Here’s my dilemma, I can accept a $1000 bill or play a game ten times. For each roll of the single die, I win $500 for rolling 1
Aloiza [94]

Answer:

you should accept the $1,000 bill

Step-by-step explanation:

Given the information:

  • $500 for rolling 1 or 2
  • $400 for rolling 3
  • lose $300 for rolling 4,5,6

P (rolling 1 or 2) = 1/6 + 1/6 = 2/6 = 1/3

P (rolling a 3) = 1/6

P (rolling 4 or 5 or 6) = 3/6 = 1/2

Hence, the expected value for 1 time is:

E = (1/3)*500 + (1/6)*400 - (1/2)*300

E = $166 + $66 - $150

E = $82

Expected value is linear so if you roll the die 10 times, expected value is: 10*82 = $820

The expected value is $82, meaning you should accept the $1,000 bill

Find the volume of this 1/4 cylinder after removing the inner part​
denpristay [2]

28-21=7

thickness = 2x7=14

volume =  \frac{1}{4} \pi \times h( {ro}^{2}  -  {ri}^{2} ) \\ =  \frac{1}{4}  \times 3.14 \times 14( {35}^{2}  -  {21}^{2} ) = 8620.276

Number has more than two factors
VMariaS [17]
I'm going to assume that you are asking how a number can have two factors.
So, a factor is an integer (non-fractional/decimal number) you multiply by another integer to get the actual number.

Well, let's look at the number 4. The number four has the following factors:
1, 2, 4
In a 'rainbow' style, you match the two outer numbers, then the two next inner numbers, and so on.
Because the number '2' is the one in the center and there is no other number to multiply it by, it must multiply by itself to reach the number 4.
Well, you must have two numbers to actually multiply together, so every number has two factors: 1, and itself (except for 0). 
I hope this helps, and good luck :)

Please help really need to pass

First add 5 to right side
\frac{x}{7} = -4+5 = 1
Next , to cancel the 7, you need to multiply by 7 on both sides
x = 1*7 = 7
