Answer:
The constant of variation in a direct variation is the constant (unchanged) ratio of two variable quantities. The formula for direct variation is. y = k x (or y = k x ) where k is the constant of variation . Example 1: If y varies directly as x and y = 15 when x = 24 , find x when y = 25 .

Step-by-step explanation:
it literally doubles in size
The equation representing the cost of 6 chairs and a table is:
6x + x + 50 = 750
⇒
7x = 700
This equation is true for x = 100 because:
7(100) = 700
So, the cost of one chair will be $100.
Cost of table is $50 more than a chair, so the cost of one table is $150.
So the answers are:
$ 100
$ 100
$ 150
Reference to a standard normal distribution table shows that for a cumulative probability of 0.6064 the z-score is 0.27.
