Pythagoras theorem:
hypotenuse²=leg₁²+leg₂²

Data:
leg₁=8
leg₂=15
hypotenuse=s

hypotenuse²=(8)²+(15)²
hypotenuse²=64+225
hypotenuse²=289
hypotenuse=√289
hypotenuse=17

Answer: s=17

By Pythagoras' Theorem.

s² = 8² + 15²

s²= 64 + 225

s² = 289

s = √289

s = 17

<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 .

In an experiment, some diseased mice were randomly divided into two groups. One group was given an experimental drug, and one wa
damaskus [11]

Answer:

D)Yes, because the difference in the means in the actual experiment was more than two standard deviations from 0.

Step-by-step explanation:

We will test the hypothesis on the difference between means.

We have a sample 1 with mean M1=18.2 (drug group) and a sample 2 with mean M2=15.9 (no-drug group).

Then, the difference between means is:

M_d=M_1-M_2=18.2-15.9=2.3

If the standard deviation of the differences of the sample means of the two groups was 1.1 days, the t-statistic can be calculated as:

t=\dfrac{M_d-(\mu_1-\mu_2)}{s_{M_d}}=\dfrac{2.3-(0)}{1.1}=2.09

The critical value for a two tailed test with confidence of 95% (level of significance of 0.05) is t=z=1.96, assuming a large sample.

This is approximately 2 standards deviation (z=2).

The test statistict=2.09 is bigger than the critical value and lies in the rejection region, so the effect is significant. The null hypothesis would be rejected: the difference between means is significant.
