Answer:
<em>24 square yards</em>
Step-by-step explanation:
Find the diagram attached.
The area of the diagram = Area of rectangle + Area of triangle
Area of rectangle = 3 * 4
Area of rectangle = 12 square yards
Area of triangle = 1/2 * base * height
Area of triangle = 1/2 * 6 * 4
Area of triangle = 12 square yards
Area of the diagram = 12 + 12
Area of diagram = 24 square yards
<em>Hence 24 square yards of carpeting is needed</em>
Answer:
2.7 years
Step-by-step explanation:
When equal value is added or subtracted from each data item, the mean changes by such a value. However, the standard deviation does not change. The standard deviation measures how far the data items are from the mean. Because the mean has been changed by equal amount as the data items, the average "distance" of the data item from the mean does not change.
Of note is that the standard deviation would change if each item was multiplied by the same factor. In that case, the standard deviation would be multiplied by the same factor as well as the mean.
