\mathbb P(35\le X\le45)=\mathbb P(X\le45)-\mathbb P(X\le35)=F_X(45)-F_X(35)

where F_X(x) is the cumulative distribution function of X. We have probability density given by

f_X(x)=\begin{cases}\frac1{10}&\text{for }40\le x\le50\\\\0&\text{otherwise}\end{cases}

which yields the CDF

F_X(x)=\begin{cases}0&\text{for }x

and so

\mathbb P(35\le X\le45)=\dfrac{45-40}{10}-0=\dfrac12

Nicholas wrote the steps below to simplify the fraction 20/30 find his error and correct it
Dmitrij [34]
Unfortunately, Nicholas' steps in simplifying the fraction is not reflected in the question. However, the general idea of the simplifying fraction is to find the greatest common factor (GCF) of both the numerator and the denominator. In this case, the GCF is 10. Then, divide both numbers by the GCF. The answer for this item should be 2/3.

Which institution informs individuals and businesses about their rights and responsibilities?
Mama L [17]

Answer:

A. The Federal Trade Commission

Step-by-step explanation:

The FTC inaugurated its doors in March 1915. The FTC's purpose is to protect consumers and encourage contestants. The FTC cannot solve individual grievances, but it can present knowledge about what steps to exercise. The FTC states that accusations can improve it and its law implementation partners identify patterns of fraud and exploitation, which may direct to examinations and preventing unfair marketing practices.
