9514 1404 393

Answer:

  • 1/2V = <-9/2, 3/2>
  • -V = <9, -3>
  • 4V = <-36, 12>

Step-by-step explanation:

The scalar multiplier multiplies each of the components.

  1/2V = <-9×1/2, 3×1/2> = <-9/2, 3/2>

  -V = <(-9)(-1), (3)(-1)> = <9, -3>

  4V = <-9×4, 3×4> = <-36, 12>

Ok so for the first one it’s super simple I’m gonna do it as less complicated so it can help you :)


So first we need to convert the mixed number to an improper fraction


1 4/5 = 9/5


Now we need to reduce the numbers greatest common divisor which is 3

3/5 x 6

Now multiply the numbers


Your answer is 18/5 I hoped this help



Now for the second one

this one is a little more complicated and I don’t know how to make it sound easier so I’m gonna tell you the answer which is 580/21


The last one is the same steps we did for the first one which is 27/20



I hoped this helped you it is a little difficult but you’ll get the hang of it :)

Thomas and Pablo began arguing about who did better on their tests, but they couldn't decide who did better given that they took
Shkiper50 [21]

It should be noted that the z score for Thomas test grade is 0.237.

<h3>How to illustrate the information?</h3>

From the information, Thomas took a test in Social Studies and earned a 74.8 and there is the fact that all the students' test grades in the Social Studies class had a mean of 72.6 and a standard deviation of 9.3,

Therefore, the z score for Thomas test grade will be:

= Test score - Mean / Standard deviation

= 74.8 - 72.6 / 9.3

= 0.237.

Therefore, it should be noted that the z score for Thomas test grade is 0.237.
