9.20 let x be chi-squared with k = 5 degrees of freedom. (a) what is p[x > 1]? (this exact calculation requires some serious integration) (b) find p[x > 1] with the normal approximation, i. e., approximate the probability assuming x ~ n(mu, sigma squared), where mu and sigma squared are the mean and variance of a gamma(5/2, 1/2).

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
