Answer:

The formula for the probability distribution is:

P(X = n) = q^(n - 1)p

= [0.2^(n - 1)]0.8

Step-by-step explanation:

This is a geometric probability distribution.

The probability of success p = 80% = 0.8

The probability of failure is q = 1 - p = 0.2

The formula is:

P(X = n) = q^(n - 1)p

= [0.2^(n - 1)]0.8

Solve -2.5n + 8.7 &gt; 5.45.
AlexFokin [52]
A. n<1.3

-2.5n+8.7>5.45
subtract 8.7 from both sides
-2.5n>-3.25
divide -2.5 from both sides 
(since you divided by a negative you flip the sign!!)
n<1.3

Use the substitution method to solve the system of equations choose the correct ordered pair
Gekata [30.6K]

Answer:

C. (4,28)

Step-by-step explanation:

The substitution method requires you to input a specified number in place of a variable. In this case, the variable 'x' should be replaced by the number 4. Using the order of operations, we know that multiplication should be applied before subtraction. When we replace 'x' with 4, we get the equation 'y=8(4)-4'. Multiplying 8 and 4 gives us 32. If we subtract 4 from 32, we get 28. The answer ends up being 'y=28'.

That is the first part of our solution. What we are actually looking for is an ordered pair. We know ordered pairs are written in the form (x, y). First, we need to find the 'x'. The 'x' has been given to us from the beginning, it is 4. Next is the 'y'. This is what we needed to find using substitution. We ultimately concluded that the 'y' is equivalent to 28. Therefore our ordered pair is (4, 28), the letter choice C.

I hope this helped you and that I clearly elaborated on the answer choice.

What is the area of the hexagon below?
sergejj [24]

Answer:

14m^2

Step-by-step explanation:

To find the area of this hexagon, you should separate this shape into 2 other shapes.

You can see that there is a parallelogram, and a rectangle shape within this hexagon, so you can find the area of these 2 shapes and later on, just add it.

The area of this rectangle is...

width✖️height: 6✖️2=12

The area of this parallologram is...

base✖️height: 6✖️2=12

12+12=14m^2
