Answer:

A. The lines stay parallel

Step-by-step explanation:

Rigid transformations do not change angle or line relationships. When the parallel lines are rotated they stay parallel. Reflecting them will keep them parallel. If this were not true, then figured with parallel lines like rectangles and squares would change shape when reflected.

16.4.57 Question Help A box contains eighteen $1 bills, ten $5 bills, eight $10 bills, three $20 bills, and one $100 bill You bl

Answer:

$ 7.7

Step-by-step explanation:

Given,

There are 18 $1 bills, ten $5 bills, eight $10 bills, three $20 bills, and one $100 bill,

Total number of bills = 18 + 10 + 8 + 3 + 1 = 40,

$\because \text{Probability}=\frac{\text{Favourable outcomes}}{\text{Total outcomes}}$

Thus,

The probability of $ 1 = $\frac{18}{40}$

The probability of $ 5 = $\frac{10}{40}$

The probability of $ 10 = $\frac{8}{40}$

The probability of $ 20 = $\frac{3}{40}$

The probability of $ 100 = $\frac{1}{40}$

If a bill is selected randomly,

The expected value of the bill

$=\frac{18}{40}\times 1+\frac{10}{40}\times 5+\frac{8}{40}\times 10+\frac{3}{40}\times 20+\frac{1}{40}\times 100$

$=\frac{18+50+80+60+100}{40}$

$=\frac{308}{40}$

= $ 7.7
