Answer:

P(X = 0) = 0.25

P(X = 1) = 0.75

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The probability distribution of X.

3 red balls out of 4, one picked, so we can have either 0 red balls or 1 red ball. The probability disitribution is the probability of each outcome.

P(X = 0) = \frac{1}{4} = 0.25

P(X = 1) = \frac{3}{4} = 0.75

How many is?<br> with procedure and testing<br> PLEASE<br><br> -4x + 13 = 6x - 7
slamgirl [31]
To solve for X you must get x by itself so let's get started
-4x+13=6x-7
subtract 13 from both sides
-4x=6x-20
subtract 6x from both sides
-10x=-20
divide both sides by -10
x=2

to check if this is correct plug in x into original equation
-4 (2)+13=6 (2)-7
-8+13=12-7
5=5
answer x=2 holds true :)

Answer:

Step-by-step explanation:

Area of the field = pi * r^2

r = 230/2 = 115

Area of the field = 3.14 * 115^2 = 41526.5 square feet.

Number of bags = 41526.5/400 = 103.82 bags

In the above figure, m AOC=26 and m BOD= (2x+39). If AOC and BOD are vertical angles whats the value if x?
Reika [66]

If AOC and BOD are vertical angles, the value of x is x = -6.5

<h3>How to determine the value of x?</h3>

The angles are given as:

m AOC = 26

m BOD = (2x+39).

From the question, we have

AOC and BOD are vertical angles

Vertical angles are equal.

So, we have:

AOC = BOD

Substitute the known values in the above equation

2x + 39 = 26

Subtract 39 from both sides

2x = -13

Divide bot sides by 2

x = -6.5

Hence, if AOC and BOD are vertical angles, the value of x is x = -6.5
