$-\displaystyle\frac{1}{2} :1\frac{3}{4}$

First , convert the mixed number (the fraction we are dividing by in the given maths problem) into an improper fraction .

Multiply the whole part (1) times the denominator (4) and add the numerator . The result is the numerator of our fraction , and the denominator stays the same .

So now our maths problem looks as follows :

$-\displaystyle\frac{1}{2} :\frac{7}{4}$

Now turn the fraction you are dividing by over :

$-\displaystyle\frac{1}{2} *\frac{4}{7}$

Now multiply the numerator of the first fraction times the numerator of the second fraction :

Perform the same operation with the denominators :

-4/14

So the result is :

$-\displaystyle\frac{4}{14}$

Since the above fraction is not in it's simplest form , we divide the top and bottom by 2 (a common factor of both 4 and 14) :

$-\displaystyle\frac{2}{7}$

Suppose that the commuting time on a particular train is uniformly distributed between 42 and 52 minutes. Bold a. What is the pr

nikdorinn [45]

Answer: 0.2

Step-by-step explanation:

Given: The commuting time on a particular train is uniformly distributed over the interval (42,52).

∴ The probability density function of X will be :-

$f(x)=\dfrac{1}{b-a}\\\\=\dfrac{1}{52-42}=\dfrac{1}{10}, 42$

Thus, the required probability :-

$P(X$

Hence, the probability that the commuting time will be less than 44 minutes= 0.2
