The transformation of figure ABCDE results in figure A”B”C”D”E.

When a figure undergoes reflection across a line, the reflected version is equidistant from that line compared to the original. Initially, ABCDE is reflected over line m to become A'B'C'D'E'. Following this, a rotation of 180 degrees occurs which results in the coordinates swapping places and the sign of the y-coordinate being flipped.

The image A'B'C'D'E' is subjected to a 180-degree rotation leading to the formation of A"B"C"D"E".

The correct answer among the choices is the last option, which describes the transformations as r m 0 Rc180°.

tester [12383]

Answer:

M=2,179.29

The average exceeds the estimate

Her expenses would need to be $1,625.00

Step-by-step explanation:

1.) What is the mean of her friends' personal expenses?

The mean is defined as the average expense value, calculated as follows:

M=\frac{2,800+1,990+2,005+2,400+1,860+2,200+2,000}{7}\\M=2,179.29

2.) Is the average higher or lower than the estimate?

Given the estimate of $2,110, the average is indeed higher than this estimate.

3.)What amount of personal expenses would Ashley need to maintain a combined average of $2,110 with her friends' amounts for that school year?

M= 2,110=\frac{7*2,179.29+x}{8} \\x=2,110*8 - 15,255\\x=1,625

Her needed amount of expenses would be $1,625.00.
