The value of cement mixer after t year is
Given to us
The value of cement mixer when bought, = $ 54,205
the value of cement mixer after 1 year, = $ 47,158. 35
the value of cement mixer after 2 year,= $ 41,027. 76
To find out depreciation we can use the formula for depreciation,
By putting the value, in the formula we get,
Therefore, putting the value of and
in depreciation formula for
years we get,
Hence, the value of cement mixer after t year is .

Answer:
Required probability is 0.784 .
Step-by-step explanation:
We are given that in a large statistics course, 74% of the students passed the first exam, 72% of the students pass the second exam, and 58% of the students passed both exams.
Let Probability that the students passed the first exam = P(F) = 0.74
Probability that the students passed the second exam = P(S) = 0.72
Probability that the students passed both exams = = 0.58
Now, if the student passed the first exam, probability that he passed the second exam is given by the conditional probability of P(S/F) ;
As we know that conditional probability, P(A/B) =
Similarly, P(S/F) = =
{As
is same as
}
= = 0.784
Therefore, probability that he passed the second exam is 0.784 .
