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.

Estimate 58% of 112 using benchmark percents. Explain your answer.
vitfil [10]

Answer:

64.96

Step-by-step explanation:

The most common benchmark percents are 0\% , 10\% , 25\% , 50\% , 75\% and 100\%

We are given 58\% which is closest to 50\%.

Now we calculate 50\% \ of \ 112 which is equal to 56.

We are left with 8\% more to add.

We can say 1\% \ of \ 112 \ is\ 1.12

Therefore 8\% \ of \ 112 \ would \ be \ 1.12\times8=8.96

Now add the two.

56+8.96= 64.96

Thus 64.96 is the answer.

Answer:

As the slope is -2, so the rate of change of the function is:

  • rate of change of function = -2

Step-by-step explanation:

The slope is basically the rate of change of a function.

Let us take the two points from the graph

  • (0, 5)
  • (4, -3)

Taking the slope between two points to determine the rate of change of a function

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(0,\:5\right),\:\left(x_2,\:y_2\right)=\left(4,\:-3\right)

m=-2

As the slope is -2, so the rate of change of the function is:

  • rate of change of function = -2

How do u solve x-y=3<br> 6x+4y=13
earnstyle [38]
X - y = 3
6x + 4y = 13

x = y + 3

6(y + 3) + 4y = 13
6y + 18 + 4y = 13
10y = 13 - 18
10y = - 5
y = - 5/10
y = - 1/2

x = - 1/2 + 3
x = - 1/2 + 6/2
x = 5/2
