Yes, the smaller the standard deviation the closer the results are clustered around the mean.

Standard deviations measure the spread of the values in a data set. The more spread out the values, the higher the standard deviation.

You roll a die. If an odd number comes up, you lose. If you get a 6, you win $60. If it is aneven number other than 6, you get t
vitfil [10]

Answer:

Step-by-step explanation:

Given that if an odd number comes up, you lose.

i.e. P(losing) = P(1,3,5) = \frac{1}{2}

P(win 60) = P(6) =\frac{1}{6} \\

If you get 2 or 4 you roll again

Thus rolling again prob = \frac{2}{6} =\frac{1}{3}

After rolling II time, if get 6, win otherwise lose.

Thus winning amounts A canbe

0     36   60

P(0) = \frac{1}{2}+\frac{1}{3} (\frac{5}{6})=\frac{7}{9}  \\P(36) = \frac{1}{3} (\frac{1}{6})=\frac{1}{18}\\P(60) =\frac{1}{6}

This is a genuine pdf since prob >0 and total prob = 1.

b)Expected gain = sum of gain * prob = \frac{7}{9} (0)+\frac{1}{18} (36)+\frac{1}{6} (60)\\=12

Thus I would be willing to pay an amount atmost 12 dollars.

Which ordered pair is a solution of the system of a linear equation below? Y= 1/4x +2 y= x-1
Tanya [424]

Answer:  x = 4, y = 3

<u>Step-by-step explanation:</u>

y=\dfrac{1}{4}x+2    and      y=x-1

Using substitution method we get:

x-1=\dfrac{1}{4}x+2\\\\\text{subtract}\ \dfrac{1}{4}x\ \text{from both sides}\rightarrow \dfrac{3}{4}x-1=2\\\\\text{add 1 to both sides}\rightarrow \dfrac{3}{4}x=3\\\\\text{multiply both sides by 4}\rightarrow 3x=12\\\\\text{divide both sides by 3}\rightarrow x=4\\\\\text{Insert x = 4 into one of the original equations to solve for y:}\\y=x-1\\y =(4)-1\\y=3
