k =1.89 is the constant of  proportionality that represents the  relationship between the cost, y, to the  number of pounds of potatoes, x .

<u>Step-by-step explanation:</u>

Here we have , The cost of 2 pounds of potatoes is  $3.78. We need to find  the constant of  proportionality that represents the  relationship between the cost, y, to the  number of pounds of potatoes, x . Let's find out:

Cost is y &  number of pounds of potatoes is x  :

y = (k)x , where k is constant of  proportionality that represents the  relationship between the cost, y, to the  number of pounds of potatoes, x .

⇒ y = (k)x

⇒ 3.78 = (k)2

⇒ \frac{3.78}{2} = \frac{(k)2}{2}

⇒ \frac{3.78}{2} =k

⇒ k =1.89

Therefore, k =1.89 is the constant of  proportionality that represents the  relationship between the cost, y, to the  number of pounds of potatoes, x .

Maria has a bag with 6 red marbles, 6 blue marbles, and 4 green marbles looking Maria picks one . She does not replace it and sh
Sati [7]

Answer: Hello there!

initially Maria has 6 red marbles, 6 blue marbles, and 4 green marbles.

You know that in the first pick, Maria gets a green marble ( this means that now there are 3 green marbles left)

Now we want to know the probability that she gets a red marble on the second pick.

Now there are 6 + 6 + 3 = 15 marbles in the bag, and 6 of them are red ones. Then the probability of getting one red is the number of red ones divided by the total amount ( which is the ratio of red marbles to total marbles)

this is 6/15.

now you can see that there is no 6/15 in the options, so we need to see which one is equivalent.

if we took the option C, 2/5, and multiply both denominator and numerator by 3, we get (3*2)/(3*5) = 6/15, then 2/5 and 6/15 are equivalents.

Then the correct answer is C.
