Answer:

Control group

Explanation:

In an experiment, the group which receives the treatment (in this case injection of actual drug)  is known as experimental group because the experiment is being conducted on it. While on the other hand the group which do not receive the treatment is known as control group. The results obtained from the experimental group are compared with the control group to determine the effectiveness of the treatment.

Linear equations are used to represent relations that have constant rates

The linear regression equation that models the data in this table is \^y = 2.40476x + 0.33333

<h3>Regression equation using a graphing calculator</h3>

To calculate the regression equation, we make use of a graphing calculator.

Using the graphing calculator, we have the following data:

  • Sum of X = 28
  • Sum of Y = 70
  • Mean X = 3.5
  • Mean Y = 8.75
  • Sum of squares (SSX) = 42
  • Sum of products (SP) = 101
<h3 /><h3>Formulating the regression equation</h3>

The regression equation is represented as:

\^y = b\^x + a

Where:

b = \frac{SP}{SSX} and a = MY - bMX

So, we have:

b = \frac{101}{42}

b = 2.40476

Also, we have:

a = MY - bMX

a= 8.75 - 2.4\times 3.5

a= 0.33333

Hence, the linear regression equation is:

\^y = 2.40476x + 0.33333

maria [59]

Answer:

In grassland ecosystem, first trophic level is the producer. Producers are the organisms which makes their own food, here the producer are grasses. The second trohic level contain herbivores which feed on these grasses. These herbivores are eaten by secondary consumers which belongs to third trophic level and secondary consumers are then eaten by tertiary consumer.

The population of producers are very high so it is placed at the base while tertiary consumer are placed on the top due to low population.
