Answer:

The value of the RQ is 16 unit .

Option (B) is correct .

Step-by-step explanation:

Now by using the trignometric identity

cos \theta = \frac{Base}{Hypotenuse}

Base = RQ

Hypotenuse = PQ = 8 unit

\theta = 60^{\circ}

cos60^{\circ} = \frac{RQ}{PQ}

cos60^{\circ} = \frac{RQ}{8}

cos\ 60^{\circ} = \frac{1}{2}

\frac{8}{2}=RQ

RQ = 4

     = 4 unit

Therefore the value of the RQ is 4 unit .

Option (B) is correct .

There are different types of correlation one can use based on the types of variables being examined. When conducting an analysis
JulijaS [17]

The correct option is A.

When the data are nominal or ordinal.

<h3>What are the Types of  correlation?</h3>

There are three types of correlation:

1. Positive and negative correlation

2. Linear and non-linear correlation

3. Simple, multiple, and partial correlation

<h3>According to the information:</h3>

There are different types of correlation one can use based on the types of variables being examined.

Spearman’s rho is a superb choice when you have nominal or ordinal data because Pearson’s isn't appropriate. Ordinal data have a minimum of three categories and the categories have a natural order. for instance , first, second, and third during a race are ordinal data.

<h3>Briefing:</h3>

Two variables can have some quite relationship, i.e., change in one may cause a change within the other.

If a change within the value of one variable causes a simultaneous change in the other variable in the same or opposite direction, then it’s termed as correlation, or these variables are said to be correlated. Keeping these in mind the answer to this question is When the data are nominal or ordinal

When the data are nominal or ordinal.

So the option no A is correct.

I understand that the question you are looking for is:

There are different types of correlation one can use based on the types of variables being examined. When conducting an analysis, when do you need to use spearman’s rho instead of Pearson's r ?

A. When the data are nominal or ordinal.

B. When the data are ratio or interval.

C. When the data are random.

D. Spearman's rho should never be used for correlations.

Need help please asp thank you so much
Aneli [31]

Answer:

x = -1, 3

Step-by-step explanation:

so what you need to do is graph each one because that's what the questions ask. One way for you to check your answer is to set the two equations equal to each other.

-x + 5 = x^2 - 3x + 2

you want to end up with one equation and having the equation equal 0. So add x to both sides to cancel out the x on the left side and then subtract 5 from both sides to cancel out the 5 on the left side.

0 = x^2 - 2x - 3

now you factor

0 = (x - 3) (x + 1)

x = -1, 3

11/16 + 10/12 + 6/8 =
Helen [10]

Answer:

2  13/48  or  109/48

Step-by-step explanation:

Find the least common denominator

16 * 3 = 48

12 * 4 = 48

8 * 6 = 48

Convert all fractions into the common denominator of 48

33/48 + 40/48 + 36/48

Add

109/48

Simplify

2  13/48

What is 6-2p=p+9 ?Because I don't know it​
nikklg [1K]

Hey there!

  • Firstly, you have to \bold{simplify} each of the sides of your equation
  • \bold{6-2p-p+9\downarrow}
  • \bold{6+(-2p)=p+9\downarrow}
  • \rightarrow\bold{-2p+6=p+9}
  • Now that you have that  portion out of the way, we could  move on to our second step... which is to \bold{subtract} by the value of  \bold{p} on each of your sides
  • \bold{-2p+6-p-p+9-p\downarrow}
  • \rightarrow\bold{-3p+6-9} (you get this because we solve the particular equation we added above)
  • Thirdly, you have to \bold{subtract} by the number \bold{6} on each of your sides
  • \bold{-3p+6-6=9-6\downarrow}
  • \bold{Cancel:6-6} because it equals to \bold{0}
  • \bold{Keep:9-6} because it brings us closer and closer to the answer of \bold{p}
  • Fourthly, we have to \bold{divide} by  the number \bold{-3} on each of your sides
  • \bold{\frac{-3p}{-3}=\frac{3}{-3}}
  • \boxed{\boxed{\bold{Answer:p=-1}}} \checkmark

Good luck on your assignment and enjoy your day!
