Answer:
$1719.55, 61.4%
Step-by-step explanation:
Original price of stove: $2,800
Value of stove after 1 year: (1 - 0.15)($2,800), or 0.85($2,800) = $2,380
Value of stove after 2 years: 0.85($2,380) = $1719.55
Find the ratio of this last result to the original price and convert that to a percentage:
$1,719.55
-------------- = 0.614, or approximately 61.4%
$2,800

Answer:
1.4% of connectors fail during the warranty period.
Step-by-step explanation:
We have these following probabilities:
A 90% probability that a connector is kept dry.
A 10% probability that a connectors is wet.
If a connector is dry, an 1% probability of failling.
If a connector is wet, a 5% probability of failling.
What proportion of connectors fail during the warranty period?
This is 1% of 90% and 5% of 10%. So
1.4% of connectors fail during the warranty period.
64 - (13 - 7) = 64 - 6 = 58
