The VIX index measures the implied volatility of options on the S&P 500 index. On October 3, 2018 the VIX closed around 11.6 points and on October 4, 2018 it peaked at around 15.7 points. How might this change affect an investor’s saving behaviour?

binary calculations
- Given the following assembly code complete each of the binary calculations by hand. Indicate the resulting value as a signed integer, the overflow flag and whether the result is valid as a signed integer.
mov al, 107 add al, 21
mov bl, -30 add bl, -98
(2) Write an assembly program that contains the following integer definitions:
val1: an 8-bit integer initialized to 23
val2: a 32-bit signed integer initialized to -117
val3: a 16-bit signed integer initialized to 62
The program should perform the calculation ((val3 – 1) – val2) – (val1 + 5) and save the result in a memory location named val4. You need only show the .code and .data segments of the code.
3.
(3) Write an assembly program that subtracts 5 from every value in an array. For example, if the array was (1,2,3,4,5) it should be changed to (-4,-3,-2,-1,0). Make the program as flexible as possible if the array size and type should be changed in the future.
You need only show the .code and .data segments of the code. a) Using indirect addressing.
b) Using indexed addressing
The “pert” model
the “pert” model A=Pert can be used to model exponential growth. If we
let t=0 mean September 2020, there were approximately 3,098 new covid cases in the U.S. at t=0. In October, t=1, there were approximately 4,053 new covid cases.
a) Substitute this data into the “pert” model to find P and r.
b) Use the resulting “pert” model to predict the number of new covid cases in December 2020
