Answer:

Control Group.

Step-by-step explanation:

A control group, in research, is a group that is not experimented by the researchers in an experiment. A control group is the opposite of an experimental group, on which the independent variable is performed. In other words, an independent variable is held on 'control' in control group.

<u>In the given scenario, the experiment is being performed to test a new physical therapy. To do so, the researchers divided the group in three groups, in which, one group did not receive any treatment; the treatment is held on 'control' in this group.</u>

So, according to the definition provided, the group that did not receive the treatment will be called a control group, thus the correct answer.

Answer:

$= 100$

Step-by-step explanation:

TSA of brick → 2(L×b+b×h+h×l)

$= 2(22.5× 10 + 10 \times 7.5 +7.5 \times 22.5)$

$= 2 (225 +75 + 168.75) cm²$

$=2 ( 468.75) cm ²$

$= 937.5cm²$

$= \frac{937.5 {cm}^{2} }{100 \times 100}$ $=0.09375 m²$

Therefore, Required number of Bricks-

$= \frac{9.375 {cm}^{2} \times 100}{0.09375 \: {cm}^{2} }$

$= 100$

Hence,The required Number of Bricks = 100 respectively.

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, $3*10=30$ .
