The expression has no solution when k < - 5.

Hence, option B is correct.

The given inequality is

|2x + 7|-k ≤ 5

We know that,

A modulus function is a function that determines a number or variable's absolute value. It generates the size of the variable count.

A function with absolute values is another name for it.

No matter what input was provided to this function, the outcome is always favorable.

Now adding k both sides of inequality,

⇒ |2x + 7| ≤ 5 + k

When we take value of k less than -5

Then the expression |2x + 7| becomes negative.

Since it always gives absolute value,

We can see here that the dollar doesn't belong to the box.

We can see here that in order to known if the dollar belongs to the box or not, here is an explanation:

Let the single tickets = x

and the couples tickets = y

Note: $8 = 2 tickets (for couples),

Thus, 1 ticket = $4

5x + 4y = 200  -------(1)

x + y = 47 ----------- (2)

-4 × (2)

5x + 4y = 200  -------(1)

-4x - 4y = 188

x = 12

Substituting 12 in (2)

12 + y = 47

y = 47 - 12 = 35

y = 35

So, 5x + 4y = 200

5 (12) + 4 (35) = 200

60 + 140 = 200.

The mass of 405 cm³ of milk is 417.15 g.

To solve this problem need to use the formula:

mass = volume x density

The volume of milk given in the problem is 405 cm³ and the density of milk is 1.03 g/cm³.

Substitute these values in the formula to calculate the mass of the milk.

mass = 405 cm³ x 1.03 g/cm³

mass = 417.15 g

The mass of 405 cm³ of milk is 417.15 g.

To understand the concept behind this formula we need to understand what density is.

Density is defined as the amount of mass per unit volume of a substance.

It is expressed in units of grams per cubic centimeter (g/cm³) for solids and liquids.

The formula for calculating the mass of a substance is the product of its volume and density.

In this problem we have been given the volume and density of milk so we can easily calculate its mass using this formula.

The value of x is equal to 15.1 units.

In Mathematics and Geometry, the measure of each interior angle of a regular polygon can be calculated by using this mathematical equation:

Interior angle = [180 × (n - 2)]/n

Where:

n represents the number of sides of a regular polygon.

Since this regular polygon can be decomposed into 46 triangles, it ultimately implies that it has 46 x 3 = 138 sides.

Therefore, the value of each interior angle can be calculated as;

Interior angle = [180 × (n - 2)]/n

Interior angle = [180 × (138 - 2)]/138

Interior angle = 169.6⁰

For the value of x, we have:

9.5x + 26.2 = 169.6

9.5x = 143.4

x = 15.1 units.

Inverse variation is the relationships between variables that are represented in the form of y = k/x, where x and y are two variables and k is the constant value.

This means that has x increases y will decrease and vice versa.

If p is inversely proportional to q , then p = kq

when p = 2, q = 4

Answer:

8) b. 15 m²

9) c. 63.5 ft²

Step-by-step explanation:

Area of composite figure:

8) To find the area of the composite figure, we have to add the area of rectangle, area of the top triangle and the area of the below triangle.

Rectangle:

            length = 3m

            width = 2.5 m

          [tex]\boxed{\text{\bf Area of rectangle = length * width}}[/tex]

                                           = 3 * 2.5

                                           = 7.5 m²

Area of triangle:

              [tex]\boxed{\text{\bf Area of triangle =$ \dfrac{1}{2}*base*height$}}[/tex]

       Triangle1:

                    base = 3 m  ; height = 1.5 m

                   [tex]\sf Area \ of \ triangle1 = \dfrac{1}{2}*3*1.5[/tex]

                                             [tex]= 2.25 \ m^2[/tex]

       Triangle2:

               base = 3 m ; height = 2.5 + 1 = 3.5 m

               [tex]\sf Area \ of \ triangle2 = \dfrac{1}{2}*3*3.5[/tex]

                                          = 5.25 m²

Area of the figure = 7.5 + 2.25 + 5.25

                               = 15 m²

_______________________________________________________

9) To find area of the given area, add the area of rectangle1 and area of rectangle2.

      length = 5 ft ;  width =  5.5 ft

Rectangle1:

         Area of rectangle1 = 5 * 5.5

                                         = 27.5 ft²

Rectangle2:

           length = 8ft

           width = 10 - 5.5

                      = 4.5 ft²

           Area of rectangle2 = 8 * 4.5

                                           = 36 ft²

Area of the given figure = area of rectangle1 + area of rectangle2

                                       = 27.5 + 36

                                        = 63.5 ft²

The theoretical probability of Constance getting an orange ring from the coin-operated machine is 0.182. This means that out of all the possible outcomes, there is an 18.2% chance that Constance will get an orange ring.

To find the theoretical probability of Constance getting an orange ring from the coin-operated machine, we need to first understand what theoretical probability means. Theoretical probability is the likelihood or chance of an event happening based on the number of possible outcomes. In this case, the possible outcomes are the different colored rings that the machine contains.

We are given that the machine contains 5 white rings, 6 orange rings, 7 purple rings, and 15 pink rings.

Therefore, the total number of rings in the machine is 5 + 6 + 7 + 15 = 33.

The probability of Constance getting an orange ring can be calculated by dividing the number of orange rings by the total number of rings in the machine.

Therefore, the theoretical probability of Constance getting an orange ring is:

6 / 33 = 0.181818...

To express this as a decimal, we can round it to the nearest thousandth, which is 0.182.

The required number of parrots out of 400 birds which are more than 18 cm tall is 391 parrots.

Given that the heights of adult parrots are normally distributed with a mean height of 34 cm and standard deviation of 8 cm.

The formula used to calculate the z-score for the height of 18 cm is

z = (x - mean) / standard deviation

By substituting the value of mean and standard deviation gives,

z = (18 - 34) / 8.

On simplification of numerator gives,

z= -16 / 8 = -2.

To find the proportion of parrots more than 18 cm tall by calculating the area under the standard normal curve to the right of z = -2 by the standard normal distribution table.

That implies, proportion = area to right of z = -2 is approximately equal to 0.9772.

The formula used to calculate the number of parrots that is more than 18 cm tall is  proportion × total number of parrots.

That implies, the number of parrots out of 400 birds which are more than 18 cm tall is 0.9772 × 400 = 390.88 ≈ 391.

First = tan(θ)

Second = cos(θ)

The basis trigonometry identity is

sin²(θ) + cos²(θ) = 1

Divide through the equation by cos²(θ)

So, we have

tan²(θ) + 1 = 1/cos²(θ)

Subtract 1 from both sides

tan²(θ) = - 1 + 1/cos²(θ)

The margin of error for the two-proportion 95% confidence interval is 0.0662.

The margin of error for a two-proportion 95% confidence interval can be calculated using the following formula:

ME = z√(p₁(1-p₁)/n₁ + p₂(1-p₂)/n₂)

where ME is the margin of error, z is the z-score corresponding to the level of confidence (in this case 1.96 for a 95% confidence interval), p₁ and p₂ are the sample proportions, and n₁ and n₂ are the sample sizes.

Using the given information, we have:

Sample 1: n₁ = 250, p₁ = 0.90

Sample 2: n₂ = 275, p₂ = 0.85

Level of confidence: 95%

Substituting these values into the formula, we get:

ME = 1.96√[(0.90×0.10 / 250) + (0.85 × 0.15 / 275)]

ME = 0.0662
