The width of a rectangle is 2x + 4 and the length of the

iren [92.7K]

Given:

Width of a rectangle = $2x+4$

Length of the rectangle = $6x+12$

To find:

The ratio of the width to the length.

Solution:

We need to find the ratio of the width to the length.

$\text{Required Ratio}=\dfrac{\text{Width}}{\text{Length}}$

Putting the given values, we get

$\text{Required Ratio}=\dfrac{2x+4}{6x+12}$

$\text{Required Ratio}=\dfrac{2(x+2)}{6(x+2)}$

$\text{Required Ratio}=\dfrac{2}{6}$

$\text{Required Ratio}=\dfrac{1}{3}$

$\text{Required Ratio}=1:3$

Therefore, the ratio of the width to the length is 1:3.

<h2><u>N-FACTORIAL!</u></h2>

<h3> $\mathbb{ \color{brown} \: PROBLEM } \: \: \bold{{ \color{brown}{1}}} :$ </h3>

$\mathcal{SOLUTION: }$

$\: \bold{ \red{6!}= 6×5×4×3×2×1= \boxed{ \bold{ \blue{720}}}}$

Therefore, <u>the value of 6! is 720</u>.

<h3> $\mathbb{ \color{brown} \: PROBLEM } \: \: \bold{{ \color{brown}{2}}} :$ </h3>

$\mathcal{SOLUTION: }$

$\bold{3! \cdot 2! }\implies \bold{(3×2×1) \cdot( 2×1 )}$

$\: \: \: \: \: \: \: \: \: \: \: \: \implies \: \bold{ 6 \times 2} = \boxed{ \bold{ \blue{12}}}$

Therefore, <u>the value of the given expression is 12.</u>

A new restaurant with 134 seats is being planned. Studies show that 62% of the customers demand a smoke-free area. How many se

zzz [600]

Answer: 100

Step-by-step explanation:

Given : The total number of seats planned in new restaurant =134

The percentage of customers demand a smoke-free area = 62%

It can also be written as $62\%=\dfrac{62}{100}=0.62$

The mean of this binomial distribution will be :-

$\mu=np\\\\\mu=(134)(0.62)=83.08$

Standard deviation:-

$\sigma=\sqrt{np(1-p)}\\\\\Rightarrow\sigma=\sqrt{134(0.62)(0.38)}\approx5.6$

Now, the number of seats should be in the non-smoking area in order to be very sure of having enough seating there :-

$\mu+3\sigma=83.08+3(5.6)=99.88\approx100$
