Answer:
15 units
Step-by-step explanation:
Given the equation which models the path of a stone as:
![H(x)=-5x^2+10x+15](https://tex.z-dn.net/?f=H%28x%29%3D-5x%5E2%2B10x%2B15)
At the time when the stone was thrown
x=0
Therefore:
![H(0)=-5(0)^2+10(0)+15\\H(0)=15](https://tex.z-dn.net/?f=H%280%29%3D-5%280%29%5E2%2B10%280%29%2B15%5C%5CH%280%29%3D15)
The height of the stone at the time it is thrown is 15 units.
Answer:
meters per seconds squared
Step-by-step explanation:
seconds squared cancel out and you're leftvwith just meters when
meters/seconds squared is multiplied with the seconds squared in t^2
g means gravity and
gravity is 9.8 meters per second squared

Answer:
Two standard deviations
Step-by-step explanation:
The Z score is obtained using the mean and standard deviation, according to the empirical. Rule, which gives percentage of values that lie within an interval estimate in a normal distribution ;
one standard deviation lie within 68% of the mean
Two standard deviations lie within 95%
Three standard deviations lie within 99.7%
Hence, for the question given, 95% fall within 2 standard deviations of the mean
