Afigure skater needs a total score of at least 90 to move on to the next round. the total score is the average of four judges’ scores. the first three judges’ scores were 83, 88, and 92. the figure skater made it to the next round.

what is the minimum score the fourth judge could have given?

97

Step-by-step explanation:

It is given that a figure skater needs a total score of at least 90 to move on to the next round.

The first three judges’ scores were 83, 88, and 92.

Let x be the score given by fourth judge.

Formula for average:

where, n is the number of observations.

Average of four judges is

Average score must be at least 90.

Multiply both sides by 4.

Subtract both sides by 263.

Therefore, the minimum score the fourth judge could have given is 97.

450

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'.
