Examine each set of functions and determine which has the greater rate of change, if either. Explain your reason.

Answers

Answer:

The Spotted Cows delivery service has a greater rate of change.

Explanation

The Spotted Cows function is: y = 2.8x + 2

Dairy Farms function is: y = 2.1x + 10

I have graphed these two functions to determine which has a greater rate of change. The red line represents the Spotted Cow service while the blue represents the Dairy Farms service. On the graph you can see that the red line intersects and shifts above the blue line, meaning the rate increases at a higher rate than the blue.

- Each friend has 10 nails to paint

- There are 8 friends

- Jackie finished painting 4 friend's nails

If there are 8 friends, and each friend has 10 nails to paint, then there are 80 nails that need to be painted in total.

Jackie finished painting 40 nails.

So the math sentence will be:

80 - 40 = 40

You pull a marble from a bag with 20 red 20 white and 10 green marbles. You hold onto it and then pull another marble. What is the probability of pulling a red marble and then pulling a green marble?

Answers

I don’t know man sorry that’s my fault

The probability of pulling a red marble and then pulling a green marble is,

⇒ 3 / 5

What is mean by Probability?

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

We have to given that;

You pull a marble from a bag with 20 red 20 white and 10 green marbles.

Here, Total number of marbles = 20 + 20 + 10

                                                = 50

Thus, The probability of pulling a red marble is,

⇒ 20 / 50

⇒ 2 / 5

And, The probability of pulling a green marble is,

⇒ 10 / 50

⇒ 1 / 5

Therefore, The probability of pulling a red marble and then pulling a green marble is,

⇒ 2 / 5 + 1 / 5

⇒ 3 / 5
