Answer:

<em><u>y = d + a · cos(bx - c) ⇒ y = -4cos(4/3x)</u></em>

  • a = -4
  • b = 4/3
  • c = 0
  • d = 0

Amplitude = |a| = |-4| = 4

Period = \frac{2\pi }{b} =\frac{2\pi }{\frac{4}{3} } =2\pi *\frac{3}{4} =\frac{3}{2} \pi

A bet on "black" in Roulette has a probability of 18/38 of winning. If you win, you double your money. You can bet anywhere from
abruzzese [7]

Answer:

Check the explanation

Step-by-step explanation:

let the money on bet is X.

probability of winning =18/38=9/19

probability of losing =(1-9/19)=10/19

expected outcome =\tiny \sumprobability *return   =(

Expected value of return after one bet is =(9/19*x)-(10/19*x)=-1x/19

it is negative which is obvious cause casinos are there to earn money.

a) Our best strategy in this case as probability of winning is near by 50 %, we should place a bet of 1 $ each,and when we lose one bet consecutively we should bet twice the amount..

Cause two consecutive losses on black has less probability.

c) In case we have to reach 30 $ we have to use the same strategy as above.

Aleks04 [339]

Answer:

<h2>$1380.2</h2>

Step-by-step explanation:

Step one:

given data

weekly earnings= $375

Commission is 4% of sales.= 0.4

supposing sale is x, and the total earning is y

the expression for the total earning will be

y=375+0.4x

Step two:

for x= 2513, y will be

y=375+0.4(2513)

y=375+1005.2

y=1380.2

<em><u>Hence  her total earnings for the week will be $1380.2</u></em>
