The text states that the expected value for the Iowa State Lottery is about −46% for the player. What could the state do to incr

ease (or decrease) this expected value? To increase the expected value, the probability of someone winning must decrease. So, if the state took out some possible numbers, the probability (and expected value) of winning would decrease. To decrease the expected value, add more numbers to the lottery number possibilities. To increase the expected value, the state simply needs to hold lottery drawings more often. If there are more chances to win, the expected value will increase. To decrease the expected value, hold the lottery less often. To increase the expected value, the state simply needs to hold lottery drawings less often. If there are fewer chances to win, the expected value will increase. To decrease the expected value, hold the lottery more often. To increase the expected value, the probability of someone winning must increase. So, if the state took out some possible numbers, the probability (and expected value) of winning would increase.

This questions can be answered with a calculator, but I have an impression it is meant to be a mental calculation problem, which can be solved as follows.

We know that 10*10=100, in otherwords, &radic; 100 = 10 which is greater than 9.4247.

We also know that &radic; 108  is greater than &radic; 100 =10

So we can conclude that
&radic; 108 > &radic; 100 = 10  > 9.4247
or simply

&radic; 108 > 9.4247

by the transitive property of logical propositions.

The perimeter of this rectangle is 156 cm.
erastova [34]

Answer:

x = 15

Therefore, the length and width are 31 and 47.

Step-by-step explanation:

Perimeter = (2x + 1) + (2x + 1) + (3x + 2) + (3x + 2) = 156

Simplified,

10x + 6 = 156

Subtract 6 from both sides, then divide by 10.

10x = 150

x = 15

To find the length and width, substitute 15 (the value of x) into the individual equations.

2(15) + 1 = 31

3(15) + 2 = 47
