Answer: d. Date
Step-by-step explanation:
Some of the information printed on the bottom of a check include the check number which is typically a security measure that is used in the identification of payment so as to prevent fraud.
The routing number also informs the bank where the funds for the check can be found.
The account number informs the person that collects the check about the account that the money is coming from.
We should note that the date is at the top of the check and one has to fill it himself or herself before giving the check to the recipient.
Answer:
Below in bold.
Step-by-step explanation:
Arrange the data in ascending order:
1. 1 1 2 3 4 7 9
Median = middle number = 3.
Q1 = 1
Q3 = 7.
2. 26 31 34 38 42 66 74 78
Median = mean of 2 middle numbers = 40.
Q1 = 31.
Q3 = 74.
3. 36 45 49 52 53 64 81 87 93
Median = middle number = 53.
Q1 = 47.
Q3 = 84.
Answer:
See proof below
Step-by-step explanation:
We will use the hint. The statement of the hint holds true, as the linear span of a set of vectors T is equal to the set of linear combinations of vectors in T.
Denote the linear span of vectors with the curly brackets < >, that is, 
Let 
, then u is a linear combination of v1,v2,v3, that is, there exist scalars 
such that 
. Multiply by 3 in both sides to get 
, with 
Since , 
as real numbers are closed under multiplication. Therefore 3u is a linear combination of the vectors 
, that is,
