Answer:

14/45

Step-by-step explanation:

Probability is the likelihood or chance an event will occur.

Probability = Expected number of outcome/Total outcome

Total number of chocolate = Total outcome = 45

Before we can get the probability of a chocolate chosen at random of selecting a walnut, we need to know the number of chocolates that have walnuts.

Number of chocolates that have walnuts = 45-(10+21)

= 45-31

= 14

This means that our expected outcome is 14

Probability of a chocolate chosen at random of selecting a walnut = 14/45

Answer:

\frac{7}{24}

Step-by-step explanation:

A box of Godiva chocolates contains 45 identically wrapped  chocolates. Ten are truffles, 21 have caramel fillings, the rest have walnuts.

Total number of chocolates = 45

total outcomes = 45

10 truffles, 21 caramel

number of walnuts = total chocolates - truffles - caramel

walnuts = 45 - 10 - 21= 14

Probability of selecting walnut = \frac{number of walnut}{total chocolates}

P(walnut) = \frac{14}{45}

A regular polygon has a exterior of 18 degrees. How many sides does it have?
blondinia [14]
The formula of the measurement of an exterior angle of a regular polygon is
β = 360°/n
where β = exterior angle and n = number of sides

Therefore,
n = 360°/β = 360°/18° = 20 sides

What is 3/8 -1/8 plz help me !!!!!
Nuetrik [128]
2/8 is the answer because if you do 3-1 it would equal 2 and then you would put 2 over eight. You can even simplify it to 1/4 because 2 and 8 can both be divided by 2.

Revenue from Monorail Service, Las Vegas In 2005 the Las Vegas monorail charged $3 per ride and had an average ridership of abou
Karolina [17]

Answer:

A)The required linear demand equation ( q ) = -4500p + 41500

B) $4.61

   $95680.55

C) No it would not have been possible by charging a suitable price

Step-by-step explanation:

<u>A)  find the linear demand equation</u>

given two points ; ( 3, 28000 ) and ( 5, 19000 )

slope ( m ) = ( y2 - y1 ) / ( x2 - x1 )

                 = ( 19000 - 28000 ) / ( 5 - 3 )  = -4500

slope intercept is represented as ; y = mx + b

where y( 28000) = -4500(3) + b

  hence b = 41500  

hence ; y = -4500x + 41500

The required linear demand equation ( q ) = -4500p + 41500   ----- ( 1 )

p = price per ride

<u>B ) Determine the price the company should charge to maximize revenue from ridership  and corresponding daily revenue</u>

Total revenue ( R ) = qp

                               = p ( -4500p + 41500 )

  hence R = -4500p^2 + 41500p  ------ ( 2 )

To determine the price that should maximize revenue from ridership we will equate R = -4500p^2 + 41500p  to a quadratic equation R(p) = ap^2 + bp + c

where a = -4500 ,  b = 41500 , c = 0

hence p = -\frac{b}{2a}  = - \frac{41500}{2(-4500)} =  4.61

$4.61 is the price the company should charge to maximize revenue from ridership

corresponding daily revenue = R = -4500p^2 + 41500 p

where p = $4.61

hence R = -4500(4.61 )^2 + 41500(4.61) = $95680.55

C) No it would not have been possible by charging a suitable price
