Answer: 4.85%
Step-by-step explanation: productivity = parcel delivered / number of drivers.
At when parcel delivered was 103, 000 the average number of drivers was 84 thus making the productivity to be
103,000/ 84 = 1226.19
At when the parcel delivered was 112, 800 the average number of drivers was 96 thus making the productivity to be
112, 000/ 96 = 1166.67
Thus the change in productivity = 1226.19 - 1166.67 = 59.52.
Initial productivity = 1226.19
final productivity = 1166.67
% change in productivity = change in productivity / initial productivity * 100
% change in productivity = 59.52 /1226 * 100
% change in productivity = 4.85%
<h2>Answer:</h2>
→ Friction resists motion
→ Friction is a contact force.
→ Friction is caused by microscopic bumps and ridges on surfaces.
<h2>Explanation:</h2>
As the normal force, the friction is a contact force because it result when two objects interact by a direct contact, that is, touching to each other. Friction is important in everyday life and resists motion. For example, the oil in a car engine minimizes friction between moving parts, but a car can move because the friction between the tires and the road, but <em>what about the microscopic level?</em> well, as the normal forces friction forces result from the intermolecular forces between two rough surfaces at points where they come into contact and they are electrical in nature.
In order to combine the mean and standard deviations of multiple independent variables, you simply sum the means together and you sum the variances together. Since the standard deviation is the square root of the variance, what you actually do is you take the square root of the sum of the squares of the standard deviations. So:
Means:
18 + 12 + 10 = 40
Standard deviations
sqrt(2^2 + 1^2 + 5^2) = sqrt(4 + 1 + 25) = sqrt(30) = 5.477225575
So, for Jen's entire commute, the mean is 40 minutes with a standard deviation of 5.5 minutes.
Answer:
Step-by-step explanation:
Given the rectangle of 3cm by 4cm and a circle of 1 cm inside it:
The Area of the shaded portion =Area of Rectangle-Area of Circle
Area of a Rectangle=Length X Width
Area of the circle =
Area of the shaded portion=12-3.142
