how does finding the square root of a square root of a number compare to finding the cube root of a number? use the number 64 in
professor190 [17]
Instead of finding a number multiplied by itself twice, you look for a number multiplied by itself three times. For example, 4 is the square root of 16 because 4*4=16. 4 is the cube root of 64 because 4*4*4=64

Help please!!

Answer:  (1,-1)

Step-by-step explanation:

Midpoint of BC=(6+4)/2, (3–1)/2. =(5,1)

Slope of BC is (3+1)/4–6)= 4/-2 = -2

Slope of perpendicular bisector of BC =+1/2

Eqn of perpendicular bisector is : Y-1 =1/2 (x-5)

Y=1/2 •(x-5) +1

Midpoint of AB. (6–2)/2, (3–1)/2 ={2,1)

Slope of AB is(3+1)/(-2–6) = 4/-8 =-1/2

Slope of perpendicular bisector = +2

Eqn of perpendicular bisector is Y-1. =2( X-2)

Y=2X-4+1 = 2X -3

Solving Y=(X-5)/2 +1

& Y=2X-3

2X-3 =(x-5/2)+1

2X-4 =(x-5/2)

4X-8 = x-5

3X =3

X=1

Y= 2×1–3= -1

Circumcentre is(1,-1)

An independent-measures study has one sample with n = 6 and a second sample with n = 8 to compare two experimental treatments. w
kifflom [539]

The df value for the t statistic for this study is 12.

To calculate the df value or degree of freedom we have to learn about test-statistic.

<h3>What is t statistics and how is it related to df(degree of freedom)?</h3>

In the field of statistics , T-statistic is the ratio of the estimated value of the perimeter to its standard error. Degree of freedom or df value denotes the number of data (from a sample) is used to calculate the estimate .

Importantly the degree of freedom is different from the sample space of an experiment.

The formula for calculating the df of a function is given by

df=N1+N2-2

So in the given question, N1=6 and N2=8

Substituting the values we get df=N1+N2-2=8+6-2=12 .

Therefore the value of the degree of freedom is 12.

To learn more about t-statistic and df values:
