Answer:
$4
Step-by-step explanation:
The equation for direct proportionality =
y = bx
where y = dependent variable
b = constant
x = independent variable
There is positive proportionality is two variables are positively related to each other.
In this question, price of lunches is the dependent variable while number of lunches is the independent variable
$16 = b4
Divide both sides by 4 to find b
b = $4

Answer:
Step-by-step explanation:
Red = 6
Blue = 3
Green = 5
Total = 14
First marble = 6/14 = 3/7 You now have 5 reds and 13 total
Second Marble = 5 * 13 which brings you down to 4 red and 12 total.
Third Marble = 4/12 = 1/3
Result
P(3 Red) = 3/7 * 5/13 * 1/3 cancel the 3s
P(3 Red) = 1/7 * 5/13
P(3 Red) = 5/91
P(3 Red) = 0.0549 . Rounding to the nearest 1/100 depends on what you have been told about rounding. I would say the answer is 0.05 but your teacher may say something different.
