Answer: the man's claim is true.
Step-by-step explanation:
Given that 30% of the well find water at a depth <=100 feet
P(X<=100) = 0.30
If the man's prediction work well the probability of finding well at less than 100 or equal should be high fwhen calculated from his results. So give 27 out of 80 wells
P(X<=100) = 27/80
P(X<=100) = 0.3375
Since 0.3375 > 0.3
The man's claim is true.
If ur getting 30% off, then ur paying 70%
70% of 90...
0.7(90) = 63 <== discount price
Answer:
a) Δx = -35ft
b) Δx = -25ft
c) Kyle traveled 10ft more than John
Step-by-step explanation:
We define a coordinate reference system() in which y = 0 corresponds to the water surface.
a) The initial position of Kyle in our coordinate reference system is:

and his final position is:

Therefore, he traveled
Δx = 
b) The initial position of John in our coordinate reference system is:

and his final position is:

Therefore, he traveled
Δx = 
c) Then, Kyle traveled 10ft more than John
you can't really see the question it's too blurry
That’s right they both equal 67
