Step-by-step explanation:

The minimum of a box-and-whisker plot is the leftmost endpoint, called the "whisker". This minimum is the smallest value collected in the data.

Ans: 2/3

Step-by-step explanation:

Formula : [tex]m = \frac{y2 - y1}{x2- x1}[/tex]  (Then replace the number in )

= 3- (-1) / 4 - (-2) = 4 / 6 = 2 / 3

Step-by-step explanation:

the slope is always the ratio "y coordinate change / x coordinate change" when going from one point on the line to another.

so, when going from (-2, -1) to (4, 3)

x changes by +6 (from -2 to 4).

y changes by +4 (from -1 to 3).

therefore, the slope is

+4/+6 = 4/6 = 2/3

The volume of the given shape will be equal to V=2827.42 cubic inches.

The volume is defined as the space occupied by the object in the three-dimensional plane. It requires three coordinates to find the volume of any object.

Here it is given in the question that:-

Radius of the semicircle=12 inches

Height of the cylinder =13 inches.

Now the volume will be calculated as:-

Total volume of the figure will be the sum of the Volume of the semicircle and the Volume of the cylinder.

= 2πr³+πr²l

= 2xπx(6)³+πx(6)²x13

=1357.16+1470.26

=2827.42  Cubic inches                      

Hence the volume of the given shape will be equal to V=2827.42 cubic inches.

The statement that proves that parallelogram KLMN is a rhombus is. The slope of KM is 1 and the slope of NL is –1.

This is a type of quadrilateral that has four sides of which they are all equal.

Hence, given that KLMN is a parallelogram, K(7,7), L(5,3), M(1,1) and N(3,5).

We know that they bisect each other and if the diagonals of a parallelogram are perpendicular to each other then the parallelogram is a rhombus.

Therefore, The slope of KM is 1 and the slope of NL is –1.

Minimum number of hours which a person need to rent a tube in order for the second company to be a better deal is more than 2.5 hours.

A mathematical model is the model which is used to explain any system, the effect of the components by study and estimate the functions of systems.

Two companies (first and second) offers river tubing trips and the rates of them are as follows: The first company charges $7.50 rental fee for one tube, with a charge of $3.00 an hour.

For the x hours, the charge of the company is,

7.50+3.00x

The second company charges $10.50 rental fee for one tube with a charge of $2.00 an hour. For the x hours, the charge of the company is,

10.50+2.00x

Let x is the hour at which the cost of both companies are equal. Thus,

7.50+3.00x=10.50+2.00x

3x-2x=10.5-7.5

x=2.5

Thus, the minimum number of hours which a person need to rent a tube in order for the second company to be a better deal is more than 2.5 hours.

Using sampling concepts, it is found that the sample would not support a valid inference, as both alphabetized and non-alphabetized students should be sampled.

It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.

The school has both alphabetized and non-alphabetized students, and both groups should be sampled for a valid inference to be made. Since only alphabetized students are sampled, the sample would not support a valid inference.

An exponent is the number of times something is multiplied by itself

Answer: (1/5)^2 * x^3

Step-by-step explanation:

or, x°+(2x+17)°(2x+5)°=180°

or, x°+2x°+17°+2x°+5°=180°

or, 5x°+22°=180°

or, 5x°=180°-22°

or, 5x°=158°

or, x°=158/5

or, x°=31.6

now,

(2x+17)°=2*31.6+17=80.2°

(2x+5)°=2*31.6+5=68.2°

The area of the given trapezoid ABCD in the image shown is calculated as: 54 units²

Area of a trapezoid = 1/2(a + b)h.

Given the following:

Area of triangle ACD = 1/2(AD)(CK) = 30 units²

1/2(10)(CK) = 30 units²

5(CK) = 30

CK = 6 units (altitude of trapezoid ABCD)

Area of the trapezoid = 1/2(a + b)h = 1/2(10 + 8)6

Area of the trapezoid = 54 units²

Unit rate

Answer:

1½ miles/day .

Step-by-step explanation:

To find:-

Answer:-

It is given that the crew made 8¼ miles of road in 5½ days . To find the rate of work done , simply divide the total length of road nade by total time taken . That would be , ( rate is represented by "r" . )

[tex]:\implies \sf r = 8\dfrac{1}{4}\div 5\dfrac{1}{2} \ miles/day\\[/tex]

Convert the mixed fraction into improper fraction.

[tex]:\implies \sf r = \dfrac{33}{4}\div \dfrac{11}{2} \ miles/day \\[/tex]

For dividing them , multiply the reciprocal of 11/2 by 33/4 as ,

[tex]:\implies \sf r = \dfrac{33}{4}\times \dfrac{2}{11} \ miles/day\\[/tex]

[tex]:\implies \sf r = \dfrac{3}{2} \ miles/day \\[/tex]

[tex]:\implies \sf \pink{ r = 1\dfrac{1}{2}\ miles/day } \\[/tex]

Hence the unit rate of constructing the road is 1½ miles/day .
