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
Answer: Down Because Say if you have a 20% grade that's considered an F and then you work up to fix that grade and get an 80 that's a b so u basically went up a grade
Step-by-step explanation:
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)
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.
