<em>Answer:</em>
The new weight-loss supplement was less effective on females in the study. That is because only 65% of them lost weight after two weeks, whereas 74% of the males lost weight after two weeks.
<em>Explanation:</em>
37 out of 50 males lost weight after two weeks, so 74% of males lost weight ( (37 · 2)/(50 · 2) ). 13 out of 20 females lost weight after two weeks, so 65% of females lost weight ( (13 · 5)/(20 · 5) ). This means the supplement was less effective on females because males had a higher percentage of losing weight.
Hope this helps !! :D

Answer:</h3>
7.838 seconds
<h3>
Explanation:</h3>
- Assuming the sound of sound in seawater is 1531 m/s we can calculate the time taken by the signal to leave the ship and back.
- The depth to the bottom is 6000 meters
- The sound signal will cover the distance twice, to and fro the bottom to the ship.
- Time is calculated by dividing the distance by the velocity or speed.
In this case;
Time = (2× distance) ÷ velocity
= (2×6000) m ÷ 1531 m/s
= 12000 m ÷ 1531 m/s
= 7.838 s
Therefore, it will take 7.838 s for the sound signal to leave the ship and bounce back off and return to the ship.
Answer:
0.0555m converts to 55.5 mm
