Answer:
200
Step-by-step explanation:
122 is 61%. Of 200
3520*5=17600. You could just use a calculator if you're going to cheat, you know.
Hey there!
Let's say that x-1 is negative:
The first step is to multiply both sides by 2:
Now, move 1 to the right, using the opposite operation:
Divide both sides by -1:
- Note: Since the negative sign is already entered, all you need to enter is 13.
I hope you find my answer helpful.
Good luck!
Have a great day!
Slope is change in y over change in x, or (y2 - y1) / (x2 - x1). Pick two points, and the change in the y-coordinates over the change in x-coordinates is the slope.
Answer:
The probability that the sample mean would differ from the population mean by greater than 0.8 kg is P=0.3843.
Step-by-step explanation:
We have a population with mean 60 kg and a variance of 100 kg.
We take a sample of n=118 individuals and we want to calculate the probability that the sample mean will differ more than 0.8 from the population mean.
This can be calculated using the properties of the sampling distribution, and calculating the z-score taking into account the sample size.
The sampling distribution mean is equal to the population mean.
The standard deviation of the sampling distribution is equal to:
We have to calculate the probability P(|Xs|>0.8). The z-scores for this can be calculated as:
Then, we have:
