there are 4 banana smoothies, 1 strawberry smoothie and 1 watermelon smoothie in the refrigerator. without looking, what is the
Mamont248 [21]

There are four banana, one strawberry and one water-melon smoothies, six in all.

Assuming all smoothies are identical when we pick, then the probability of picking a particular one is one divided by the total number (of smoothies).

Since there are four banana smoothies, the probability of picking a banana smoothie is four divided by six, or four-over-six, or two-thirds.

There are now five smoothies remaining, of which three are banana. Therefore the probability of picking another banana is three-over-five, or three fifths.

The final probability is the product of the individual (we call it a two-step experiment), or two-third multiplied by three-fifths, equal to two-fifths, or forty percent.

Recall that if the first banana smoothie had been put back in the batch, the probability would come out different.

What is the vertex of the parabola whose equation is y = (x + 1) ^2+ 3
lora16 [44]

Answer:

The vertex is (-1, 3)

Step-by-step explanation:

The form this is in is called vertex form. We can express the equation using its base form.

y = a(x - h)^2 + k

Now we can identify the vertex as (h, k). By looking at the equation, we can see h is equal to -1 and k is equal to 3.
