Marina CMI [18]

Answer:

G

Step-by-step explanation:

From the box plots given, the options that seem very much on support of the information given in the box plot is option G.

Median number in a box plot is the number at the point where the vertical line divides the box.

The median for Thin Crust is about 55 while the median for Thick Crust is above 55.

Therefore we can conclude that:

"The median number of orders for thick crust pizzas is larger than the median median number of orders for thin crust".

The scatter plot shows the profit by the month for a new company during its first year of operation. Which equation most closely
kondor19780726 [428]

The equation most closely models the line of best fit for the scatter plot is y = 2.5x

<h3>Equation of a line</h3>

A line is the distance between two points. The equation of a line in point-slope form is given as y =mx + b

  • m is the slope
  • b is the intercept


Using the coordinate points on the line (3, 5000) and (9, 20000)

Get the slope

Slope = 20000-5000/9-3
Slope = 15000/6 = 2500

Determine the y-intercept

5000 = 2500(3) + b

b = 5000 - 7500
b = -2500

Determine the equation

y = 2.5x - 2.5

Hence the equation most closely models the line of best fit for the scatter plot is y = 2.5x
