Three linear equations in three unknowns. Solve.
Answer:
1500
Step-by-step explanation:
1200/4=300
1200+300=1500
The negative sign in front of the x reflects it over the y-axis.
The -5 shifts the graph 5 units to the right.
The +7 shifts it up 7 units.
The answers are A, D and E
Let x represent the scores. With mean and standard deviation given,
The Empirical rule states that
1) About 68% of the x values lie between 1 standard deviation below and above the mean
2) About 95% of the x values lie between 2 standard deviation below and above the mean
3) About 99.7% of the x values lie between 3 standard deviation below and above the mean
If we consider this rule, then the percentage of scores that fall within 3 standard deviation (-3 to +3) is 99% because this is closer to 99.7%
