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.

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

Answer:
The inverse of a function is the reflection of a function over the line y=x. Therefore, this will reflect the function over the line of symmetry.

As the line of symmetry in this case is the x-axis, the inverse function can be found by switching the x and y values.

So we have f(x) = 1.5x + 100, and the inverse function is therefore y=1.5x+100

Answer:

Step-by-step explanation:

The equation of the line that passes through the point (6, -3) and has a slope of {m} = - k is →

y = - kx + (6k - 3).

The general equation of a straight line is -

y = mx + c

where -

{m} → slope

{c} → y - intercept

Given is the line that passes through the point (6, -3) and has a slope of {m} = - k.

We can write the general equation as -

y = mx + c

Now -

{m} = - k                     .... Eq { 1 }

We can write -

y = - kx + c

For the point (6, - 3), we can write -

- 3 = - 6k + c

{c} = 6k - 3                           .... Eq { 2 }

We can write the equation of the line as -

y = - kx + (6k - 3)

Therefore, the equation of the line that passes through the point (6, -3) and has a slope of {m} = - k is →

y = - kx + (6k - 3).

The glide reflection maps triangle ABC to triangle A'B'C' is (x, y) -> (x + 8, -y)

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The rule for the glide reflection is to first reflect the point across the y-axis and then translate the point 8 units to the right. Mathematically, this can be written as:

(x, y) -> (x + 8, -y)

So, to apply this rule to the vertices of triangle ABC, we would do the following:

A(-4, -2) -> (A(-4, -2) + 8, -(-2)) = A'(4, 2)

B(-2, 6) -> (B(-2, 6) + 8, -(6)) = B'(6, -6)

C(4, 4) -> (C(4, 4) + 8, -(4)) = C'(12, -4)

And so, the glide reflection maps triangle ABC to triangle A'B'C'.

Answer: -5

Step-by-step explanation:

To solve for x, you must use inverse operations.

We must move the 12 from the right, to the left in order to solve for x.

The inverse of addition, is subtraction.

Subtract 12 from both sides

7 - 12 = x + 12 - 12

To subtract a bigger number from a smaller number, flip it around, and make your answer negative

12 - 7 = 5

7 - 12 = -5

Something minus itself is 0

-5 = x + 12 - 12

-5 = x + 0

We like to have x on the left, and the = is symetrical.  Just flip it around

x = -5 + 0

x = -5

Verify

7 = -5 + 12

7 = 12 - 5

The mean number of absences for the sample of 50 students will fall within this range.

The 95% confidence interval for the mean number of absences for the sample of 50 students can be calculated using the formula: X ± z*(σ/√n), where X is the sample mean, z is the critical value of the normal distribution at a 95% confidence level (1.96), σ is the population standard deviation (1.4), and n is the sample size (50). The confidence interval can be calculated as follows: X ± 1.96 (1.4/√50) = X ± 0.246. Therefore, the 95% confidence interval for the mean number of absences for the sample of 50 students is 0.902 to 1.296.

The formula can be interpreted as follows: the sample mean is likely to fall within the interval of 0.902 to 1.296, plus or minus 1.96 times the standard deviation of the population divided by the square root of the sample size. Since the population standard deviation is 1.4 and the sample size is 50, the interval is 0.902 to 1.296. This interval gives us a 95% confidence that the mean number of absences for the sample of 50 students will fall within this range.

Given,

Quadrilateral ABCD

A(-3,2)

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].

Box plots are a graphical tool used in statistics to show the concentration of data. They also demonstrate how far the extreme numbers differ from the majority of the data. The smallest value, the first quartile, the median, the third quartile, and the maximum value are used to create a box plot.

Use a horizontal or vertical number line and a rectangular box to make a box plot. The axis's ends are labelled by the smallest and largest data values. One end of the box is marked by the first quartile, while the other end is marked by the third quartile. Approximately half of the data is included within the box. From the box's ends to the smallest and greatest data values, the "whiskers" extend. The median or second quartile can be in the middle of the first and third quartiles, or it can be either one or the other.

For purple and blue, the number of successful outcomes is the same (2 and 3, respectively) and the total number of outcomes is 8, so the probability of landing on either color is equal.

The third bit of output, Y[2], can be implemented using AND, OR, and NOT gates as follows:

Y[2] = A[1] * B[1] + (A[1] + B[1]) * (A[0] * B[0])

This can be simplified to Y[2] = A[1] * B[1] + A[0] * B[0]. That is, the third bit of output Y[2] is equal to the product of the first bits of both inputs, A[1] and B[1], plus the product of the second bits of both inputs, A[0] and B[0].

The third bit of output, Y[2], can be implemented using AND, OR, and NOT gates to calculate the sum of the product of the first bits of both inputs, A[1] and B[1], plus the product of the second bits of both inputs, A[0] and B[0].
