miskamm [114]

Answer:

Step-by-step explanation:

2p/2 = 2x+7

1) 2x+7 -x - 5 =

width = x + 2

2) 2p/2 = 21 in

x + 5 + x + 2 = 21

2x = 14

x = 7

lenght = 7 + 5 = 12 in

width = 7 + 2 = 9 in

3 )

A = (x+5)(x+2)

A = 12 x 9 = 108

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 :-

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