Step-by-step explanation:
2 of a white ball =2/30 =1/15;
This is the probability of picking a black ball.
Let the number of black ball be X
x/(x +20)= 1/15[ probability of picking black ball ]
15x = x + 20 ; by cross multiplication
14x=20; x = 20/ 14 =1.42 = 1 [ approximately]
But to satisfy the premise given above; we have to approximate the no of balls to 2

Answer:
<em>The table shows a proportional relationship: YES</em>
<em>The constant of proportionality is k=7</em>
<em>y = 7x</em>
Step-by-step explanation:
<u>Proportions</u>
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
y = kx
Where k is the constant of proportionality. It can be calculated by solving the equation for k:

We are given a table with 4 pairs of values. If the relationship between the variables is proportional, then the ratio y/x should be constant.
Let's verify some points:




Since all the ratios are equal,
The table shows a proportional relationship: YES
The constant of proportionality is k=7
The equation for the relationship is
y = 7x
Answer:
if you just want 14% of 88
14% of 88 = 12.32, 0.14 * 88
if you want 14% of 88 + 88
114% of 88 = 100.32, 1.14 * 88
Step-by-step explanation:
2% of x = 0.02 * x
20% of x = 0.2 * x
200% of x = 2 * x
