Step-by-step explanation:
The chemist needs 381.6 milliliters for their experiment.
Answer:
1. 0.1635
2. 0.0026
Step-by-step explanation:
The computation of the probability in the following cases are as follows:
1.
Given that
Mean = 25 minutes
ANd, the standard deviation is 6.1 minutes
So here the z score would be
= (31 - 25) ÷(6.1)
= 0.98
Now the probability is
= P(Z>0.98)
= 0.1635
2. the z score would be
= (8 - 25) ÷(6.1)
= -2.79
Now the probability is
= P(Z<-2.79)
= 0.0026
In order to get the answer to this question you will have to figure out how much 120 US dollars gets you in Canadian dollars.
Therefore your answer is "104.87."
Hope this helps.
