A roller coaster climbs 120 feet from ground level then drops 75 feet before climbing another 105 feet. How far above ground is
Ostrovityanka [42]

Answer:

The roller coaster is 155 feet above the ground.

Step-by-step explanation:

Given:

The roller coaster climbs 120 feet from ground level.

Then drops 75 feet

Then again climbs 105 feet

To find distance of roller coaster above the ground now we will subtract the drop in level from the rise and then add the second rise to the difference.

This can be evaluated as:

125\ ft-75\ ft+105\ ft

⇒ 50\ ft + 105\ ft

⇒ 155\ ft

Thus the roller coaster is 155 feet above the ground.

This interval is calculated using the sample proportion. The sample proportion in this case is based on a number of samples examined. The interval we obtain in this case (0.6904; 0.8218) is the estimated range which we expect the population proportion to fall ; with a 95% confidence.
