Which of the following illustrates the truth value of the following statements?

Answer:

T F → T illustrates the truth value of the given statements.

Step-by-step explanation:

According to Point and Line contained in Plane Theorem: <em>"If a point lies outside a line, then exactly one plane contains both the line and the point".</em>

So, the statement "A line, and a point outside the line are in exactly one plane" holds true.

According to Plane Intersection Postulate: <em>"If two planes intersect, then their intersection is a line".</em>

So, according to this postulate, two planes intersect in a plane is false.

Although two Planes in three-dimensional space are able to intersect in one of three ways:

  1. Two planes would only intersect in a plane if they are coincident.
  2. Two planes would never intersect if they are parallel.
  3. If the option 1 and 2 do not hold true, then the two planes would intersect in a line.

But, as it is not specified in the question that the planes were coincident, so we assume that two planes would intersect in a line. Hence, the statement "two planes intersect in a plane" is false.

<em>Let </em><em>p </em><em>be the statement: </em>"A line, and a point outside the line are in exactly one plane". So, the statement p is true (T).

<em>Let </em><em>q</em><em> be the statement: </em>"two planes intersect in a plane". So, the statement q is false (F).

Hence, the statement p or q is written as p ∨ q.

As p is true (T) and q is false (F), hence p ∨ q will be true (T).

i.e.

<h3>      p      q      p ∨ q </h3>

       T        F           T

So, T F → T illustrates the truth value of the given statements.

The total claim amount for a health insurance policy follows a distribution with density function 1 ( /1000) ( ) 1000 x fx e− =
gizmo_the_mogwai [7]

Answer:

the approximate probability that the insurance company will have claims exceeding the premiums collected is \mathbf{P(X>1100n) = 0.158655}

Step-by-step explanation:

The probability of the density function of the total claim amount for the health insurance policy  is given as :

f_x(x)  = \dfrac{1}{1000}e^{\frac{-x}{1000}}, \ x> 0

Thus, the expected  total claim amount \mu =  1000

The variance of the total claim amount \sigma ^2  = 1000^2

However; the premium for the policy is set at the expected total claim amount plus 100. i.e (1000+100) = 1100

To determine the approximate probability that the insurance company will have claims exceeding the premiums collected if 100 policies are sold; we have :

P(X > 1100 n )

where n = numbers of premium sold

P (X> 1100n) = P (\dfrac{X - n \mu}{\sqrt{n \sigma ^2 }}> \dfrac{1100n - n \mu }{\sqrt{n \sigma^2}})

P(X>1100n) = P(Z> \dfrac{\sqrt{n}(1100-1000}{1000})

P(X>1100n) = P(Z> \dfrac{10*100}{1000})

P(X>1100n) = P(Z> 1) \\ \\ P(X>1100n) = 1-P ( Z \leq 1) \\ \\ P(X>1100n) =1- 0.841345

\mathbf{P(X>1100n) = 0.158655}

Therefore: the approximate probability that the insurance company will have claims exceeding the premiums collected is \mathbf{P(X>1100n) = 0.158655}

UREGENTTT HELPPP<br><br> Which shows this equation in standard form? 8-4(x-y)= 2x+6
jeka57 [31]

Answer:

Step-by-step explanation:

9-4(x-y)=2x+6

9 - 4x + 4y = 2x + 6

9 + 4y = 6x + 6

4y = 6x - 3

y = 3x/2 - 3/4
