Let Z be a standard normal variable. Find the value of z if z satisfies P(Z > z) = 0.6331.
alisha [4.7K]

Answer:

z = -0.340

Step-by-step explanation:

We are given that Z is a standard normal variable.

We have to find the value of z such that

P(Z > z) = 0.6331

P( Z > z)=0.6331  

= 1 -P( Z \leq z)=0.6331  

=P( Z \leq z)=1 - 0.6331 = 0.3669  

Calculation the value from standard normal z table, we have,

P(z \leq -0.340) = 0.3669

Thus,

z = -0.340

Which ordered pair maximizes the objective function P = 3x + 8y?
Lubov Fominskaja [6]

Correct answer is C.

Substitute each of those ordered pairs in until you get the largest number so: (0,0)=3(0)+8(0)=0 

(2,7)=3(2)+8(7)=62 

(5,6)=3(5)+8(6)=63 

(8,1)=3(8)+8(1)=42 

SO the answer would be (5,6)

Do you agree? explain why or why not
castortr0y [4]
No. when plugging 4 into the equation, 0 is not the final result. instead it is 6. 

square root of 2(4)+1 = square root of 9 = 3 

3+3 = 6
and 6 is not 0 so x cannot = 4

Hey can you please help me posted picture of question
Zinaida [17]
The inverse functions have a property that the composition of two inverse functions always results is x. 

From the given options, only the pair given in option B result in the composition equal to x.

F(x)= \frac{12}{x}-18 \\  \\ 
G(x)= \frac{12}{x+18} \\  \\ 
F(G(x))= \frac{12}{ \frac{12}{x+18} }-18 \\  \\ 
F(G(x))= \frac{12(x+18)}{12}-18 \\  \\ 
F(G(x))=x+18-18=x

This proves, F(x) and G(x) are inverse of each other.

So the answer to this question is Option B
