Answer:
that is the solution to the question
This problem can solve by the rule of three.
42 installations-----------------------6 hours
147 installations---------------------- x
x=(147 installations * 6 hour) / 42 installations=21 hours.
Answer: 21 hours.
To determine the radius of the cone, we make use of the lateral surface area of the cone. The lateral surface of an object is the area of all the sides of a certain object. For a cone, it is the product of pi, the radius and the slant height (lateral height). We calculate as follows:
Lateral Surface Area = πrh
47.1 = πr(6)
r = 2.5 cm
The equation for the line of best fit can be obtained as follows, using the least square method (for more info visit http://hotmath.com/hotmath_help/topics/line-of-best-fit.html ):
mean of X = 1/6
mean of Y = 2/3
slope, m = 704/1121 = 0.6
Computing the y-intercept using the formula:
b = mean of Y - m (mean of X) = 2/3 - (704/1121)(1/6)
b = 0.562 = 0.6
Therefore, the equation of the line of best fit, given the standard relation:
y = mx + b
y = 0.6x + 0.6
