Little tip....notice how ur y coordinates are the same....this means that u have a horizontal line which is represented by y = a number...with that number being the y coordinate of ur points.
So ur equation is : y = -3 <===

** if ur x's would have been the same, it would be a vertical line represented by x = a number...with that number being the x coordinates of ur points...but thats only if ur x coordinates were the same

Answer:

Step-by-step explanation:

0.71=71%.

2/100+2/100=4/100/4%

So we can subtract 71-4=67.

That tells us that the missing number is 67. Add it all up and you will get 0.71 or 71%

Answer:

Amir: 2/3

Whitney: 1/4

Step-by-step explanation:

We can let w represent the fraction Whitney eats. Then the fraction Amir eats is (w+5/12). The total amount they eat is found by ...

w + (w +5/12) + 1/12 = 1

2w = 1/2 . . . . . subtract 6/12

w = 1/4 . . . . fraction Whitney eats

w+5/12 = 3/12 +5/12 = 8/12 = 2/3 . . . . fraction Amir eats

Answer:

The total number of marbles in the bag is 50.

Step-by-step explanation:

Here, we have n trials, without replacement. So the hypergeometric distribution is used.

The mean of the hypergeometric distribution is:

$E(X) = \frac{n*k}{N}$

In which n is the number of items in the sample, k is the number of items in the population that are classified a success and N is the size of the population.

15 marbles are drawn:

This means that $n = 15$
