Suppose that y is directly proportional to x, and y = −16 when x = −2. What is the constant of proportionality?

A) −8
B) −
1
8
C) 1
8
D) 8

Answers

Answer:

In the given expression the constant of proportionality is  k = 8.

Step-by-step explanation:

The quantity P is said to be directly proportional to Q if they vary in proportion to each other.


Here, P ∝ Q ⇔  P = kQ : k = Proportionality Constant


Now, here given y ∝ x   and x =  -2, y = -16

Now, y ∝ x ⇒  y =  kxor, (-16)   = k (-2) or, k = 16/2  = 8 ⇒ k = 8So, for k = 8, y ∝ x 

Hence, in the given expression the constant of proportionality is  k = 8.

Its A because the ratio from females to males ls 5:3

Answer:

B. He should focus on females because the ratio of females to males is 5:2.

Step-by-step explanation:

By looking at the graph, you can see that there are 25 females and 10 males. The ratio for this is 25:10, but we can simplify by dividing both sides by 5! 25/5=5, and 10/5=2, so the simplified ratio of 25:10 is 5:2. If you look at all of the answer choices, you really don't have to look at the words a lot; there's only one choice that includes the ratio 5:2. That choice is B, so B is the answer!
