Answer:
not 35
Step-by-step explanation:
it 18
Its also 40°30' because the median is also a bisector in isosceles triangle
Answer:
True
Step-by-step explanation:
since, S= D/T the distance traveled would only be 100m, it is a consatnt variable dividing it with the time it takes to reach that distance would be its speed. Unless there is an acceleration happening in that process the speed would change depending on the situation.
Answer:
By the Empricial Rule, approximately 68% of the 500 scores fell between 80 and 90
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviation of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 85
Standard deviation = 5
Approximately what percentage of the 500 scores fell between 80 and 90?
80 = 85 - 5
So 80 is one standard deviation below the mean
90 = 85 + 5
So 90 is one standard deviation above the mean
By the Empricial Rule, approximately 68% of the 500 scores fell between 80 and 90
Answer:
30in²
Step-by-step explanation:
A=1/2(4)(5+10)
A=2x15
A=30in²
