Answer:
13.5
Step-by-step explanation:
There are 20 nickels and 10 pennies.
20 cents x 5 is $1.00 and 10 cents x 1 is 10 cents so it is $1.10 because a nickel is 5 cents so 20x5 is a dollar and a penny is worth 1 cent and 10 pennies is 10 cents so $1.00+$0.10=$1.10 brainliest is appreciated! :)
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.

Answer:
Step-by-step explanation:
Equation of blue line:
blue line is parallel to y-axis
⇒ x = 5
Equation of green line:
Green line is parallel to x-axis.
y = 2
Equation of red line:
At y-intercept x = 0. Point on red line is (0,5)
So, y-intercept = 5
y = mx + b Here, m is slope any b is y-intercept.
y = mx + 5
Now, choose any other point in red line. ((1,7)
Substitute this value in the above equation and we can find m
7 = m*1 + 5
7 - 5 = m
m = 2
y = 2x + 5
Equation of black line:
Black line and red line are parallel and so, they have same slope.
y = 2x + b
y-intercept (0,-6) ; b = -6
y = 2x - 6
