The average weight of a random sample of 50 NFL players is 244.4 pounds.
<h3>What is an equation?</h3>
An equation shows the relationship between two or more numbers and variables.
For a samples size (n) in normally distributed population, the sample mean is normally distributed, with mean μX=μ and standard deviation σX=σ/√n.
Hence for a sample of 50 NFL players with an average weight of 244.4 pounds:
Mean = mean = 244.4 pounds
The average weight is 244.4 pounds.

Answer:
y=-1+squareroot 47l /6, -1- squaroot 47l/6
Step-by-step explanation:
3x^2 +2x+4−x=0
3x^2 +x+4=0
y=-1+squareroot 47l /6, -1- squaroot 47l/6
Answer:
1. x = −2/3y+10/3
2.x = 1/3y+4/3
Step-by-step explanation:
The correct answer is A.
lets discard the other options:
For B:
B is always positive, but f(x) is not, so B graph is not the answers
For C:
C is always positive too, so it cannot be the desire graph.
For D:
D is always negative, but we know that x exponent 3 is positive for all positive numbers,
3,7,11,15,19,23,27,31
32 = 8th term.
The common difference is +4
