Answer:

Cup 1 acts as a control group.

Step-by-step explanation:

Control group: The group used in the experiment by the researchers in which no change in the variable is done. It is then set as a benchmark for the groups which are being tested.

We are given 4 groups which are being experimented for the flotation of an egg in water.

Since in Cup 1, there is no addition of salt

So, there is no change in the variables.

So, by definition of control group .

So, cup 1 acts as a control group since there is no change in the variable .

Hence, the correct answer is Option 1.

Cup 1 acts as a control group.

Jeff drinks 2/3 of a glass of juice. Write <br> a fraction equivalent to 2/3
Rufina [12.5K]
A fraction that means the same as 2/3 is 4/6.

To find this, you can simply multiple both the numerator and denominator (top and bottom) by any number as long as it's the same number for both top and bottom.
In this case, we used 2 as the number, and multipled it to the top and bottom of 2/3, to get 4/6.

I hope this helps!

The range, a measure of variability, Group of answer choices is the difference between the largest (L) and smallest (S) value in
Vlad [161]

<u>The correct answer is </u><u>all of the above.</u>

Why is the range the most convenient measure of variability?

  • Your data's spread from the lowest to the greatest value in the distribution is indicated by the range.
  • The calculation of this variability index is the simplest.
  • Simply subtract the lowest value from the highest value in the data set to determine the range.

How do you find the range?

  • The difference between the lowest and highest values in a list or set is known as the range.
  • Put all the numbers in order before determining the range. The lowest number should then be subtracted from the highest.
  • The range of the list is provided in the response.
