let x be a normal random variable with a mean of 2.69 and a standard deviation of 4.76. a)calculate the corresponding standardized value (z) for the point x

For the function, the x-intercept of g(x) is at (5,0).

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input.

Given f(x) = ln(x)

and g(x) = -f(x - 4)

the function is

g(x) = -ln(x - 4)

when x = 5

g(x) = -ln(5 - 4)

g(x) = -ln1

g(x) = 0

the coordinates are (5, 0)

Hence the x-intercept is (5, 0).

Answer:

a + c = 1250

$7.00a + $5.50c = $7979

Step-by-step explanation:

Making the system of equations for the number of tickets involved how many attended and who attended

It's showing 1250 attended and children and adults showed up. Let's a = adults and c = children

a + c = 1250 <--- that's saying adults + children equal 1250

For $ earned, it involves how much each ticket was and the total cost

Looks like we have prices for a and c and the total cost which was 7979. Since adults were 7.00, we'll call that 7.00a. And for children it was 5.50, we'll call that 5.50c

Putting it together 7.00a + 5.50c = 7979 because all the $7.00 tickets plus all the $5.50 tickets cost $7979

The given of the system of equation is has  No solution, parallel lines.

To give a geometric description of the given system of equations.

The geometric description of a system of equations in 2 variables mean the system of equations will represent the number of lines equal to the number of equations in the system given.

A permutation, on the other hand, would require the order of the items to be specific. In this game, the order of the numbers doesn't matter, making it a combination.

The second situation is a combination. In this scenario, you are choosing 5 out of 20 different potato chips, and the order in which you choose them doesn't matter. Whether you choose chips 1, 2, 3, 4, and 5, or chips 5, 4, 3, 2, and 1, the combination is still the same.

Step-by-step explanation:

Spinner 1 is divided into 6 congruent sections.

There are 3 red sections, 2 blue sections and 1 yellow section.

Therefore, the probability of spinning each of the three colors is:

    [tex]\bullet \quad \sf P(B_1)=\dfrac{2}{6}=\dfrac{1}{3}[/tex]

    [tex]\bullet \quad \sf P(Y_1)=\dfrac{1}{6}[/tex]

Spinner 2 is divided into 3 sections of differing sizes.

The red section is half of the spinner. The blue and yellow sections are quarters of the spinner.

Therefore, the probability of spinning each of the three colors is:

    [tex]\bullet \quad \sf P(R_2)=\dfrac{1}{2}[/tex]

    [tex]\bullet \quad \sf P(B_2)=\dfrac{1}{4}[/tex]

    [tex]\bullet \quad \sf P(Y_2)=\dfrac{1}{4}[/tex]

If each spinner is spun once, then:

The probability that both spinners both show red is:

[tex]\sf P(R_1)\;and\;P(R_2)=\dfrac{1}{2} \times \dfrac{1}{2}=\dfrac{1}{4}[/tex]

The probability that both spinners both show blue is:

[tex]\sf P(B_1)\;and\;P(B_2)=\dfrac{1}{3} \times \dfrac{1}{4}=\dfrac{1}{12}[/tex]

The probability that both spinners both show yellow is:

[tex]\sf P(Y_1)\;and\;P(Y_2)=\dfrac{1}{6} \times \dfrac{1}{4}=\dfrac{1}{24}[/tex]

Therefore, the probability that both spinners show the same colour is:

[tex]\sf P(R_1\;\&\;R_2)\;or\;P(B_1\;\&\;B_2)\;or\;P(Y_1\;\&\;Y_2)=\dfrac{1}{4}+\dfrac{1}{12}+\dfrac{1}{24}=\dfrac{9}{24}=\dfrac{3}{8}[/tex]

If each spinner is spun once, the probability of getting a red from spinner 1 and a blue from spinner 2 is:

[tex]\sf P(R_1)\;and\;P(B_2)=\dfrac{1}{2} \times \dfrac{1}{4}=\dfrac{1}{8}[/tex]

The probability of getting a blue from spinner 1 and a red from spinner 2 is:

The concentration of 1 mg/mL can be described as: 103 ug/mL and [tex]10^{9}[/tex] ppm.

The concentration of a solution can be expressed as the amount of solute in a given volume of the solution. The expression for concentration can be in terms of mass per volume, such as milligrams per milliliter (mg/mL) or grams per liter (g/L), or in terms of moles per volume, such as moles per liter (mol/L).

A concentration of 1 mg/mL means that there is 1 milligram of solute in every milliliter of the solution. This can be converted to micrograms per milliliter (ug/mL) by multiplying by 1000, giving us

[tex]1mg/mL=1000ug/mL=10^{6} ug/mL[/tex].

Parts per million (ppm) is another expression of concentration. To convert mg/mL to ppm, we need to know the density of the solution, which is given as 1.00 g/mL. We can use this density to convert the mass of solute to volume and then find the ratio of solute to solution volume.

[tex]1mg/mL=1mg/1mL=1g/1000mL=1/1000 g/mL= 10^{-3}g/mL\\[/tex]

So, [tex]1mg/mL=10^{-3}g/mL=10^{-3} *10^{6} mg/mL=10^{9} ppm[/tex].

The equation that compares dollar amounts to be received or paid at different dates is the Time Value of Money (TVM) equation.

The time value of money(TVM) equation enables us to compare dollar amounts to be received or paid at various dates. This equation takes into account the concept of the opportunity cost of money and accounts for the changes in the value of money over time due to inflation and other factors. The equation calculates the present value of a future amount, or the future value of a present amount, based on an interest rate. This helps in making financial decisions by comparing the value of money at different points in time.

The equation used to compare dollar amounts received or paid at different time periods is called time value of money. This equation takes into account the effect of inflation, investment return, and the time period for which the money is being held, to calculate the present or future value of a sum of money. It helps to determine the equivalent value of money at a certain point in time, considering the opportunity cost of not having access to the money.

Plan 2- $42 per month for unlimited DVD rentals

The two plans cost the same amount

The total cost of either plan = ?

The number of DVD's rented = ?

Suppose, the number of DVD's is n

So, cost in plan 1,

=  membership fee  +  n x (charges $1 for every DVD)

=   11 + n x 1

=   11 + n

And, cost in plan 2,

=  42

According to given condition,

cost is equal in both cases,

11 + n = 42

n = 31

Hence, the total cost and number of DVD's are respectively,  45 & 31

The system of equations has its solution to be (4, 0)

From the question, we have the following parameters that can be used in our computation:

. 3x + 4y = 12

2x + y = 8

Make y the subject

y = 8 - 2x

So, the second equation becomes

3x + 4(8 - 2x) = 12

Open the brackets

This gives

3x + 32 - 8x = 12

So, we have

-5x = -20

Divide

x = 4

Recall that

y = 8 - 2x

So, we have

y = 8 - 2(4)

y = 0

Hence, the solution is (4, 0)

The value of n/p = 5n/3p.

It is a branch of mathematics that deals with the occurrence of a random event.

Let's assume that the total number of numbers in the list is T. Therefore, p + n = T.

The probability of picking a positive number is 3/5.

So p/T = 3/5.

Ratio of the number of negative numbers to the number of positive numbers is n/p.

Divide the two equations we get

n/p = (n/T) / (p/T) = (n/T) / (3/5) = (5/3) * (n/T) = 5n/3p

Hence, the value of n/p = 5n/3p.
