904.75
Step-by-step explanation:
The area of a semicircle: r^2
/2
Answer:
Let the unit of ratio be a.Then,the divided parts will be 3a,5a,4a and a.
A/q,
=>3a+5a+4a + a = 182.
=>13a = 182
=>a = 182/13
=>a = 14.
Hence,the smallest part = 14
I believe this problem has the following table for long
distance call:
0-1 minutes 2-5 minutes 6+ minutes
Long distance 170 120 10
To solve this problem, let us first recall what
probability means:
Probability = number of successful event / number of
total events
In this case, an event is considered to be successful
when the long distance call is not 6+ minutes long. Therefore:
number of successful event = 170 + 120 = 290
Now the number of total events is the sum of all number
of calls, hence,
number of total events = 170 + 120 + 10
number of total events = 300
Probability that the call is not 6+ minutes long is
therefore:
Probability = 290 / 300
Probability = 0.9667
or
Probability = 96.67%
