Information given:
- <u>100 passengers in each train car</u>
- <u>10 train cars total</u>
- <u>30 trains total</u>
<em>So we are trying to find the total number of passengers on all 30 trains?</em>
<u />
Step-by-step:
100 x 10 = <u>1,000 passengers per train</u>
1,000 x 30 = <u>30,000 passengers total within the 30 trains</u>
Answer: <u>30,000 passengers</u>
<em>Hopefully this answered your question :)</em>
Answer:
Perpendicular bisector theorem
Step-by-step explanation:
The illustration of the theorem is:
If point B is a perpendicular bisector of Line AC and the length of AC is 10cm
Then
Where
--- Perpendicular bisector
So, the equation becomes
Recall:
Answer:
Use the normal distribution if the population standard deviation is known.
Use the student's t distribution when the population standard deviation is unknown.
Explanation:
A mound-shaped distribution refers to the normal distribution.
A good sample size for testing against the normal distribution should be
n >= 30.
The condition for the sample size is satisfied.
However, we are not given the population standard deviation, therefore it is assumed to be unknown.
Therefore the student's t distribution should be used.
volume = 4/3 x PI x r^3
r = 10/2 =5
V = 4/3 x 3.14 x 5^3 = 523.333
523.3 cubic inches
Answer:
y=1
Step-by-step explanation:
6=2(y+2)
Divide each side by 2
6/2=2/2(y+2)
3 = y+2
Subtract 2 from each side
3-2 = y+2-2
1 = y
