Answer: b=-8/5

Step-by-step explanation:

Additive inverse,

Multiplicative inverse,

−

Explanation:

For a number

, it's multiplicative inverse

is such that

⋅

which is the multiplicative identity.

For a number

, it's additive inverse

would be such that

where

is additive identity.

Thus, for

−

It's additive inverse be

Then

−

Now, adding

to both sides,

Let the multiplicative inverse be

Then

⋅

⇒

−

⋅

Multiplying both sides with

−

A Pentagon is transformed according to the rule R0, 180°. Which is another way to state the transformation?

postnew [5]

The another way to state the transformation would be $(x,y)>(-x,-y)$

<u>Solution:</u>

Rotation about the origin at $180^\circ$ : $R_{180^\circ}A \rightarrow O = R_{180^\circ} (x, y) \rightarrow (-x,-y)$

The term R0 means that the rotation is about the origin point. Therefore, (R0,180) means that we are rotating the figure to $180^\circ$ about the origin.

So, the transformation of the general point (x,y) would be (-x,-y) when it is rotated about the origin by an angle of $180^\circ$ .

Hence according to the representation, the expression would be $(x, y) \rightarrow (-x, -y)$ .

You are given that claims are reported according to a homogeneous Poisson process. Starting from time zero, the expected waiting

maxonik [38]

Answer:

1.732

Step-by-step explanation:

You are given that claims are reported according to a homogeneous Poisson process

LetX be the waiting time from 0 to second claim

X is Poisson with averageof 3 hours.

We know in a Poisson distribution the mean = variance

Hence average waiting time = mean = 3

This will also be equal to var(x)

Var(x) = mean of Poisson distribution= 3

Hence standard deviation = square root of variance

= $\sqrt{3} \\=1.732$
