Using Chebyshev's Theorem, it is found that:
At least 75% of the exam scores fall between 76 and 92.
---------------------------
- Chebyshev's Theorem states that the percentage of measures within k standard deviations of the mean is of at least
.
- With k = 2, that is, within 2 standard deviations of the mean:
- At least 75% of the measures are within 2 standard deviations of the mean.
84 - 2(4) = 76
84 + 2(4) = 92
- Thus, at least 75% of scores between 76 and 92.

Answer:
True
Step-by-step explanation:
We are given that system of equation
x<3
y>3
We have to find that there is no solution of system of equation is true or not.
First we change inequality equation into equality equation
x=3
y=3
When x=0
0<3
It is true equation therefore, the shaded region towards the origin.
When y=0
0>3
It is false equation. Therefore, the shaded region above the origin.
From the graph
There is no solution of system of equation.
Hence, option true is correct.
