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:
5%
Step-by-step explanation:
Given that:
Theoretical probability = 50%
The experimental probability = number of desired outcome / number of trials
Hence, experimental probability = 45 / 100 = 0.45
0.45 = 0.45 * 100% = 45%
Percentage difference in theoretical and experimental probability :
Theoretical - experimental
50% - 45% = 5%
Answer:x=1/24
Step-by-step explanation:
To find 9x(x+6)-(3x+1)^2=1
Open the brackets
9x^2+54x-(3x+1)(3x+1)=1
9x^2+54x-(9x^2+6x+1)=1
9x^2+54x-9x^2-6x-1=1
54x-6x-1=1
Collect like terms
48x=1+1
48x=2
Divide through by 48
x=2/48
x=1/24
