Answer:
t = 60/n
Step-by-step explanation:
The original equation we know is y = k/n
Since 12 people can assemble the set in 5 hours, when y is 5, n will be 12.
We can now input that value into the equation.
--> 5 = k/12
--> 5(12) = k/12 (12)
--> 60 = k
--> k = 60
The equation to represent the situation can be written as:
t = 60/n
and that is our final answer!
A.) Here, w = 550kg/m^3.
Therefore, S = (0.032(550) - 2.5)/10000 = 0.00151
After drying, the beam will be (1 - 0.00151) x 12.027 = 12.009
b.) 0.0012 = (0.032w - 2.5)/10000
0.032w - 2.5 = 12
0.032w = 12 + 2.5 = 14.5
w = 14.5/0.032 = 453 kg/m^3
Therefore, the required water content is 453 kg/m^3

Answer:
r = 0.9
Step-by-step explanation:
Correlation is denoted by r. r² is usually used to measure variation along the line as a fraction of the total variation.
We are told class attendance explained 81% of the variation in grade index among the students. Thus, for this regression, the variation is;
r² = 81%
Or r² = 0.81
Thus, the numerical value of the correlation r would be;
r = √0.81
r = 0.9
