Answer:
2^-4, 1/16, (1/2)^4
There is a rule with exponents, if you are dividing two exponents you subtract the first exponent from the other to simplify it, also meaning it's equivalent.
So in this case 5-9 = 2^-4
The others were found by evaluation.
The first quadrant ..........
In the first quadrant, 0-90 degrees, the angle whose cotangent is is 45 degrees. The only other quadrant where cot theta is 1 is 3rd quadrant.
The 2 angles are 45 and 180+45 = 225 degrees
Answer 45 , 225 degrees.
Answer:
-8
4
-15
-8
7
42
-60
15
-9
-12
Step-by-step explanation:
-2 - 6 = -8
8 + (-4) = 4
10 + (-25) = -15
-15 - (-7) = -8
-6 - (-13) = 7
-7 x -6 = 42
-12 x 5 = -60
60/4 = 15
72/-8 = -9
48/-4 = -12
Answer:
C:It is a strong positive correlation,and it is not likely causal.
Step-by-step explanation:
Correlation refers to the relationship between the two variables i.e x and y. It has mainly two types of correlation. The first one is positive and the other one is negative. It lied between -1 to 1. The 1 represents the strong positive correlation while the -1 represents the strong negative correlation
Since the correlation coefficient is 0.74 which is nearest to 1 so it denotes the strong positive correlation and thus is not causal
Hence, the correct option is c.
