Cassandra and Yvette each have a calculator. Yvette starts at a 100 and subtracts 7 each time. Isandro starts at zero and adds 3

34kurt

This can be be solved the following way:
Yvette starts at 100 and subtracts 7 k times, as for Cassandra (or Isandro, the question is not clear on this) she starts at 0 and presses adds 3 k times. This leads to the following equation:
$100-7k=3k$
$100=10k
\\
10=k$
So for k=10 they will both display the same number.
We can now either choose the viewpoint of Cassandra or Yvette:
If we chose Yvette then we'll have $100-7*10=30$ and for Cassandra we have, $3*10=30$ .

Answer:

Assignments finished = 7

Step-by-step explanation:

Given that:

Time taken for one assignment = 20 minutes

Time spent on working = 2 hours 20 minutes

2 hours = 120 minutes

Time spent on working = 120 + 20 = 140 minutes

Number of assignments = $\frac{Total\ time\ spent}{Time\ on\ one\ assignment}$

Number of assignments = $\frac{140}{20}$

Number of assignments = 7

Hence,

Assignments finished = 7

Answer:

Stratified sampling

Step-by-step explanation:

In the question, students are selected from subgroups of Sophomore, Junior, and Senior classes.

We are told that 49, 34, and 48 students are selected from the Sophomore, Junior, and Senior classes with 496, 348, and 481 students respectively.

This means that the sample numbers of 49, 34 and 48 students were selected in proportion to the subgroup sizes of 496, 348, and 481 students respectively.

Thus, due to the fact that subgroups were selected & that sample number of students were also selected in proportion to their respective subgroup sizes, this is therefore a stratified sampling.
