never [62]

Answer:

P(n>55)=0.1357

Step-by-step explanation:

From the question we are told that:

Sample size n=100

Sample space n'=36

Generally the equation for the mean number of times odds appears is mathematically given by

\=x_o=hp

\=x_o=100*0.5

\=x_o=50

Generally the equation for standard deviation is mathematically given by

\sigma=(hp(1-p))^{1/2}\\\sigma=(50(0.5))^{1/2}

\sigma=5

Therefore probability to make wrong decision P(n>55)

P(n>55)=1-P(z55)=1-P(z55)=1-0.86

P(n>55)=0.1357

What is 0.95 rounded to the nearest hundread?
sasho [114]

0.95 rounded to the nearest hundredth (I assume that's what you mean) would still be 0.95. Since I saw your other question, I think you're looking for 0.095 rounded to the nearest hundredth, which is 0.10.

What is the slope OF THE GRAPH, not what is A slope, what is THE slope
Oksanka [162]

Answer:

-3/1

Step-by-step explanation:

The slope can be found by putting the rise over the run.  

Pick 2 points on the graph that intercept the line.

I'll pick (0,2), and (1,-1)

Look at the rise.(How many places it goes up or down)

The rise vertical distance(rise), between the two points is -3.

Now look at the run(the horizontal distance.)  It's 1.

Rise/Run =  -3/1  AKA -3
