5:7)= 30 girls : 42 boys

New ratio is 3:4 with 48 boys

48➗4= 12

So for girls 3x12= 36

So started with 30 girls ended with 36 girls... 6 girls joined band during the school year.
