Answer:
The data is skewed left
Less than
Median is 22
mean is 20.2
Step-by-step explanation:
<u>median: 15,16,18,19</u>,22,22,<u>22,22,23,23</u>
mean: 15+16+18+19+(22x4)+(23x2)=
31+37+88+46=
68+134=202÷10=20.2
A vector w orthogonal to u and v can be obtained by the cross product of u and v, namely u x v. Subsequently, u x v may be reduced to a unit vector.
u<-8,-6,4>
v<10,-18,-2>
w=u x v
=
i j k
-8 -6 4
10 -18 -2
=<12+72, 40-16, 144+60>
=<84, 24, 204>
=12 < 7,2,17>
Check that w is orthogonal to u and v
w.u = 12<7,2,17><-8,-6,4> = 12(-56-12,68)=0
w.v = 12<7,2,17><10,-18,-2> = 12(70-36-34)=0
Therefore w is orthogonal to both u and v.
Unit vector of w
Answer:
5h + 3p
Step-by-step explanation:
1 hardback weighs 5 pounds, then
h hardbacks weigh 5 × h = 5h
1 paperback weighs 3 pounds, then
p paperbacks weigh 3 × p = 3p
total weight = 5h + 3p
