Answer: 146.24 square meters
Step-by-step explanation:
Answer:
Answer down below!
Step-by-step explanation:
1) 10
2) 4
3) 6
----------------
1 ) we know that perimeter = all the sides combined.
- (44 is the given perim.; so therefore if 12x2+10x2=44, 20 is the missing width.
2 ) we know that area = lw.
- 44 is the given area, so therefore if 10x4=40, 4 is the base.
3 ) we know that area = lw.
we need to find the area of the square. 3 x 2 = 6. 6 is the area of the missing square or the part that needs to be covered.
They are congruent. Distance formula works.
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
