Answer:
88
Step-by-step explanation:
if the decimal is below 5 then round down
Step-by-step explanation:
Given that,
The diameter of the merry-go-round, d = 14 feet
Time taken, t = 6 seconds
Radius, r = 7 feet
The linear speed of the merry-go-round is given by :

Also,

Where
is the angular speed
So,

Hence, his linear and angular speeds are 7.33 m/s and 1.04 rad/s.
Answer:
$13.16
Step-by-step explanation:
For each individual spin, there are two possible outcomes:
- There is a 1 in 38 chance of winning $175.
- There is a 37 in 38 chance of losing $5.
The expected value for each spin is the sum of the products of each outcome by their respective probability.
In 50 spins, the expected value is:

You can expect to lose $13.16 if you spin the wheel 50 times.
