Which two of the following subsets of R4are closed under the usual operation of multiplication by scalars? Give Proof as well
1- {(a, b, c, d)| ab=0}
2- {(a, b, c, d)| a=1 b=0 c+d=1}
3- {(a, b, c, d
The function f,g and h each have the set of real numbers as their domain are defined as follows:f(x)=7-2xg(x)=4x-1h(x)=3(x-1)
Find the values of x for which:f g(x)=-15g h(x)=11f f(x)=102
thank you
1.) 2x²-3x-5=0
2.) 6x²-17x+5=0
3.) 28y²-y-15=0-For factoring in algebra, you usually see if you can get some factors of the a and of the c to FOIL (first, outside, inside, last = order of multiplica

Okay I know to get V(Y) for Y = X1 + X2 you just need to do V(Y) = a^2(X1) + b^2(X2). To get the standard deviation you need to take the square root of V(Y).
The only problem is, I dont know what to

Please show me how to find the value of Z as a function of t and m. If this is not possible, please do something to the equation to make it more pretty. It l
Suppose X has a Poisson(λ) distribution. The value of λ that gives P(X=5) closest to 0.024 is..?
Please Help!!-e^-λ *λ^5/5! = 0.024
λ^5 = 2.88*e^λ
5*ln λ = λ + ln 2.88

Thanks guys hope to hear
Hi there! I have been working forever on this question! My teacher already told us the answer was 13, but WHY? Please help me choose a method! Here is the question.
