Let X be a Gaussian random variable with mean µ and standard deviation σ. (a) Find the pdf of Y = (2X + 5) in terms of µ and σ. (b) Evaluate E[(2X + 5) 2 ] in terms of µ and σ. (c) If µ = 5, find σ so that P(X > 9) = 0.2. (d) If µ = 12 and σ 2 = 4, find the value of λ so that P(X > λ) = 0.10.

here, if you ever need with rounding (or other forms of arithmetic/math) again, use this:

thats the rounding one, but if you just click the top left, it shows you all the calculators you may need!

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
