Assume that λ=3 and μ=4 . find the lms estimate of t2 , the lifetime of another lightbulb from the same box, based on observing t1=2 . assume that conditioned on the bulb type, bulb lifetimes are independent. (for this part, you will need a calculator. provide an answer with an accuracy of three decimal places.) lms estimate of t2 :

tip $2.90

total $17.40

elli's hot cocao is more chocolaty

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
