I'm pretty sure its c
You just multiply 13 and 52
Answer:
y=4
y=−3
Step-by-step explanation:
(a) someone over 55
mean, mu = 22
standard deviation, sigma = 2
X=19
Z(X)=(X-mu)/sigma=(19-22)/2=-1.5
P(x>X)=1-P(x<X)=1-0.0668072=0.9331928
Therefore probability for a 55-year old to find a job in over 19 weeks is 0.9332
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, 
A Exponential growth is the answer
