Question 2: What are the type and value of each of the expressions below?
int [] numbers = { 3, 6, 15, 22, 100, 0 };
double [] decimals = { 3.5, 4.5, 2.0, 2.0, 2.0 };
String [] words = {"alpha", "beta", "gamma"};
numbers[3] + numbers[2]
decimals[2] - decimals[0] + numbers[4]
words[1].charAt( numbers [0] )

Compile the following C code to MIPS assembly.
a. Assume that i and j are stored in register $s1 and $s2, respectively. i = i – 2 + j;
b. Assume base address of Array B and the variable i are stored in registers $s3 and $s1, respectively. B[1] = (B[0] x 4) - I;
Explain each step in detail!
my professor has the following answer: 1) addi $t0, $s1, -2 add $s1, $$t0, $s2
2) lw $t0, 0 ($s3) #load B[0] into a register sll $t0, $t0, 2 #shift left logical A[2] x 4 #(may have several different ways) sub $t0, $t0, $s1 # (B[0] x 4) - i sw $t0, 4($s0)
Can you explain in detail why?

Two different leasing options are listed for a truck (worth $27,995 new). How much more must be paid in monthly fees over the full 4 years to take option 2 (instead of option 1)? What is that extra money getting you?
Option 1: Take out a 4-year lease. That is, drive the same car for 4 years paying a monthly fee of $247.28, then turn the car in.
Option 2: Take out two consecutive 2-year leases. That is, after 2 years, turn in the car and lease a new Wrangler for another 2 years. The lease payments would be $257.69 per month.
If you don’t lease at all but take out a 4-year loan at 4.2% interest compounded monthly to buy the car, should the monthly payments be more or less than option A? Why? What will your monthly loan payment be?

1. A prison administrator is interested in examining the relationships between the type of prison security (maximum, medium, and minimum) and the number of previous offenses committed by an inmate. He believes that maximum security prisons have inmates with many prior offenses, medium security with not so many offenses, and minimum security with almost no prior offenses. He randomly selects eight new inmates from each of the three security levels and compares the number of offenses for which they have ever been charged.
a) What is the independent variable?
b) What is the dependent variable?
c) What is the null hypothesis?
d) What is the research hypothesis?
e) Interpret the results.

Please help me super confused on this problem
In: Operations Management
Many regions in North and South Carolina and Georgia have experienced rapid population growth over the last 10 years. It is expected that the growth will continue over the next 10 years. This has motivated many of the large grocery store chains to build new stores in the region. The Kelley’s Super Grocery Stores Inc. chain is no exception. The director of planning for Kelley’s Super Grocery Stores wants to study adding more stores in this region. He believes there are two main factors that indicate the amount families spend on groceries. The first is their income and the other is the number of people in the family. The director gathered the following sample information.
