Answer:
m=0 and m=3
Step-by-step explanation:
there are two solutions
Answer:
Step-by-step explanation:
1. Angular speed
The angular speed ω is the angle θ swept out by the satellite in a given time t.

2. Linear speed
The formula for the linear speed v is
v = rω, where
r = the distance from the centre of the Earth = 6378 km + 1250 km = 7628 km

Natural numbers are closed under division: false.
A set is closed under a certain operation if the results of that operation are always inside that set.
So, if natural numbers were closed under division, the division of two natural numbers would always be a natural number.
You have plenty of counterexamples, to pick one you may divide any odd number by 2: 5/2 is not a natural number.
Negative numbers are closed under addition: true.
Let
be two positive numbers. So,
are two negative numbers. Their sum is

And since
is positive, we deduce that
is negative, so the sum of two negative numbers is still negative.
Prime numbers are closed under subtraction: false.
This would mean that the subtraction of two primes is also a prime. Again, there are many counterexamples: 7 is prime and so is 3, but their difference 7-3 is 4, which is not prime.
When a finite number of samples are drawn from a larger population, the sample mean of that sample, while usually close to the population mean, is not the same thing. A population mean, on the other hand, is a description of pretty much ALL of whatever is being examined.
Example of population: Everyone in the USA
Example of a sample: One person, chosen at random, from each of the 50 states
