Answer:

B) 7

Step-by-step explanation:

7 times 7 is 49 and the square root of 49 is 7. Since 49 is the closest to 50 that's means 7 is your answer cuz the others are either smaller than 50 or way bigger than 50.

Does this make sense lol xD I'm terrible at explaining

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.

The heights of male students are normally distributed with a mean of 160 cm and a standard deviation
kompoz [17]

Answer:

2.28%

Step-by-step explanation:

As this is normally distributed, we can use z scores to find the percentage.

First, find the z-score for 148.

The z-score that you get is:

(148-160)/2=2

As we see that z=2, we can use a calculator or a z-score chart to find the percentage less than a z score of 2.

I used my chart and found: 2.28%
