To find whether there is an association between these two let us find the correlation coefficient between these two variables.
r=-0.1975
Since |r|<0.5, correlation is weak.
Let us test the hypothesis r =0
H0:r=0
Ha:r not equals 0
Test statistic =
p =0.298
Since p value >0.10, at 90% significance level we accept that there is no association.
Answer:
130 degrees
Step-by-step explanation:
arc CA is 50 since the angle is 50 and then you would subtract from 180 since it is half the circle which leaves you with C, or 130 degrees.
Answer:
Density = Mass / volume
Problem B mass = 87.5 g and volume = 5 cm^3
Density = 87.5 / 5 = 17.5
This value is too low to be platinum

Answer:
X=½ or 3
Step-by-step explanation:
0=2x²-7x+3
0=(2x-1)(x-3)
0=2x-1 or 0=x-3
1=2x or 3=x
½=x
