For this case we have the following equation:
sin (40o) = b / 20
Clearing b we have:
20 * sin (40o) = b
Therefore, the length of the AC segment is given by:
b = 12.9
Answer:
the length of AC is:
b = 12.9
Using a calculator, it is found that the correlation coefficient is of 0.997.
<h3>What is a correlation coefficient?</h3>
It is an index that measures correlation between two variables, assuming values between -1 and 1.
If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.
In this problem, we have the data-set for the weight and for the height. To find the coefficient, we insert each data-set in the calculator. Doing this, we find that the coefficient is of 0.997.

Answer:
try 63
Step-by-step explanation:
14×9=126
126÷2=63
twice the number is multiplying
so it would be 2c then add 4 more
so 2c+4 is the correct equation.
Answer is B
Answer:
Step-by-step explanation:
To be perpendicular m1(m2)=-1
-1m/7=-1
m=7
So the perpendicular line will have 7 as the linear coefficient
y=7x+b
