Answer:
The distance 5 miles North-East of the intersection between the car and the truck increasing at 71.06 miles per hour at that moment.
Step-by-step explanation:
Looking at the attached figures, Fig 1 shows the diagram of the car and the truck.
Using Pythagoras theorem on Fig 1a,
The resultant displacement between the car and the truck at that same moment is 5 miles.
From the velocity vector diagram on Fig 2,
The resultant velocity R is given as
Therefore, the distance 5 miles North-East of the intersection between the car and the truck increasing at 71.06 miles per hour at that moment.
First, we should rearrange the first equation to set it equal to y:
-x + 2y = 6
2y = 6 + x
y = 3 + 0.5x
Now, we can plug this into the second equation for y and solve for x:
6y = x + 18
6(3 + 0.5x) = x + 18
18 + 3x = x + 18
3x = x
2x = 0
x = 0
The x-value of the solution is 0.
Answer:
Multiply everything by 15 because when you divide 40 from 600 you get 15. We will only use the 2 numbers on the right of both samples. Then find the total of each row
<u>18 turns into 270| 10 truns into 150 </u>=420
<u>19 turns into 285| 7 turns into 105</u>=390
Headline A: Both samples show that over 300 students want to go after 8 am which makes the headline true.
Headline B: 8:30 is actually the most popular start time because both samples show greater amount of students choose 8:30 as the start time than any other time.
Headline C: This statement is not supported by the data, the data shows that 7:45 am is the second most popular selection.
Headline D: This statement is not supported by the data because both samples show that over 100 people chose 9:00.
I hope this is a good answer for you and I hope you have a nice day.
