Write the System of linear equations represented by the augmented major to the right use X,Y,Z for the variablesWrite the equati
on represented by the third row
1 answer:
On the augmented matrix, each row represents an equation of the linear system. From left to right, the first three elements of the row represent the coefficients of the variables in order, the last element represent the right side of the equation.
On the third row we have the elements 3 8 0 4, which gives to us the following equation

Answer:
205 ft
Step-by-step explanation:
Let w represent the width of the rectangle. Then the length is (6w-17) and the area is ...
A = LW
7585 = (6w-17)(w)
6w² -17w -7585 = 0
Perhaps most straightforward is using the quadratic formula to solve this.
For ax² +bx +c = 0, the solution is x = (-b±√(b²-4ac))/(2a). For the above quadratic, the solution is ...
The width is 37 feet, so the length is ...
6(37) -17 = 205 . . . feet
The length of the rectangle is 205 feet.
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
