Answer:

k = \frac{1}{2}

Step-by-step explanation:

Given

x 2 4 6 8

y 1 2 3 4

Required

Determine the constant of proportionality (k)

The relationship between x and y is:

y = kx

When y = 1, x = 2;

So, we have:

1 = k * 2

2 * k = 1

Make k the subject

k = \frac{1}{2}

Hence, the constant of proportionality is 1/2

jarptica [38.1K]

Answer: 150 students participate in sports only.

Step-by-step explanation: In a venn diagram, 50 goes in the middle section for the 50 students that participate in both music and sports. 50 also goes on the side for music only. That makes 100 students. 150 goes on the sports only side because 150 + 50 + 50 = 250 students that attend the school.
