Answer:

~3.547%

Step-by-step explanation:

Use the Binomial Probability Distribution:

P(X=R) = nCr*p^r*q^(n-r)

This equals:

30C20*(.8)^20*(.2)^10

Which equals 0.03547089295...

Help me find the slope

shusha [124]

Answer:

-3/2

Step-by-step explanation:

Slope is defined as $\frac{rise}{run}$ ,

So the line goes down 6 instead of rising, making the rise negative: -6

The line goes over 4, making the run: 4

So -6/4 or -3/2

What's the answer? pls help

Answer: -2

I'm not so sure what it means by slope, but because I saw a pattern between x and y (it decreases by 2 every x value and decreases by 4 every TWO x values) values so I would pick -2. BUT I don't know if the answer is -4.
