Answer:
w·v = -87
Step-by-step explanation:
The projection of a vector on another vector is given by the dot product between the vectors.
Thus, you calculate the dot product between w and v:

So, the projection of w on v is -87
Answer:
The probability is 
Step-by-step explanation:
From the question we are told that
The maximum wait is 
The minimum wait would be 
Generally the probability that you will wait more than 25 minutes for a bus is mathematically represented as

Now given that the time a person waits is uniformly distributed and that the maximum is 30 then we can evaluate the above probability as


(-2,-5) is the answer for this by doing -6-4 and -8–2
Hello.
Ken had 6.57 yards of tape, and then used 0.5 yards of the tape. Subtract 0.5 from 6.57.
6.57 - 0.5 = 6.07
He has 6.07 of the tape left.
