Which histogram is an accurate representation of the data?
a.
A histogram has frequency on the x-axis, and number of hours on the y-axis. 0 to 9 is 8, 10 to 19 is 2, 20 to 29 is 10, 30 to 39 is 12, 40 to 49 is 4, 50 to 59 is 2.
b.
A histogram has number of hours on the x-axis, and frequency on the y-axis. 0 to 9 is 1, 10 to 19 is 6, 20 to 29 is 15, 30 to 39 is 12, 40 to 49 is 2, 50 to 59 is 4.
c.
A histogram has number of hours on the x-axis, and frequency on the y-axis. 0 to 9 is 8, 10 to 19 is 3, 20 to 29 is 10, 30 to 39 is 12, 40 to 49 is 4, 50 to 59 is 1.
d.
A histogram has frequency on the x-axis, and number of hours on the y-axis. 0 to 9 is 1, 10 to 19 is 6, 20 to 29 is 15, 30 to 39 is 12, 40 to 49 is 2, 50 to 59 is 4.

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'.

i dont know

step-by-step explanation:

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
