A parrellagram has two parallel pairs, while a trapezoid only has 1 pair.
Answer:
0.0012
Step-by-step explanation:
Just move the decimal places.
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
-2x-2y=-12
4x-7y=-15
Solve for x in the first equation
-2x=-12+2y
2x=12-2y
x=6-y
Plug x into the second equation
4(6-y)-7y=-15
24-4y-7y=-15
24-11y=-15
11y=39
y=3.54
Plug that into the eqaution for x
x=6-3.54
x=2.46
I can't really answer that. Sorry. But I know a YouTube account that can help you. Search up L. Moon and it will show you a list of videos.
