Answer:
E is not a subspace of
Step-by-step explanation:
E is not a subspace of
In order to see this, we must find two points (a,b), (c,d) in E such that (a,b) + (c,d) is not in E.
Consider
(a,b) = (1,1)
(c,d) = (-1,-1)
It is easy to see that both (a,b) and (c,d) are in E since 1*1>0 and (1-)*(-1)>0.
But (a,b) + (c,d) = (1-1, 1-1) = (0,0)
and (0,0) is not in E.
By the way, it can be proved that in any vector space all sub spaces must have the vector zero.
Here is the completed table:
Has pet Has no pet Total
7th grade 102 48 150
8th grade 107 68 175
Total 209 116 325
<h3>What is a two-way table?</h3>
A two way table is used to show the frequency of two categorical variables. Information are usually presented in rows and columns.
- The 7th grade students that have no pets = 150 - 102 = 48
- The 8th grade students that have pets = 175 - 68 = 107
- Total students that have pets = 102 + 107 = 209
- Total students that have no pets = 48 + 68 = 116
- Total = 209 + 116 = 325
