A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 46.0 and 56.
barxatty [35]

Answer: 0.05

Step-by-step explanation:

Given : Interval for uniform distribution : [46.0 minutes, 56.0 minutes]

The probability density function will be :-

f(x)=\dfrac{1}{56-46}=\dfrac{1}{10}=0.1\ \ , 46

The probability that a given class period runs between 50.75 and 51.25 minutes is given by :-

P(50.75

Hence, the probability that a given class period runs between 50.75 and 51.25 minutes = 0.05

3(x + 4) = 3x + 12 solve for x
iris [78.8K]

Answer:

all real numbers.

Step-by-step explanation:

First, distribute 3 to all terms within the parenthesis:

3(x + 4) = 3(x) + 3(4) = 3x + 12

3x + 12 = 3x + 12

Because both sides are the same, your answer for x is "all real numbers".
