To simplify this, we first need to distribute the 2 into the parenthesis.

= 2 * x + 2 * 3 - 4

Now, we can simplify:

= 2x + 6 - 4
= 2x + 2

Hope this helps!

Okay, we want to start with having the original expression for the first step.

2(x+3)-4
We can use distributive property to get rid of the parenthesis. So I will be multiplying everything inside the parenthesis by the 2.

2x + 6 - 4
The reason I didn’t multiply the four by two was because the four is outside of the parenthesis. Right now, we can add like terms. Four is basically negative since it has a subtraction sign outside of it and six is positive ( this is the same as doing 6-4, I’m just calling it negative because as you get used to simplifying expressions, you have to think of it that way).

6+(-4)=6-4=2
Now we have all the like terms added, we can find our simplified expression.
2x+2

At a certain airport, 65% of the flights arrive on time. A sample of 10 flights is studied. Find the probability that all 10 of
babunello [35]

Answer:

So, the probability is P=0.0135.

Step-by-step explanation:

We know that at a certain airport, 65% of the flights arrive on time.

We get that p=0.65 and q=1-0.65=0.35.

We have 10 flights, so n=10.

We calculate the probability that all 10 of the flights were on time, so k=10.

We use the formulu:

\boxed{P(X=k)=C^n_k \cdot p^k\cdot q^{n-k}}

we get:

P(X=10)=C^{10}_{10}\cdot 0.65^{10}\cdot 0.35^0\\\\P(X=10)=1\cdot 0.0135\cdot 1\\\\P(X=10)=0.0135\\

So, the probability is P=0.0135.

A regular decagon has 10 sides. How many reflectional symmetries does a regular decagon have?
lina2011 [118]

The rule for regular polygons are very easy. The number of reflectional symmetries is same as the number of sides. Regular polygons have all sides the same length and all angles same. Reflection symmetry means that you can fold the shape along that line and it will match up.

For this question, we want the number of reflectional symmetries of a regular decagon. Decagon is a 10 sided figure. Hence, the number of reflectional symmetries is 10.

There are 5 symmetry lines from one vertex to opposite vertex and 5 more symmetry lines form midpoint of one side to midpoint of opposite side.
