Answer:
In words we can say that there are seven times twenty four i.e, one hundred and sixty eight hours.
Step-by-step explanation:
In this question, we need to use words to describe the relationship between corresponding numbers of hours and weeks.
In a day,there are twenty four hours and there are seven days in a week .
Number of hours in a day = 24 hours
Number of hours in a week = Total number of hours in 7 days =
On mutiplying 24 by 7, we get
Number of hours in a week = 168 hours
Therefore, in words we can say that there are seven times twenty four i.e, one hundred and sixty eight hours.

Answer:
The probability that the assembly line will be shut down is 0.00617.
Step-by-step explanation:
We are given that a soda bottling company’s manufacturing process is calibrated so that 99% of bottles are filled to within specifications, while 1% is not within specification.
Every hour, 12 random bottles are taken from the assembly line and tested. If 2 or more bottles in the sample are not within specification, the assembly line is shut down for recalibration.
Let X = <u><em>Number of bottles in the sample that are not within specification</em></u>.
The above situation can be represented through binomial distribution;
where, n = number of trials (samples) taken = 12 bottles
x = number of success = 2 or more bottles
p = probabilitiy of success which in our question is probability that
bottles are not within specification, i.e. p = 0.01
So, X ~ Binom (n = 12, p = 0.01)
Now, the probability that the assembly line will be shut down is given by = P(X 2)
P(X 2) = 1 - P(X = 0) - P(X = 1)
=
=
= <u>0.00617</u>
