It was recommended that students drink 48 or more ounces of water. How
azamat

A histogram is used to show the frequency of data, where the length of the bar represents the frequency.

<em>50 students drank the recommended amount of water.</em>

The recommended amount is given as:

Amount \ge 48

See attachment for histogram.

From the histogram, we have the following observations

  • <em>The lengths of all bars of the histogram are less than 48, except one.</em>
  • <em>The length of the bar above 48 is 50.</em>

<em />

This means that:  50 students drank the recommended amount of water.

<em>Hence, the number of students is 50</em>

What is greater one seventh or one nineth
Anton [14]

Method 1:

Look at the picture.

\dfrac{1}{7} is greater than \dfrac{1}{9}

\boxed{\dfrac{1}{7}>\dfrac{1}{9}}

Method 2:

Find the common denominator:

multiples of 7: 0, 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, ...

multiples of 9: 0, 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, ...

63 = 7 · 9

\dfrac{1}{7}=\dfrac{1\cdot9}{7\cdot9}=\dfrac{9}{63}\\\\\dfrac{1}{9}=\dfrac{1\cdot7}{9\cdot7}=\dfrac{7}{63}

\dfrac{9}{63} > \dfrac{7}{63}

therefore

\dfrac{1}{7} > \dfrac{1}{9}
