Hi there there's several ways this could be proven one way us to consider the allied angle theory where two angles formed between parallel lines are supplementary which in this case can be proven by
2(45)+90=180⁰ ✔
or 3(45)+45=180⁰✔
this would not be the case if it wasn't parallel
Consequently, you can also use the alternate angle theory where you essentially extend one of the lines and you'll see two equal alternate angles
Answer:
a. 9%
b. 0.01445
c. 12.02%
Step-by-step explanation:
n = 5 years
Return rates = 14%, –9%, 16%, 21%, and 3%
a. Arithmetic average return

b. Historical variance (to 5 decimal places)

c. Standard deviation.

Well there’s two sides of a coin
so divide 58 by 2 to get 29
Answer:
4
Step-by-step explanation:
first you simplify, so -1-3=-4.
|-4|
the absolute value of negative four is just four with all signs removed (in this case, negative sign)
