Peter has just returned from the Philippines and wants to exchange his remaining

A driver is 15 feet below the surface of the water 10 seconds after he entered the water and 90 feet below the surface after 40

spin [16.1K]

Answer:

$\frac{-75ft}{30sec}$ or simplified would be $\frac{-2.5ft}{sec}$

Step-by-step explanation:

In order to calculate the rate of change, we must subtract his end position and end time by the starting position and starting time. We are using the -15 feet since it is below the surface area as the starting position and the 10 seconds as the starting time. We make each of these into a fraction and subtract like so...

$\frac{-90ft - (-15ft)}{40sec - 10sec} =$ rate of change

$\frac{-75ft}{30sec} =$ rate of change

$\frac{-2.5ft}{sec}$ = rate of change

Therefore, we can see that the rate of change of the diver is $\frac{-75ft}{30sec}$ or simplified would be $\frac{-2.5ft}{sec}$

Look at the shape of the graph what can you predict about the mean and median beverage prices

The mean price and median price are close together.

Answer: Option 2

<u>Explanation:</u>

The shape of the graph which is shown in the picture is symmetric. Since it is symmetrical in shape, most of the data is clustered together around the center. This center is the median. The mean will be close to the median, since most of the data values are close to this.

The graph shows that the prices of the beverages are some where near and close to each other. The prices are not at extreme ends and this makes the shape of the graph symmetrical. Had there been any kind of extreme ends, then the shape of the graph would not have been the same.

Ralph says he can rewrite (4+5)+21 as 9+21. Do you agree ?why or why not?

noname [10]

I agree because parentheses always go first and 4+5 equals 9 so in conclusion ralph is correct and the answer would be 30
