Suppose the weights of 1-year-old boys are approximately normally distributed, wild a mean of 22.8 lbs and a standard deviation of about 2.15. If we randomly select o
I-vear-old boy, what is the probability that he'll weigh more than 20 pounds

never fear papaguy is here

answer

m∠a is 90°

m∠b is 40°

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
