Answer: C. ±0.632.
Step-by-step explanation:
We have given,
Sample size : n= 10
Significance level :
Test to check determine whether there is sufficient evidence to support a
claim of a linear correlation between two variables is a two tailed test.
Degree of freedom(df) = n- 2=8
Now , by the correlation coefficient(r) table ,
The critical r value corresponding to df = 8 and Significance level = 0.025 (0.05/2) is ±0.632.
Hence, the correct option is C. ±0.632.
Answer:
Step-by-step explanation:
4x+5y = 15
slope of line is -⅘
perpendicular to the line is 5/4
point-slope equation for line of slope 5/4 through (-4,-1):
y+1 = (5/4)(x+4)
Answer. I hope it helps you.
Answer: in this question the easiest way to find an answer is by cross multiplying ....i hope i am right
Step-by-step explanation:
1 hour=25miles
9hours=x
cross multiply which will give u
1x=25x9
1x=225
x=
x=225miles
hope this helps
OR
1hour= 25miles
9hours=x
so u know in 9hours the miles swam will obviously will be more so if it is more less will divide
which will be=×21 =225 miles
HOPE THIS HELPSSSSSSSSSS!!!!!!!!!!!!!
