We get that the total dipers that Charlie's mom will use in the month of June and July will be 549 dipers.

Charlie's mom uses an average of 9 diapers a day.

Average = 9

Average means a number that is calculated by adding quantities together and dividing the total by the number of quantities.

Average = Sum of observations / number of observations

A = S / N

We know that:

June has = 30 days

July has = 31 days.

Total days = 30 days + 31 days = 61 days

N = 61

Let the sum = S be x.

Substituting the values in the formula, we get that:

9 = S / 61

S = 9 × 61

S = 549

Therefore, we get that the total dipers that Charlie's mom will use in the month of June and July will be 549 dipers.

The transformation to map triangle XYZ to triangle JLK is a reflection over the y axis, that is (x, y) ⇒ (-x, y)

Transformation is the change of the location of a point or figure on the coordinate plane. Types of transformations are reflection, translation, rotation and dilation.

Reflection, translation, rotation are rigid transformation since they maintain the shape and size of the figure, where as dilation is not a rigid transformation as it changes the size.

When 6 fewer than s is no less than −78, the solution in interval notation is (84,∞)

Interval notation is a way of writing subsets of the real number line

Given,

6 fewer than s is no less than -78

6-s < -78

Move 6 to right hand side

-s < -78-6

-s < -84

s > 84

Then the interval notation is (84,∞)

Hence, when 6 fewer than s is no less than −78, the solution in interval notation is (84,∞)

The mean absolute deviation of this data set is 0.2

The dataset is given as

0.7, 1.4, 3 and 2

Calculate the mean using

m(x) = Sum/Count

So, we have

m(x) = (0.7 + 1.4 + 3 + 2)/4

Evaluate

m(x) = 1.775

The mean absolute deviation is calculated as

Deviation = 1/n∑|(x - m(x))|

So, we have

Deviation = 1/4 * (|0.7 - 1.775| + |1.4 - 1.775| + |3 - 1.775| + |2 - 1.775|)

This gives

Deviation = 1/4 * (-1.075 + 0.375 + 1.225 + 0.225)

Evaluate

Deviation = 0.1875

Approximate

Deviation = 0.2

Hence, the mean absolute deviation of this data set is 0.2

Answer:

AC = 135 units

Step-by-step explanation:

since PQ bisects AB , then

BC = AC , that is

12x - 21 = 9x + 18 ( subtract 9x from both sides )

3x - 21 = 18 ( add 21 to both sides )

3x = 39 ( divide both sides by 3 )

x = 13

Then

AC = 9x + 18 = 9(13) + 18 = 117 + 18 = 135

Stephanie did Step 3 wrong as instead of adding 10, she subtracted it.

We are given that Stephanie attempted to solve the equation 5 − 3 k = 2 ( k − 5 ).

5 - 3 k = 2 ( k - 5)

5 - 3 k = 2 k - 10

5 = 2 k + 3 k - 10

5 = 5 k - 10

5 + 10 = 5 k

15 = 5 k

15 / 5 = k

Considering the definition of volume and volume of a cube, the edge length of the fish tank is 6 inches.

All matter occupies a space that can vary depending on its size. This space can be defined by volume, which is defined as the extension of an object in its three dimensions. That is, the volume corresponds to the measure of the space that a body occupies.

The cube is a polyhedron or three-dimensional geometric figure, with six equal sides, each of which is a regular polygon, that is, a square. In other words, a cube is a body made up of six faces that are square.

The volume of a cube is equal to the measure of its side to the cube:

Volume = side x side x side = side³

In this case, you know that:

Replacing in the definition of volume of a cube:

216 cubic inches = side³

Solving:

∛216 cubic inches= side

The coordinates of the vertices of the image after a reflection

in the x-axis is K(4, 2) , L(6, 1) and M(5, 5).

A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.

Given:

A KLM has coordinates K(4, -2), L(6, -1), and M(5, 5).

According to given question we have

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the x-axis is (x, -y).

So,

K(4, -2) can changed to K(4, 2) .

L(6, -1) can changed to L(6, 1).

M(5, 5) can changed to M(5, 5).

Therefore, the coordinates of the vertices of the image after a reflection

Changing [f(-1) = 1] into coordinate points, we get (x₁, y₁) = (-1, 1),

Changing [f(2) = 7] into coordinate points, we get (x₂, y₂) = (2, 7),

Also, changing [f(1) = 1] into coordinate points, we get (x₃, y₃) = (1, 1),

And finally, changing [f(3) = 0] into coordinate points,

We get (x₄, y₄) = (3, 0).

As per question statement, we are provided with Four separate functions, as follows, [f(-1) = 1], [f(2) = 7], [f(1) = 1] and [f(3) = 0].

We are required to convert the above mentioned functions into coordinate points.

To solve this question, we need to know the standard form of conversion of functions into coordinate points, which goes as [y = f(x)], i.e., the ordinate is a function of the abscissa.

Thus comparing [y = f(x)] to [1 = f(-1)], we get (x, y) = (-1, 1).

Similarly, comparing [y = f(x)] to [7 = f(2)], we get (x, y) = (2, 7),

Comparing [y = f(x)] to [1 = f(-1)], we get (x, y) = (-1, 1),

And finally, comparing [y = f(x)] to [0 = f(3)], we get (x, y) = (3, 0).

Answer:

Algebraic Expressions- An algebraic expression (or) a variable expression is a combination of terms by the operations such as addition, subtraction, multiplication, division, etc. For example, let us have a look at the expression 2x + 4. Thus, we can say that 2x + 4 is an example of an algebraic expression.

Here are more examples:

• 5x + 4y + 10

• 2x2y - 3xy2

• (-a + 4b)2 + 6ab

To simplify an algebraic expression, we just combine the like terms. Hence, the like variables will be combined together. Now, out of the like variables, the same powers will be combined together

Multiply the numbers

   x - 3 . 5x – 3x -12 - 4x + 18x - 7

= x – 15x - 3x – 12 – 4x + 18x – 7  

  Subtract the numbers

= x – 15x – 3x – 12 – 4x + 18x - 7

= x – 15x – 3x – 19 - 4x + 18x

The distance an object falls in 3 seconds is 380.16 ft.

According to the question we have been given an equation of the distance that an object falls in t seconds, which is

                       d = [tex]\frac{1}{2} g t^{2}[/tex]

where,    d = distance

               g = 84.48 ft/sec²

                t = time.

We need to find the distance an object falls in 3 seconds. That is we have to find d when t = 3 seconds

Putting the required values  in the above formula we get

      d = [tex]\frac{1}{2} (84.48) (3)^{2}[/tex]

      d = 760.32/2

Answer:

The correct answer is 64 marbles.

Step-by-step explanation:

Let's analyze the information we have:

Jill has 4 bags of marbles.

In each bag she has 16 marbles (in each one she has 3red, 5green, 2 yellow, and 6black)

If each bag has 16 marbles, and she has 4 bags, then we must multiply the contents of each bag by 4.

And we do it as follows:

16 x 4 = 64

Therefore, we can say that Jill has 64 marbles.

Answer:

There is 16 in each bag so there is 64 marbles in total.

Step-by-step explanation:

3 + 2 = 5

5 + 5 = 10

10 + 6 = 16

16 x 4 (16 + 16+ 16+ 16) = 64

The probability of a given event gives a result of 0.00037. It is generated by applying the basic concepts of probability to the assigned problem.

What is probability?

Probability depicts the number of possibilities of how many times an event can occur. The probability of happening of an event invariably lies between 0 and 1. For a sure event, it is always 1. Its formula is given as P(E) = No. of favourable outcomes / Total no. of outcomes

Calculation of finding the probability according to the conditions specified

The entire number of cards in a standard deck = 52

Total number of favourable outcomes = 1

The probability of selecting two cards is given by P(E1) which is equal to 1 / 52

P(E1) = 1 / 52

Another card is selected without replacing the first card, so the total number of cards in the deck becomes 51. The probability of selecting a card from these 51 cards is given by P(E) i.e. (1 / 52) × (1 / 51)

P(E) = 1 / 2652

P(E) = 0.00037

Hence, the required probability is given by 0.00037.
