Answer:
B.) Orthogonal
Step-by-step explanation:
Two vectors u and v whose dot product is u·v=0 are said to be orthogonal
u = <6, -2>, v = <2, 6>
u·v = u1*v1 + u2*v2
6*2 + -2 * 6
=12 -12
=0
We assume the probability on each side is equally probable with probability 1/5.
sum=4 has outcomes:{1,4; 2,3; 3,2; 4,1} 4 possible outcomes
sum=8 has outcomes:{3,5; 4,4; 5,3} 3 possible outcomes.
Total possible outcomes = 5*5=25
there probability of rolling a sum of 4 or 8, by the law of addition, equals
4/25+3/25=7/25
Note: a regular (i.e. fully symmetric) five-sided solid does not exist, so there has to be asymmetry among the probabilities of the five possible outcomes. In addition, it does not have a "top" face, so that makes rolling a five-sided solid a little more difficult to visualize.
Your answer for -16 divided by 2 will be -8, because half of 16 is 8, but you are just in the negative numbers:)! So your answer is -8
The choice isB
all the numbers in that choice decrease in numerical order
