The ratio of the length to the width of a rectangle is 5:4. The length of the rectangle is 60 inches. What is the width?

Firlakuza [10]

$\huge\boxed{\text{48 inches}}$

We know that $\frac{\text{length}}{\text{width}} = \frac{60}{\text{width}} = \frac{5}{4}$ .

Solve using cross multiplication of the last two fractions. I will use $w$ to represent the width of the rectangle. $60*4=w*5$

Multiply. $240=5w$

Divide both sides of the equation by $5$ . $\boxed{48}=w$

The numbers of regular season wins for 10 football teams in a given season are given below. Determine the range, mean, variance,

tensa zangetsu [6.8K]

We have the following data set:

2,7,15,3,12,9,15,8,3,10

The range is the difference between the highest and lowest values in the set, to find the range, order the data set from least to greatest.

2,3,3,7,8,9,10,12,15,15

Then,

$\begin{gathered} \text{Range}=15-2 \\ \text{Range}=13 \end{gathered}$

Mean is represented by the following expression:

$\text{Mean}=\frac{\text{Sum of all data points}}{Number\text{ of data po}ints}$ $\text{Mean}=\frac{84}{10}=8.4$

Population variance formula looks like this:

$\begin{gathered} \sigma^2=\frac{\sum^{}_{}(x-\mu)^2}{N} \\ \text{where,} \\ \sigma^2=\text{population variance} \\ \sum ^{}_{}=addition\text{ of} \\ x=\text{each value} \\ \mu=population\text{ mean} \\ N=\text{ number of values in the population} \end{gathered}$

Then, substituting:
