Accuracy describes how close a measurement is to the truest value while precision shows how close the measurements are to one another when repeated analysis of the same measurements are performed. Precision most likely is free from any any variation.
Answer:
let the speed of Allegra be x mph, then speed of Elliana is x+4 mph,
time to cover distance for Eliana is 2 hours, time to cover distance for Allegrais 2.5 hours,
since they both cover the same distance you have this,
distance (of Eliana) = distance (of Allegrais ),
distance=speed x time, so we have
speed (of Eliana) x time (of Eliana) = speed (of Allegra) x time (of Allegra),
2(x+4)=2.5x,
solve for x, then substitute back for speeds for Eliana and Allegra,
Eliana's speed = 16 + 4 = 20.
Allegra's speed = 16
Answer:
The area of the rectangle plus the area of the triangle under the line
Explanation:
In this case, the object moves with constant acceleration. Initial speed of the object is 0.
Equation of kinematics :
v = u +at
v = at
v is directly proportional to time. If means that the graph is straight line passing through origin. We know that area under v-t graph gives displacement. So, the correct option is (c).
This is most definitely a physiological hazard
