Answer:
The distance between the astronomers and the moon was ![7.56*10^{8]](https://tex.z-dn.net/?f=7.56%2A10%5E%7B8%5D)
meters.
Step-by-step explanation:
We have that the speed is the distance divided by the time, so:
In this problem, we have that:
The reflected laser beam was observed by the astronomers 2.52 s after the laser pulse was sent. This means that 
.
If the speed of light is 3.00 times 10^8 m/s, what was the distance between the astronomers and the moon?
We have that 
m/s.
We have to find d. So:
The distance between the astronomers and the moon was meters.
D the sample mean would less closely model the population mean
Answer:
C
Step-by-step explanation:
Proof by some contradictions:
D is not a good example because she does not pay anything upfront
B is not a good example because he pays <u>everything </u>upfront with some of the money from a third party
A is not right because the 500 is a security deposit, which is a different concept from a down payment
Therefore the answer should be C, where money is payed upfront and payed after he receives the product.
