To solve this problem yo need to have the "x", the "y", and the radius. To find the radius since it is not given we use the formula.

sq rt(-3^2+1^2)

sq rt(9+1)

sq rt(10) would be the length of the radius in this case.

Then we use the sine cosine and tangent fractions

sin:y/r

cos:x/r

tan:y/x

With the values plugged in the equations are

SIN:1/sqrt(10) Since there can´t be a sq rt in hte denominator we change it to 1(sq rt(10))/10

COS:-3/sqrt(10) Since there can´t be a sq rt in the denominator we change it to -3(sq rt(10))/10

TAN:1/-3 This one can stay the same.

This would be the measures of SIN, COS, and TAN.

What additional information is obtained by measuring two individuals on an ordinal scale compared to a nominal scale
velikii [3]

The direction of the difference between the 2 measurements.

<h3>What is nominal and ordinal scale with example?</h3>
  • Examples of data for a nominal scale include a person's gender, ethnicity, and hair color.
  • On the other hand, an ordinal scale requires putting data in a certain order, or in relation to one another and "ranking" each parameter (variable).

<h3>What is the difference nominal and ordinal?</h3>
  • Ordinal data has a preset or natural order, whereas nominal data is categorized without a natural order or rank.
  • A number that can be measured, however, will always be present in numerical or quantitative data.

<h3>What is an example of a ordinal scale?</h3>
  • First place would go to a student with a score of 99 out of 100; third place would go to a student with a score of 92 out of 100; and so on.

Evaluate the expression below if<br> a = 8 and b=-5<br> I a l - I b I
Grace [21]
The answer should be 3 since its the absolute value and thats just how far a number is from 0 so it would be 8-5=3
