Answer:

z = 1/2 or 0.5

Step-by-step explanation:

13 - 3z = 15z + 4

   +3z    +3z

  13 = 18z + 4

  -4            -4  

      9 = 18z

      z = 9/18

      z = 1/2 or 0.5

Answer:

b. A co-payment is a flat fee for each service, and co-insurance is based on a percentage of the costs incurred.

Step-by-step explanation:

A co-payment can be defined as a relatively small fixed amount of money that is required to be paid by a patient (insured) to a service provider such as a health insurer (health maintenance organization-HMO) as medical expenses before receiving any other service. Some examples of co-payment are the payment of $15 for a visiting gynecologist, £5 for prescribed drugs, ¥20 for x-ray etc.

On the other hand, co-insurance can be defined as the amount of money a patient (insured) is required to pay for a claim or covered charge after a deductible have been satisfied and it is typically expressed as a percentage of the costs incurred. It is usually split between the policyholder and the insurer on a 20% to 80% basis.

Hence, the difference between a co-payment and co-insurance is that, co-payment is a flat fee for each service, and co-insurance is based on a percentage of the costs incurred.

Answer:

x=2, x=1/2, x=-2/3

Step-by-step explanation:

First factor and get (x-2)(2x-1)(3x+2)=0

Then you set each of these parentheses individually equal to 0. x-2=0, 2x-1=0, 3x+2=0. Then you just simplify these to get your final answer that I showed above.

Answer:

The probability is [tex]0.0228[/tex]

Step-by-step explanation:

Let's start by defining the random variable [tex]G[/tex] as :

[tex]G:[/tex] '' The amount of gasoline sold each month to customers at Bob's Exxon station in downtown Navasota ''

Therefore, if [tex]X[/tex] is a continuous random variable that has a normal distribution, we write [tex]X[/tex] ~ [tex]N[/tex] ( μ , σ )

Where ''μ'' is the mean and ''σ'' is the standard deviation.

For the random variable [tex]G[/tex] we write :

[tex]G[/tex] ~ [tex]N(2500,250)[/tex]

We need to find [tex]P(G>3000)[/tex]

In order to calculate this, we are going to standardize the variable. This means, finding the equivalent probability in a normal random variable

[tex]Z[/tex] ~ [tex]N(0,1)[/tex]

We perform this because the random variable [tex]Z[/tex] ~ [tex]N(0,1)[/tex] is tabulated in any book or either you can find the table on Internet.

To standardize the variable we need to subtract the mean and then divide by the standard deviation ⇒

[tex]P(G>3000)[/tex] ⇒ P[ (G - μ) / σ > [tex]\frac{3000-2500}{250}[/tex] ] ⇒ [tex]P(Z>2)[/tex]

Because (G - μ) / σ  ~ [tex]Z[/tex]

Finally, [tex]P(G>3000)=P(Z>2)[/tex] ⇒ [tex]P(Z>2)=1-P(Z\leq 2)[/tex] = 1 - Φ(2)

Where '' Ф(x) = [tex]P(X\leq x)[/tex] '' represents the cumulative function of [tex]Z[/tex]

Looking for  Φ(2) in any table,

[tex]P(G>3000)=P(Z>2)=1-P(Z\leq 2)=1-0.9772=0.0228[/tex] ≅ %2.28

We found out that the probability is [tex]0.0228[/tex]

Answer:

-2

Step-by-step explanation:

Answer:

Step-by-step explanation:  Simplify both sides of the equation.

0=−16t2+24

Step 2: Add 16t^2 to both sides.

0+16t2=−16t2+24+16t2

16t2=24

Step 3: Divide both sides by 16.

16t^2/16=24/16

t^2=3/2

Step 4: Take square root.

t=± √ 3/2

t=1.224745,−1.224745

Answer:

(0, -50)

Step-by-step explanation:

pick any 2 points such as (100,0)  and (120,10)

to get from point (100.0) to point (120,10) you had to rise 10 and run 20

so the slope m =rise 10/run20= 1/2

the equation of the line is (y-y1)=m(x-x1)

(y-0)=(1/2)(x-100) for the slope m=1/2 and point on the line (100,0)

y=( x/2)-50 if you distribute

compare this with the equation

y=mx+b wher m=slope and bb is y-intercept

so the y-intercept is -50

Hi there!

[tex]\large\boxed{182}[/tex]

Equation:

5a² - 2a - 10 for a = -6.

Evaluate by plugging in -6 for a:

5(-6)² - 2(-6) - 10 =

5(36) - (-12) - 10 =

180 + 12 - 10 = 182.

Answer:

These two lines are graphs of non-proportional relationships because

" They do not go through the origin " ⇒ B

Step-by-step explanation:

If two quantities x and y are proportional, then

From the given graph

∵ The first line intersects the y-axis at point (0, 3)

∴ The line does not pass through the origin

∴ The line is a graph of the non-proportional relationship

∵ The second line intersects the y-axis at point (0, -2)

∴ The line does not pass through the origin

∴ The line is a graph of the non-proportional relationship

These two lines are graphs of non-proportional relationships because

" They do not go through the origin "

Step-by-step explanation:

These Two Graphs Are non proportional because C)They do no go through the graphs

Answer:

34% of scores should fall between your score and the mean.

Step-by-step explanation:

Let X denote the score.

It is provided that X follows a normal distribution with mean 110 and standard deviation 15.

A students score, x = 95.

Compute the probability of scores that should fall between the student's score and the mean as follows:

[tex]P(95<X<110)=P(\frac{95-110}{15}<\frac{X-\mu}{\sigma}<\frac{110-110}{15})[/tex]

                            [tex]=P(-1<Z<0)\\\\=P(Z<0)-P(Z<-1)\\\\=0.50-0.15866\\\\=0.34134\\\\\approx 0.34[/tex]

Thus, 34% of scores should fall between your score and the mean.

Answer: C

x= 2pi/3

Step-by-step explanation:

The value of x will be x < π / 2. Then the correct option is B.

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The trigonometric inequality is given below.

sec(2x) < –1

We know that 1/cos 2x = sec 2x

1/cos 2x < –1

           1 < –cos 2x

 cos 2x < –1

 cos 2x < cos π

        2x < π

          x < π / 2

Then the correct option is B.
