All you have to do is divide the medium sized jerseys by the total number of jerseys and multiply by 100. 

15/50*100=30%

I would make a proportion for this so (15/50)=(x/100), the x will give you the percentage. Cross multiply to get 50x=1500, then divide both sides by 50, so 30% is your answer because 1500/50=30 so x=30

Cheryl solved a problem: 84 ÷ 0.01 = 8,400.
Alexandra [31]

Answer:

Cheryl is correct.

Step-by-step explanation:

Cheryl solved a problem : 84 ÷ 0.01 = 8,400.

This is absolutely right.

When we divide any whole number with the divisor having decimal, we change the divisor to a whole number before performing the division.

To do this, we multiply both the numbers (divisor and dividend) by the same power of 10, until the divisor is a whole number.

\frac{84\times 10}{0.01\times 10} = \frac{840}{0.1}

to make divisor a whole number we will again multiply both the numbers by 10.

\frac{840\times 10}{0.1\times 10} = \frac{8400}{1} = 8,400

Now answer would be 8400.

Therefore, Cheryl is correct.

In the game of​ roulette, a player can place a ​$4 bet on the number 29 and have a 1/38 probability of winning. If the metal bal
creativ13 [48]

Answer:

The expected value of the game to the player is -$0.2105 and the expected loss if played the game 1000 times is -$210.5.

Step-by-step explanation:

Consider the provided information.

It is given that if ball lands on 29 players will get $140 otherwise casino will takes $4.

The probability of winning is 1/38. So, the probability of loss is 37/38.

Now, find the expected value of the game to the player as shown:

E(x)=(140)\times \frac{1}{38}+(-4)\times \frac{37}{38}

E(x)=\frac{140-148}{38}

E(x)=\frac{-8}{38}=-$0.2105

Hence, the expected value of the game to the player is -$0.2105.

Now find the expect to loss if played the game 1000 times.

1000×(-$0.2105)=-$210.5

Therefore, the expected loss if played the game 1000 times is -$210.5.
