Is 20 ÷ (x + 2) = 5 a equation or expression?

8 0

This is an EQUATION, because it has a left side, a right side, and an = sign separating the two.

An EXPRESSION does not has "sides" and no = sign.

This is an equation because it equals 5.

Expressions have no sign. For ex. 12/ (x+2). That would be simplified.

You could solve this equation too.

The table shows how many males and females attended two different movies. How would you find the joint relative frequency of bei

kirza4 [7]

Answer:

B. Divide 124 by 229.

Step-by-step explanation:

Given the table

$\begin{array}{cccc}&\text{Action}&\text{Drama}&\text{Total}\\ \\\text{Male}&105&124&229\\ \\\text{Female}&99&151&250\\ \\\text{Total}&204&275&479\end{array}$

The <u>joint relative frequency</u> is the ratio of the frequency in a particular category and the total number of data values.

The total number of males $=229$

The number of males that like drama $=124$

So, to find the joint relative frequency of being male and attending a drama movie, you should divide 124 by 229.

David borrowed $30,000 to start a business. Four years later he repaid $1260 in interest. What was the annual rate? Round to two

ollegr [7]

Annual rate = 1.05%

Simple interest formula is I = Prt * 100
Where P is principle, I is interest, r is rate and t is time.

Transpose to make r the subject

Prt * 100 = I
r = I/ Pt * 100

Substitute values into the equation.
Let I = $1260, P = $30,000 and t = 4 years

r = $1260/ $30,000 * 4 * 100
r = 0.0105 * 100
r = 1.05%
