First do the the parenthesis: (6-3) = 3
Now you have [-4 + 3 * 8] -10
Next do multiplication: 3 *8 = 24
Now you have [-4 + 24]-10
Now do what is in brackets: -4 + 24 = 20
Now you have 20-10
Subtract 20-10 = 10
Answer: 0.025
Step-by-step explanation:
The probability density function for a random variable that is uniformly distributed on interval [a,b] is given by :-
Given : A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 45.0 and 55.0 minutes.
Let x be the random variable that denotes the lengths of her classes.
Then, the probability density function =
Now, the probability that a given class period runs between 50.25 and 50.5 minutes will be :-
Hence, the required probability =0.025
2 times negative 3 equals negative 6
