A survey of a class of 23 third-graders showed their favorite school lunch. Here is a table of the data. School Lunch Pizza Spaghetti Chicken Nuggets Hamburger Sandwich Students 6 5 2 4 6 Mica created a bar graph to assist in analyzing the data set. Bar graph with title Favourite School Lunch and x-axis with values of Pizza, Spaghetti, Chicken Nuggets, Hamburger, and Sandwich and y-axis labeled Students with values 0 to 7. Pizza bar going up to 6, Spaghetti bar going up to 4, Chicken Nuggets bar going up to 2, Hamburger bar going up to 5, and Sandwich bar going up to 6. Part A: Did Mica create the bar graph correctly? Why or why not? (6 points) Part B: Which type of display would be best to analyze these data? Explain your choice. (4 points)

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

welcome ; )

step-by-step explanation:

hello umm i don't understand your question can you explain it more pls

step-by-step explanation:

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
