Total marbles = 5 + 10 + 3 + 7 = 25

Total marbles that are not red = 10 + 3 + 7 = 20

P(Not red marble) = 20/25 = 4/5

Answer: 4/5

Hello!

First you have to find how many marbles there are

5 red
10 blue
3 yellow
7 green

Add these up

5 + 10 + 3 + 7 = 25

To find the probability of not choosing a red marble you put the amount of marbles that are not red over the total amount of marbles

20 non-red marbles
25 marbles in total

So the probability is 20/25

This can be simplified to 4/5

The answer is 4/5

Hope this helps!

A rectangular lap pool measures 80 feet long by 20 feet wide if it needs to be filled to 48 and each cubic foot hose 7.5 gallons
zmey [24]

Answer: it will take 576000 gallons to fill the lap pool.

Step-by-step explanation:

The formula for determining the volume of water in the rectangular pool is expressed as

Volume = length × width × height

The rectangular lap pool measures 80 feet long by 20 feet wide if it needs to be filled to 48. It means that the volume of water that would be pumped inside the pool is

Volume = 80 × 20 × 48 = 76800 cubic feet

1 cubic foot = 7.5 gallons

76800 cubic feet = 76800 × 7.5 = 576000 gallons

Which is the equation of the parabola?
mestny [16]

Answer:

  • y = -1/20(x + 3)²

Step-by-step explanation:

<u>Consider the parent function:</u>

  • y = x²

The graph of the function open up and the vertex is at the origin, the point (0, 0)

Now, if it opens down, it means it is a reflection of the parent function over x axis, hence it has a negative coefficient, the function becomes:

  • y = -x²

The vertex is shifted to the point (-3, 0). It means the function also translated left by 3 units, the function becomes:

  • y = -(x + 3)²

<u>Since all the options have 1/20 as a coefficient, our function is:</u>

  • y = -1/20(x + 3)²

This is option B
