Answer:

  • m = j +k
  • n = 2i +k

Step-by-step explanation:

There are <em>an infinite number of possibilities</em>. Any vector whose dot-product with p is zero will be perpendicular to p.

Let m = 0i +1j +ak. Then we require ...

  m·p = 0 = 0×1 +1×2 +a(-2)   ⇒   0 = 2 -2a   ⇒   a = 1

m = 0i +1j +1k

__

Let n = 2i +0j +bk

  n·p = 0 = 2×1 +0×2 +b(-2)   ⇒   2 -2b = 0   ⇒   b = 1

n = 2i +0j +1k

Which data value is farthest from the mean? How far you is this value from the mean? Round to the nearest hundredths. 34,37,48,3
boyakko [2]

Answer:

48; 14.90 or 14.9

Step-by-step explanation:

First you have to take the mean of the data set.

In order to do this, we take the sum of all of the data points and then divide them by the number of values like so...

\frac{34+37+48+32+25+34+35+23+33+30}{10}

The answer to this is 33.1.

Now we have to find the value furthest from this value. In order to do this, we are going to take the highest (48) and the lowest value(23). Then we compare their distance from 33.1. After this, we can tell that 48 is further from 33.1 than 23 is.

Then for the second part, 48-33.1 = 14.90 and that is how far the value is from the mean.

When working with scientific data the average of a data set is called?
polet [3.4K]
<h2>Answer:</h2>

When working with scientific data the average of a data set is called:

                  Mean of the data.

<h2>Step-by-step explanation:</h2>

We know that in a given set of data the mean is calculated by finding the ratio of the sum of all the data points of the set to the total number of data points which is also known as the average of the data points.

                  Hence, the average of a data set is called :

                                  Mean of data set

0.3x ≥ 0.6
Divide both sides by 0.3,
0.3x / 0.3 ≥ 0.6/0.3
x ≥ 2

So, your final answer is x ≥ 2

Hope this helps!
