Given:
A metal is made from copper, zinc and lead in the ratio 13:6:1.
The mass of zinc is 90kg.
To find:
The mass of the metal.
Solution:
It is given that the metal is made from copper, zinc and lead in the ratio 13:6:1.
Let the mass of copper, zinc and lead are 13x, 6x and 1x respectively.
The mass of zinc is 90kg. So,
Now, total mass of the metal is:
Therefore, the mass of the metal is 300kg.
A) The probability of Lisa being correct if she says a drink is flat is; 83.3%
B) The level of Lisa's accuracy in detecting a drink that is flat is; 83.3%
C) The reason why Lisa should be considered for to job is because; she has a high accuracy level and is not just complaining unnecessarily.
<h3>How do you interpret the right probability?</h3>
From the table showing Lisa's response to the last 100 drinks she bought attached, we see that;
A) When the drink was flat, she complained 5 times out of 6. Thus, if the drink is flat, the probability of her complaint being correct = 5/6 = 83.3%
B) Since she is 83.3% correct in detecting whether a drink is flat, then we can say that Lisa is 83.3% very good at detecting whether a drink is flat.
C) It would be good in recommending Lisa for the quality control job because she only complained 3 times out of 94 times that the drink was not flat while she was correct 5 out of 6 times when the drink was flat. Thus, she has a high accuracy level and is not just complaining unnecessarily.

Answer:
They will reach after 26 hours i.e tomorrow noon
Step-by-step explanation:
Start time = 10 a.m
Starting point marker = 2 mile
End point = 80 miles
Distance to be traveled = 80 - 2 = 78 miles
Average speed = 3 miles per hour
Now,
Time =
or
Time =
or
Time = 26 hours
Therefore,
They will reach after 26 hours i.e tomorrow noon
