Answer:
$110
Step-by-step explanation:
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%
Answer:
angle M = 98
Step-by-step explanation:
since they all equal 180
do 3x-16+x+6+x = 180 now add 10 two both sides and get
3x+x+x = 190
5x = 190
x = 38
now plug that in to 3x-16 to get 98
