Step-by-step explanation:
Given: The translated equation :
To find the value of x if y = 87.5, we need to substitute the value of y in the given translated equation, we will get
Subtract 87.5 from both the sides , we get
Now, divide 300 on both the sides, we get
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.
