Draw a diameter through the center of the circle. Any radius of this circle is 1/2 the length of the diameter. Thus, if we divide the diameter into two equal parts, we have two lengths that form the ratio 2:1, where 2 represents the diameter and 1 the radius.
Answer:
7
Step-by-step explanation:
There are 7 days in a week, and she sent 49 messages by the end of the week. Assuming that she sent the same number of messages each day, we would take the number of messages and divide it by the number of days, 49 and 7. 49 divided by 7 is 7. She sent 7 messages each day!

Answer:
181 MP3 players
Step-by-step explanation:
Given data:
Replacement of MP3 that fail within 3 years
expected lifetime of MP3 = 5 years
number of MP3 players purchased = 1000
number of MP3 players replaced in the first year = ?
To determine the number of MP3 replaced in the first year we will employ this formula:

a = ∞
since the given problem is an exponential distribution
1/u = 5 hence u = 0.2
next we will determine the number of MP3's to fail in its first year of purchase
qo = failure
po = success
number of purchase = 1000
attached below is the remaining part of the solution
