An insurance company selected a random sample of 500 clients under 18 years of age and found that 180 of them had had an acciden
adoni [48]

Answer: The accident proportion differ between the two age groups is 0.11.

Step-by-step explanation:

Since we have given that

Number of clients under 18 years of age = 500

Number of clients had had an accident = 180

Proportion of client had an accident = \dfrac{180}{500}=\dfrac{18}{50}

Number of clients aged 18 and older = 600

Number of clients had had an accident = 150

Proportion of client had an accident = \dfrac{150}{600}=\dfrac{15}{60}

So, According to question, we get that

Difference between the two age groups proportions would be :

\dfrac{18}{50}-\dfrac{15}{60}\\\\=\dfrac{108-75}{300}\\\\=\dfrac{33}{300}\\\\=\dfrac{11}{100}

Hence, the accident proportion differ between the two age groups is 0.11.

What percent of 75 is 40
9966 [12]

The answer is: " 53 \frac{1}{3} % " .

__________________________________________

→ " 53 \frac{1}{3} % " of 75 is "40" .

__________________________________________

Explanation:

To solve:

\frac{x}{100} * 75 = 40 ;

→ Rewrite as:

\frac{x}{100} * \frac{75}{1} = 40 ;

→ The "100" cancels to "4" ; and the "75" cancels to "3" ;

→ {since: "{100 ÷ 25 = 4}" ; and since: "{75 ÷ 25 = 3"} ;

→ So; we rewrite the problem as:

→ \frac{x}{4} * \frac{3}{1} = 40 ;

→ which is:

\frac{x}{4} * 3 = 40 ;

→ Divide each side of the equation by "3" ;

\frac{x}{4} * 3 ÷ 3 = 40 ÷ 3 ;

to get:

→ \frac{x}{4} = \frac{40}{3} ;

Now, cross-multiply:

→ 3x = (4)*(40) ;

→ 3x = 160 ;

Divide each side of the equation by "3" ;

to isolate "x" on one side of the equation; & to solve for "x" ;

→ 3x / 3 = 160 / 3 ;

to get:

→ x = 53 \frac{1}{3} .
