Answer:40
Step-by-step explanation:
Step-by-step explanation:
The given domain is wrong.The answer written in above as domain are actually a range.Domain are the pre image of range or we shall defined it by written in X component are domain and y components are range . Therefore the actual domain Rae (5,3,4) and the range are the image of domain they are (8,9,7).
3x - y - 3z
(3*-2) - 1 - (3*-2)
-6 - 1 - (-6)
-7 + 6
-1
True since the dot product is defined as a.b=abcos(x)
since they are perpendicular x=90 cos(90)=0
hence a.b=0
Finding the mean, also known as averaging numbers, is a very useful thing to know how to do, especially when you need a precise estimate or a very accurate generalization. Means and medians are not exact numbers; however, they are based on a series of exact numbers, therefore they are precise. Finding the mean (average) is used most often when figuring out students’ grades, the price of an item, and other things such as the daily temperature. Median is used to find the mid-section of a group of numbers, and mode is used to find the most popular term of the series (the number that appears the most often).
