For what values of a are v = a i − j + k and w = a i + a j − 3 k perpendicular? give exact values.

1 answer:

3 0

The vectors are perpendicular when their dot product is zero. That is
.. a^2 -a -3 = 0
.. (a -1/2)^2 -13/4 = 0
.. a = (1 ±√13)/2

X+(x+2)+(x+4)=3639
3x+6=3639
3x=3633
X=1211
Numbers are: 1211, 1213, 1215

X+(x+2)+(x+4)=672
3x+6=672
3x=666
X=222
Numbers are: 222,224,226

Answer:

$0.67(4)+ 36$

Option D

Step-by-step explanation:

Given that a producer ships boxes of produce to individual customers.(say x)

X is a normal random variable with mean = 36 and std dev =4 lbs

By definition of std normal variate we know that

$\frac{x-36}{4}$ is N(0,1)

75th percentile of std normal distribution is

0.675

Hence corresponding x would be

$36+0.675(4)$

Option D matches with this value

Hence answer is option D

$0.67(4)+ 36$
