+ is a girl and = is a boy.
So let's say the line starts with a boy and ends with a girl, there's one way.
= + = + = +
Now, let's reverse it, to where it starts with a girl and ends with a boy.
+ = + = + = +
There are two ways to arrange the line if there must be alternating girls and boys
Answer:
Third choice, 3/4
Step-by-step explanation:
Add all the cubes together, 12 + 5 + 3 = 20
There's a 12/20, which is 3/5, chance you'll get a green cube
5/20, which is 1/4, chance you'll get a blue cube
And there's a 3/20 chance you'll get a yellow cube
The probability of not getting a blue cube is 12/20 + 3/20 = 15/20 = 3/4
Answer:
B contains a table with a logical series of statements and reasons that reach a conclusion.
Step-by-step explanation:
A two-column proof
uses a visual representation of the logical flow of steps needed to reach a conclusion.
contains a table with a logical series of statements and reasons that reach a conclusion.
contains a set of sentences explaining the steps needed to reach a conclusion.
uses inductive reasoning to prove a statement.
1/2(4x-5) + 5/2 = 10
Use the distributive property:
2x - 5/2 + 5/2 = 10
Use addition property:
2x = 10
Divide both sides by 2:
x = 10/2
x = 5
