Answer:
Step-by-step explanation:
Approximately 95% of the population has IQ scores between 70 and 130. Approximately 99.7% of the population has IQ scores between 55 and 145. Only approximately 0.3% of the population has IQ scores outside of this interval (less than 55 or higher than 145).
If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line<span>. If a system has no solution, it is said to be </span>inconsistent<span> . The graphs of the </span>lines<span> do not intersect, so the graphs </span>are parallel<span> and there is no solution.
Sorry, this is a general answer. I could not view the graph below...</span>

Answer: f(x)=567(1/3)^x
Step-by-step explanation:
At x = 0 y = 567
at x = 1 y = 567 - 567(1/3)
at x = 2 y = 567 - 567(1/3)(1/3)
at x = 3 y = 567 - 567(1/3)(1/3)(1/3
Answer:
<em>y = -2x - 4</em>
Step-by-step explanation:
<em>y + 1 = -2x - 3</em>
<em>Subtract 1 from both sides to get the y by itself</em>
<em>y = -2x - 3 - 1</em>
<em>Simplify (Combine Like terms)</em>
<em>y = -2x - 4</em>
