Use the following information for the question below: You conduct a clinical trial to test whether a new drug relieves the sympt

oms of arthritis better than a placebo. You have four groups of participants, all of whom have moderately painful arthritis (rated 7 on a scale of 1 to 10). Each group receives a daily pill as follows: group 1-placebo; group 2-15 mg; group 3-25 mg; group 4-50 mg. At the end of 2 weeks, participants in each group are asked to rate their pain on a scale of 1 to 10. What is the independent variable in this experiment?

Answer:

The independent variable is the dose of the drug given to each participant.

Step-by-step explanation:

In the current experiment each patient's initial level of pain is going to be the <em>initial condition </em>for the experiment. We're going to measure the final level of pain and we'll try to find any correlation between the variation in the level of pain and the number of milligrams of the drug given to each patient, so that last one (the dose of the drug) is the independent variable because is the one variable that we're going to modify in order to see the effect that it has in the final measurement.

\bold{\huge{\underline{ Solution }}}

<h3><u>Analysis </u><u>of </u><u>graph </u><u>:</u><u>-</u></h3>

We have given one graph which is plot between distance and time. where time is in minutes and distance is in seconds.

<u>According </u><u>to </u><u>the </u><u>graph </u>

  • For the first 5 minute ( O to A) , The distance is continously increasing 2m / per minute .
  • For the 5 minute that is from 5 minute to 13 minute ( A to B) both marellize and her dog wally moving with the constant speed .
  • For next 3 minutes that is from 10 minutes to 13 minutes ( B to C) , The distance is continously decreasing with time .
  • For next 3 minutes that is from 13 to 16 minutes ( C to D) , Again they moved with constant speed .
  • For next 6 minute that is from 16 to 21 minutes ( D to E) . Again, There distance is increasing with time .
  • Again For next 4 minutes that is 21 to 25 minutes , they are moving with constant velocity .

<h3><u>Let's </u><u>Begin </u><u>:</u><u>-</u></h3>

1) Between O and A

  • The marellize and wally when moving between O to A , The distance is constantly increasing with time.
  • The graph is Straight line

2) Between A and B

  • The marellize and wally when moving between A to B, The distance remains the same with time that is they moving with constant speed.
  • The graph is constant or steady

3) Between B to C

  • The marellize and wally when moving between B to C, The distance is constantly decreasing with time .
  • The graph is straight line but it follows decreasing function .

4) For covering the First 6 km ,

<u>According </u><u>to </u><u>the </u><u>graph</u><u>, </u>

  • For covering first 6 km, They took 3 minutes.

5) No, Marellize and wally walk does not from where they have started.

<u>According </u><u>to </u><u>the </u><u>graph </u>

  • It is end at 5 m instead of 0m .

What is the volume of this square pyramid?
tatuchka [14]

Answer: 1296 cm³

Step-by-step explanation:

Since, the volume of a square pyramid is,

V = \frac{a^2h}{3}

Where a = side of the square base,

h = height of the pyramid,

By the given diagram,

a = 18 cm,

h = 12 cm,

Hence, the volume of the given pyramid,

V = \frac{18^2\times 12}{3}

= \frac{324\times 12}{3}

=\frac{3888}{3}

=1296 cube cm.

⇒ First option is correct.
