For this case we have to, by definition:

A number is rational when it can be represented as the quotient of two integers. Example:

$0.3 = \frac {3} {10}$ is a rational number

On the other hand, the irrational numbers are those that can not be written as quotients of integers. They are characterized because their decimal representation is infinite and non-periodic. Example:

$\sqrt {2}$

We have: 291.87

This number has a finite decimal expansion. Then it is rational.

Answer:

Rational

An investment of $5,000 is made at a simple annual interest rate of 3%. How much additional money must be invested at a simple a

liubo4ka [24]

Answer: Additional money is $6250.

Step-by-step explanation:

Since we have given that

Amount of investment = $5000

Rate of simple interest = 3%

Let the additional amount of investment be 'x'.

Rate of simple interest = 3.9%

Total annual interest rate on total investment = 3.5%

So, According to question, it would be

$5000\times 0.03+x\times 0.039=(5000+x)\times 0.035\\\\150+0.039x=175+0.035x\\\\0.039x-0.035x=175-150\\\\0.004x=25\\\\x=\dfrac{25}{0.004}\\\\x=\$6250$

Hence, Additional money is $6250.

Male and female high school students reported how many hours they worked each week in summer jobs. The data is represented in th

kiruha [24]

The biggest key here is identifying outliers. Outliers can pull measures of center either up or down drastically.Notice how the males have a VERY low outlier. This will pull the mean down severely and create a much larger range, or spread.The females have a median of about 12 hours, but have an upper extreme of 19, which compareatively is very high. This creates a larger range as well.
