Answer: approximately normal
Step-by-step explanation:
1/2 Thinking about population shape and sample size
When a population is normally distributed, the sampling distribution of the sample mean x will also be normal regardless of sample size.
Since the distribution of distances is normal, the sampling distribution of the sample mean distance will also be normal.
2/2 Answer
The sampling distribution of the sample mean distance will be approximately normal.

Answer:
C
Step-by-step explanation:
M is t so 15x400 will b C
Let x be the width
Lenght = 10x + 8.1
(10x + 8.1)2 + 2x = 515.6
22x = 499.4
x = 22.7
Area = l*w
= 22.7*235.1
= 5336.77
= 5340( nearest tens)
Answer : The value of x and y is 8 and 10 respectively.
Step-by-step explanation :
As we known that if two parallel lines are cut by a transversal line then consecutive interior angles are supplementary.
From the given figure we conclude that:
...........(1)

............(2)
...........(3)

...........(4)
Now we adding equation 2 and 4, we get the value of x.



Now we are putting the value of x in 4, we get the value of y.




Therefore, the value of x and y is 8 and 10 respectively.
