The missing component is a Control Group

Answer:

Control group

Step-by-step explanation:

A control group is necessary in all experiments that require a comparison. A control group and an experimental group are both included in an experiment. These two need to be identical in every way with the exception of the fact that the experimental group will be subjected to a treatment that is believed to have a particular outcome. In this case, it is difficult to know whether the drink really has the desired effects or not, as we are not aware of the results of a control group.

34 divided 5323 in simple form
joja [24]

The value when 34 is divided by 5323 is 0.00639.

<h3>What is division?</h3>

It should be noted that division simply means the opposite of multiplication. It represents the way numbers are combined in order to make new numbers.

The steps include:

1: Take the dividend's first digit starting from the left in step one. Verify if this digit exceeds or is equal to the divisor.

2. Next, divide it by the divisor, and write the result as the quotient on top.

3. Subtract the outcome from the digit, and then put the difference below.

4: Decrease the dividend's subsequent digit (if present).

5: Carry out Step 4 again.

In this case, 34 divided 5323 will be 0.00639. It should be noted that this illustrates a decimal.

Which of the following are solutions to the graph
jarptica [38.1K]

Answer:

F. \displaystyle (2, 6)

C. \displaystyle (-1, 0)

B. \displaystyle (-2, -2)

Step-by-step explanation:

You first need to find the linear equation<em> </em>[in <em>Slope-Intercept</em><em> </em><em>Form</em><em> </em>of course] of this graph, which is \displaystyle y = 2x + 2.To do this, starting from the y-intercept of \displaystyle (0, 2),you do \displaystyle \frac{rise}{run}by either moving two blocks <em>south</em><em> </em>over one block <em>way</em><em> </em>or two blocks <em>north</em><em> </em>over<em> </em>one block <em>east</em> [<em>west</em><em> </em>and <em>south</em><em> </em>are negatives]. This will give you your <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>] of 2.

* \displaystyle y = mx + b → Slope-Intercept Formula
