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.
Let the width be x m, then the length is 2x-7 m.
If the length is decreased by 1m, then new length is 2x-7-1=2x-8 m.
If the width is decreased by 4 m, then new width is x-4 m.
Find the perimeter of new recangle:
The perimeter of new rectangle is 66 m, then
Therefore, old width was 15 metres and old length was 2·15-7=23 metres.
Answer: original width: 15 metres, original length: 23 metres
