Two roller coasters are vying for the title of the steepest drop the first ride has a hill that drops 140 feet in a 40 foot run
muminat

Answer:

They have the same slope

Step-by-step explanation:

Given

Coaster 1:

Drops = 140ft

Run = 40ft

Coaster 2:

Drops = 105ft

Run = 30ft

First, we calculate the slope (m) of both coasters

m = \frac{Rise}{Run}

m = \frac{Drops}{Run}

For coaster 1:

m = \frac{140ft}{40ft}

m = \frac{140}{40}

m = 3.5

For coaster 1:

m = \frac{105ft}{30ft}

m = \frac{105}{30}

m = 3.5

<em></em>m = m=>3.5 = 3.5<em></em>

<em>By comparison, they have the same slope</em>

MAD: 6.4

2.

Mean: 60.5

MAD: 6.4

3. The diference of the means are 4.5

I’m sorry, I do not understand the last one.

Step-by-step explanation:

The mean is the average, add all of the values and divide the result by the number of values. The MAD is the mean absolute deviation. You find it by taking the distance between the values and the mean. You then add them together and divide it by the mean. I really hope this helps you!
