Answer:
heyyyyyyyyyyyyyyyyyyyyyyyyy
Given:
Two vectors are:
To find:
The projection of u onto v.
Solution:
Magnitude of a vector 
is:
Dot product of two vector 
and 
is:
Formula for projection of u onto v is:
On further simplification, we get
Therefore, the projection of u onto v is .
Answer:
5/8
Step-by-step explanation:
Find P(x = 3 blues for the 2 draws)
two draws
Binomial probability.
we know p = 3/8 for blue, else q = 1 - q = 1 - (3/8)
X = # of blue marbles left in the bag.
apparently it looks like there are 8 marbles in the bag, 3 are blue, 5 are red
X = 3 , means the draw was a red 5/8 for the first draw
the 2nd draw can be a blue or a red so, probability is 1
P(X = 3) = (5/8) * 1 = 5/8
First, we're going to convert the mixed number into a/n improper fraction.
(4 × 8 ) + 4 = 36/8
Now we're going to divide 36/8 by 4/8 since 4/8 = 1 lap.
36 / 4 = 9.
That is how we get our answer, 9 laps.
Our final answer is 9 laps.
Hope this helps!~
