Based on the population mean, the mean of the distribution sample means would be 204.6. The standard deviation would be 0.22.
<h3>What are the mean and standard deviation of the distribution?</h3>
The mean of the distribution sample means is the same as the population means which is 204.6.
The standard deviation can be found as:
σₓ = σ / √n
= 3.1 / √197
= 0.22

Answer:
x=9
Step-by-step explanation:
Isolate the variable you are solving for.
In this case, -5x needs to be divided by -5 to isolate x. But you must do to one side of the equation what you did to the other, so -45 must also be divided by -5x.
-5x/-5=-45/-5
x=9
9000 equals to 900 tens. ( 1. 9×10=90,
2. 90×10=900,
3. 900×10=9,000. )
