PLEAS HELPPP A middle school coach wrote down the time, in seconds, of her students’ 100-meter dash as shown in the table.
Student Time -(seconds)
Gary 11.9
Rick 12.3
Phillip 13.5
Jorge 12.0
Robert 12.3
Jeremy 16.0

If the slowest time and the fastest time are removed from the data, how does the new mean compare to the mean of the original data set?

A. The mean would not change as the lowest and greatest values were removed.
B. The mean would increase as there is less variability in the data.
C. The mean would not be comparable as the data sets are different.
D. The mean would decrease as there is less variability in the data.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
