The IQR is the best measure of variability, and it equals 4.

Answer:

Equations:

A: y = 2x + 30

B: y = 3x + 6

Time to fill to 71 inches:

A: 20.5 minutes

B: 25.5 minutes

Step-by-step explanation:

Pool A: starts at 30 inches, fills at 2 inches/minute

Equation: y = 2x + 30

Pool B: starts at 20 inches, fills at 3 inches/minute

Pool B slope = filling rate = (26 - 20)/(2 - 0) = 6/2 = 3

Equation: y = 3x + 20

Pool A: y = 71

71 = 2x + 30

2x = 41

x = 20.5

Pool B: y = 71

71 = 3x + 20

3x = 51

x = 25.5

AS a fraction: 1[tex]\frac{11}{20}[/tex]

AS a decimal: 1.55

Step-by-step explanation:

4/5 + 3/4

least common multiple of 5 and 4 is 20. Conver [tex]\frac{4}{5}[/tex] and [tex]\frac{3}{4}[/tex] to fractions with denominator 20.

16/20 + 15/20

since [tex]\frac{16}{20} and \frac{15}{20}[/tex]  have the same denominator, add them by adding their numerators.

The ratio of the number of unshaded to shaded squares is 7 : 3.

Ratio is defined as the relationship between two quantities where it tells how much one quantity is contained in the other.

It is also defined as the fraction of one quantity with respect to other.

The ratio of a and b is denoted as a : b.

Given is a grid of squares which is given below.

Total number of squares = 10

Of that,

Number of shaded squares = 3

Number of unshaded squares = 7

We have to find the ratio of unshaded to shaded squares in the grid which is 7 / 3 or 7 : 3.

Ratio of unshaded squares to shaded squares = 7 : 3

Hence 7 : 3 is the ratio of unshaded to shaded.

Answer:

Answer:

2

Step-by-step explanation:

20% = 0.2

What is 20% of 10?

We take

10 times 0.2 = 2

So, 20% of 10 is 2.

Answer: C

Step-by-step explanation:

The two variables need to be eliminated. You can do this by multiplication or subtraction.

Multiply by -3 to the top equation will eliminate the x variable in the system

-3(2x - 4y = 5)

   6x - 3y = 10

==> -6x + 12y = -15

       6x - 3y = 10

adding a top with a bottom will eliminate the x

==> -6x + 6x = 0, 12y + (-3y) = 9y, -15 + 10 = -5

The sample size for the given data is 17

The sample size is a term used in market research for defining the number of subjects included in a sample size.

Given that, a sample size has an 80% confidence interval, the population standard deviation is s = 120, the margin of error to be approximately 10, We need to find the sample size,

Sample size = (z-score)²×SD×(1-SD) / (confidence interval)²

z-score of 80% confidence interval = 1.28

Sample size = (1.28)²×0.12(1-0.12)/0.10²

= 1.6384×0.12×0.88/0.01

Option (4):  The inverse of the function tells us the number of visits m that can be made for a cost of c.

What is meant by the inverse of a function?

A function takes in values, applies specific operations to them, and produces an output. The inverse function acts, agrees with the outcome, and returns to the initial function.

A function that can reverse into another function is known as an inverse function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. When a function is written as "f" or "F," its inverse is written as " f ⁻¹ " or " F ⁻¹."

Given a function,

  c(m) = 60 + 10m

where c = cost of visiting the gym

            m = number of visits

Then the Inverse function is:

   c(m) - 60 = 10m

m = (c(m) - 60) / 10

Therefore the inverse of the function tells us the number of visits m that can be made for a cost of c.

Obtuse triangle

Step-by-step explanation:

Obtuse triangle has an interior angle measuring more than 90 degrees.

the size of the stiffness matrix depends on the number of degrees of freedom and the type of elements used in the analysis. It is an important tool in structural mechanics and engineering for analyzing the behavior and performance of structures under different loading conditions.

In structural mechanics and engineering, the stiffness matrix is a mathematical representation of the stiffness of a structure, which relates the forces and displacements of the structure. The size of the stiffness matrix depends on several factors, including the number of degrees of freedom and the type of elements used in the analysis. The number of degrees of freedom (DOF) in the system determines the size of the stiffness matrix. DOF refers to the number of independent displacements or rotations that a structure can undergo in response to external forces. For example, a simple beam structure might have two DOF (vertical displacement and rotation), while a more complex structure such as a truss or frame might have many more DOF. The size of the stiffness matrix also depends on the type of elements used in the analysis. Different types of elements have different degrees of freedom and stiffness properties, which affect the size and shape of the stiffness matrix. For example, a truss element has two DOF and a constant axial stiffness, while a beam element has four or six DOF and variable stiffness properties that depend on its geometry and material properties.

In summary, the size of the stiffness matrix depends on the number of degrees of freedom and the type of elements used in the analysis. It is an important tool in structural mechanics and engineering for analyzing the behavior and performance of structures under different loading conditions.

None of the given polygons appears to be regular.

A regular polygon is a polygon with all sides and angles of equal measure. In other words, a regular polygon is a shape with straight sides that has all angles and sides of equal length.

The simplest example of a regular polygon is a equilateral triangle, which has three sides of equal length and three angles of equal measure. Another example is a square, which has four sides of equal length and four right angles of equal measure.

Figure A is a rhombus, which has opposite sides parallel and all sides equal, but it has two acute angles and two obtuse angles, so it is not regular.

Figure B is a parallelogram, which has opposite sides parallel, but not all sides and angles equal, so it is not regular.

Figure C is a right-angled triangle, which has one right angle, but not all sides and angles equal, so it is not regular.

Take A, B, C, and D as the quadrilateral's vertices, and BA is created to E. The value of x = 40.

Draw the above diagram and add the angles that are missing.

To determine the value of x, use the information provided in the accompanying diagram.

Take A, B, C, and D as the quadrilateral's vertices, and BA is created to E. (say).

Observe the illustration.

[tex]$& \Rightarrow \angle \mathrm{EAD}=70 \\[/tex]

[tex]$& \Rightarrow \angle \mathrm{EAD}+\angle \mathrm{DAB}=180 \\[/tex]

[tex]$& \Rightarrow \angle \mathrm{DAB}=180-70=110[\because E A B \text { is a straight line and } \mathrm{AD} \text { stands on it. }] \\[/tex]

Apply the total of internal angles in step two.

We are aware that a quadrilateral's inner angle total is 360.

[tex]& \Rightarrow \angle \mathrm{DAB}+\angle \mathrm{ADC}+\angle \mathrm{DCB}+\angle \mathrm{CBA}=360 \\[/tex]

To find an exponential regression equation for this set of data, we can use a calculator or spreadsheet software with built-in regression functions. Using a calculator, we can input the data points into lists and use the exponential regression function to find the equation:

x y

0 1353

1 1584

2 2037

3 2248

4 2630

5 3146

Using exponential regression, we get the equation y = 1323.119e^(0.216x).

To determine the number of bacteria present after 14 hours, we can plug in x = 14 into the equation:

y = 1323.119e^(0.216 * 14) ≈ 35433

Therefore, the number of bacteria present after 14 hours is approximately 35,433 (rounded to the nearest whole number).

The inverse function of f (x) = 1/3x - 2 is f⁻¹(x) = 3(x + 2), the value of a is 3, and the value of x-intercept is x = -2.

The sets X and Y are collectively referred to as the function's domain and co-domain, respectively.

Each element of X receives exactly one element of Y when a function from one set to the other is used.

According to the question,

f (x) = 1/3x - 2

now to find inverse ,

Add 2 to x term  and then divide by 1/3 so, we get,

f⁻¹(x) = (x + 2) / 1/3

f⁻¹(x) = 3(x + 2)

now, compare with f⁻¹(x) = a (x + 2)

a = 3
