Answer:
0.015 is the approximate probability that the mean salary of the 100 players was less than $3.0 million
Step-by-step explanation:
We are given the following information in the question:
Mean, μ =$3.26 million
Standard Deviation, σ = $1.2 million 100
We assume that the distribution of salaries is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling =
P(mean salary of the 100 players was less than $3.0 million)
Calculating the value from the standard normal table we have,
0.015 is the approximate probability that the mean salary of the 100 players was less than $3.0 million
Answer:
The value of A is 12 and Value of B is 18
Step-by-step explanation:
A+B = 12+18 = 30
A:B = 12:18 = 2:3

Percent errors are calculated by dividing the absolute value of the errors by the exact length. What the student did wrong here is that he or she divided the given measurements by the exact lengths, which should not be the case.
Correct percent errors:
19 cm
percent error = (I19 - 20I / 20) x (100%) = 5%
21 cm
percent error = (I21 - 20I / 20) x (100%) = 5%
Answer:
If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.
hope it helps
