A proportional relationship has the form: y=mx
The first three options (y=(1/3)x, y=2x, and y=3.4x) have this form. The fourth option is:
y+1=2x
If we isolate y:
y+1-1=2x-1
y=2x-1, it does not have the form y=mx
Answer: The equation that does not represent a proportional relationship is: Fourth option: y+1=2x

How to use replacement in probability
dolphi86 [110]

Step-by-step explanation:

Replacement means the probability of each trial is the same (the trials are independent).

For example, let's say you have a standard deck of 52 cards, and you want to find the probability of drawing a queen card twice.

There are 4 queens, so the probability on the first draw is 4/52.

You then replace the queen, so there are still 4 queens in the deck.  So the probability on the second draw is still 4/52.

The total probability is the product: 4/52 × 4/52 = 1/169

If you didn't replace the queen after the first draw, there would have been 3 queens in the deck, and the probability on the second draw would have been 3/52.

On a trip, you had to change your money from dollars to euros. You got 450 euros for 600 dollars. Which is a unit rate that desc
chubhunter [2.5K]
The number of Euros received against 600 dollars = 450
Then
For 1 dollar, the number of euros = (450/600) euros
                                                       = (45/60) euros
                                                       = ( 3/4) euros
                                                       = 0.75 euros
So the unit rate that describes the exchange rate is 0.75 euros per dollar. So the correct option among all the options given in the question is option "A". I hope the procedure for getting to the correct result is clear enough for you to understand. In future you can use this procedure for solving similar problems.
