Answer:

42 cents

Step-by-step explanation:

Data provided in the question:

Random variable i.e gain with values 3,2,1,-1.

Now,

The corresponding probabilities will be as follows:

$P(3)=(\frac 16)^{3}$

$P(2)=3\times(\frac 16)^{3}$

$P(1)=3\times(\frac 16)^{3}$

$P(-1)=1-7(\frac 13)^{3}$

Expected gain = $3\times(\frac 16)^{3}+2\times3\times(\frac 16)^{3}+1\times3\times(\frac 16)^{3}-1\times\left(1-7\times(\frac 13)^{3}\right)$

Expected gain = $(\frac 13)^{3}[3+6+3-(0.7407)]$

$=(\frac 16)^{3}[11.2593]=0.4170$

≈ 42 cents

Which of the following is the same as 8.4 × 102 ? A. 84 B. 8,400 C. .84 D. 840

aleksklad [387]

Based on the given answers, do you possibly mean 100 instead of 102?
If so, you would move the decimal point of 8.4 two places to the right, meaning the answer would be letter D. 840.

Look at image.........

iren2701 [21]

Answer:

first of all its not d since the y intercept is negitive

then its not b since its sloping down

so the slop is either 7/5 or 5/7

since rise/run it has to be 7/5

Hope This Helps!!!
