I want to know if mammals usually have more
DENIUS [597]

The graph that would allow the comparison between the median number of teeth for mammals and reptiles easily is a Box Plot.

<h3>Median</h3>

The median of a set of data is the midpoint of values in a data set. It shows the value that divides the data set into two halves.

<h3>Box plot</h3>
  • A box plot is a type of graph used in data analysis to visualize the distribution of numerical data and skewness by displaying the data quartiles and averages.

Box plots are also known as box and whisker plot.

  • Box plots are used to compare visually differences among different samples or groups such medians, ranges, and outliers.

Therefore, the graph that would allow the comparison between the median number of teeth for mammals and reptiles easily is a Box Plot.

What is the solution for 2x -4= -8
scoray [572]

Answer:

  x = 48

Step-by-step explanation:

  3x +  9 = 153

 

subtract 9 from both sides               -9       -9

 

                                                     3x = 144

 

divide both sides by 3                    3x/3 = 144/3

2x + (x + 9) = 153

 

2(48) + (48 + 9) = 153

 

96 + 57 = 153

 

153 = 153
