Answer: The probability that the avg. salary of the 100 players exceeded $1 million is approximately 1.
Explanation:
Step 1: Estimate the standard error. Standard error can be calcualted by dividing the standard deviation by the square root of the sample size:

So, Standard Error is 0.08 million or $80,000.
Step 2: Next, estimate the mean is how many standard errors below the population mean $1 million.


-6.250 means that $1 million is siz standard errors away from the mean. Since, the value is too far from the bell-shaped normal distribution curve that nearly 100% of the values are greater than it.
Therefore, we can say that because 100% values are greater than it, probability that the avg. salary of the 100 players exceeded $1 million is approximately 1.
Answer:
B=9
Step-by-step explanation:
b+4=2b-5
b-2b+4=-5
b-2b=-5-4
-b=-5-4
-b=-9
b=9
You either find the gradient or distance and if there are equal, therefore the opp are equal
The width of a peak depends on A. Standard deviation
-3x + 7x = -12
You need to add like terms.
4x = -12
Then, you need to divide both side by 4.
x = -3
So the answer is:
A) x = -3
