It has been estimated that only about 30% of California residents have adequate earthquake supplies. Suppose we are interested i

lidiya [134]

Answer:

Step-by-step explanation:

We are given that 30% of California residents have adequate earthquake supplies.

a) Ramon variable X denotes the number of the california residents that have adequate earthquake insurance

B) x can take value 1 ,2 ,3 ......

C)The distribution of random variable is geometric distribution with parameter p=0.3

The pmf of geometric distribution is

$P(X=x)=0.3(1-0.3)^{x-1} , x=1,2,3...$

D)P(X=1) or P(X=2)=P(X=1)+P(X=2)

P(X=1) or P(X=2)= $0.3(1-0.3)^{1-1}+0.3(1-0.3)^{2-1}=0.51$

$P(X \geq 3)=1-P(X$

$E(X)=\frac{1}{p}$

p is the resident who does not have adequate earthquake supplies.

p = 1-0.3 = 0.7

$E(X)=\frac{1}{0.7}=1.42$

G) $E(X)=\frac{1}{q}=\frac{1}{0.3}=3.33$

What is the inverse of the function f(x) = x 3? h(x) = one-thirdx 3 h(x) = one-thirdx – 3 h(x) = x – 3 h(x) = x 3

riadik2000 [5.3K]

The inverse of the function f(x) = $x^{3}$ is : $\sqrt[3]{x}$

<h3 /><h3>What is the inverse of a function?</h3>

The inverse of a function is that function that acts to undo a given function.

Analysis:

if f(x) = x^{3}, then let y = $x^{3}$

$\sqrt[3]{y}$ = $\sqrt[3]{x^{3} }$

x = $\sqrt[3]{y}$

Replace y with x

h(x) = $\sqrt[3]{x}$

in conclusion, the inverse of h(x) = $\sqrt[3]{x}$
