please show full work for 5 stars

Assume that BMI in the US follows a normal distribution with mean 27 and standard deviation 6. The National Heart, Lung, and Blood Institute defined the following BMI categories: Underweight: BMI 18.5 Normal Weight: 18.5 BMI 25 Overweight: 25 30 What is the probability of falling into each group? Find the intervals that include 95% of the population. What is the probability of being underweight OR obese? What is probability of having a BMI over 29.2?

Explanation / Answer

since the acceleartion of the block is zero. net force on the block =0 => F = kinetic friction force +mg*sin(theta) => F = uk*mg*cos(theta) + mg*sin(theta) => F = 0.2*20*9.8*cos30 + 20*9.8*sin30 => F = 131.95 N so, power of force F = F*v = 131.95*5 = 659.75 W
