STEP-BY-STEP EXPLANATION:
We have the following data:
[tex]2,4,5,5,7,7,8,8,8,12[/tex]The median is the data value that separates the upper half of a data set from the lower half. Therefore:
In this case, being even, the two data are half, but since the value is the same, that is, 7, the median is equal to 7.
The interpretation of this value is in the middle of the 10 days (days 5 and 6), 7 would be the number of cars in a town given a a speeding ticket.
please can you help me to solve an equation ?Determine whether the statement is true or false : The slope of the line y = 1 is zero
The given line equation is y=1.
The general form of the line equation is
[tex]y=mx+b[/tex]Comparing this equation with y=1, we get
[tex]mx+b=1[/tex][tex]mx+b=(0)x+1[/tex]Compare coefficient of x and constant term, we get
[tex]m=0\text{ and b=1}[/tex]Here m=0 is the slope of the line y=1.
Hence the slope of the line y = 1 is zero.
This statement is true.
Evaluate the expression a-5 -b, when a= 10 and b=4

Based on the conversion rate between kilometers and miles, the data to complete the table is:
8 miles : 12.88 kilometers 0.93 miles : 1.5 kilometers 5.58 miles : 9 kilometers 3.1 miles : 4.991 kilometersHow to convert miles to kilometers?For every given mile, there will be 1.61 kilometers. To convert miles to kilometers therefore, you have to multiply the number of miles by the number of kilometers in a mile.
If given 8 miles, the number of kilometers is:
= 8 x 1.61
= 12.88 kilometers
If given 3.1 miles, the number of kilometers is:
= 3.1 x 1.61
= 4.991 kilometers
If given 1.5 kilometers, then the number in miles is:
= 1.5 x 0.62
= 0.93 miles
If given 9 kilometers, then the number in miles is:
= 9 x 0.62
= 5.58 miles

Find the value of X. If ur answer is not an integer
Answer: x = (5√2)/2
The last option
Explanation:
The given triangle is a right triangle. Taking angle 45 as the reference angle,
hypotenuse = 5
opposite side = x
We would find x by applying the sine trigonometric ratio which is expressed as
sin θ = opposite side/hypotenuse
By substituting the given values into the equation,
sin45 = x/5
Recall,

Answer:
y = x-13
Step-by-step explanation:
So this question asks for two numbers. Let's call them x and y.
Since we know that x is larger than y, and the difference between them is 13, x must be greater than y by 13. So, x = y + 13
x = y + 13 isn't what the question is asking for though, so we have to isolate y to make one side contain only x and numbers. To do that, subtract both sides by 13 to get:
x - 13 = y
rearrange:
y = x - 13

Write the slope-intercept form equation for a line that contains point (0, 5) and has a slope of 5/4
The slope-intercept form equation for a line that contains point (0, 5) and has a slope of 5/4 is y = (5/4)x + 5
In this question, we have been given a point (0, 5) and a slope 5/4
We need to write the slope-intercept form equation for a line that contains point (0, 5) and has a slope of 5/4
Using the formula for the point-slope form equation of a line:
(y - y1) = m(x - x1)
y - 5 = (5/4)(x - 0)
y - 5 = (5/4)x
y = (5/4)x + 5
which is slope-intercept form of line.
here slope = 5/4 and y-intercept = 5
Therefore, the slope-intercept form equation for a line that contains point (0, 5) and has a slope of 5/4 is y = (5/4)x + 5

The sum of the length around a square is known as the perimeter thus the possible length of each side of the chicken pen assuming it to be square is 12.5 feet.
What is the perimeter?Perimeter is the addition of an external measure of sides it will always positive.
A perimeter is a length and has a degree of the unit as one.
Perimeter of square = side + side + side + side
Let's assume the chicken pen to the square in order to find the length of each side.
Now since fencing is fitted around the sides so it will be the same as the perimeter of the square.
Perimeter of square = 4 × side
4 × side = 50
Side = 50/4 = 12.5 feet.

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
The first step must be to convert days to hours. A day is equivalent to the 24 hours.
1 day = 24 hours
24 x 7 = 168 hours
The second step must be to convert minutes to hours,
60 minutes = 1 hour

sin ( 2π + ( x - π/6))
sin(2π + Ф ) = sin Ф
So
sin( x - π/ 6)
Formula :
sin(A -B) = sin A cos B - cos A sin B
sin( x - π/ 6)
sin x cos π/6 - cos x sin π/6
con π/6 = √3/2 and sin π/6 = 1/2

[tex]\begin{gathered} 2\frac{3}{10}=\frac{23}{10} \\ \text{The proportion is} \\ \frac{270}{18}=\frac{x}{\frac{23}{10}}\rightarrow\frac{270}{18}=\frac{10x}{23} \end{gathered}[/tex]solving for x:

A boat heading out to sea starts out at Point AA, at a horizontal distance of 1035 feet from a lighthouse/the shore. From that point, the boat’s crew measures the angle of elevation to the lighthouse’s beacon-light from that point to be 8^{\circ} ∘ . At some later time, the crew measures the angle of elevation from point BB to be 5^{\circ} ∘ . Find the distance from point AA to point BB. Round your answer to the nearest foot if necessary.
The angle of elevation reduces. The distance between points A and B is roughly 1,269.9 ft.
The distance between point A and the lighthouse is 968 feet.
The angle of elevation from point A to the lighthouse is 7 degrees.
Elevation angle from point B to the lighthouse = 3°
The distance between points A and B.
tan 7° = Height of the sea / 968 feet
tan(7°) 968 feet 118.86 feet = height to the lighthouse
We have from point B;
tan 3° = 118.86 / Horizontal distance from B to HL
Therefore;
Horizontal distance from LH to boat = 118.6 / tan 30° = 2237.9 = feet
Therefore;
D is the distance between A and B.
D = Horizontal distance between B and LH - Horizontal distance between A and LH
A to B distance = 2237.9 feet − 968 feet 1269.9 feet
The distance between points A and B is 1,269.9 ft.

The following statement "A supply shock is a sudden shortage of a good" is true.
A supply shock is an unexpected incident that abruptly affects the supply of a product or commodity, resulting in an unanticipated change in price. Supply shocks can be negative, resulting in a fall in supply, or positive, resulting in an increase in supply.
Assuming that aggregate demand remains constant, a negative (or unfavorable) supply shock causes a product's price to rise, whereas a positive supply shock causes the price to fall.

What is specific heat capacity ?
In scientific terms, a specific heat capacity is the quantity of heat (J) absorbed by a material every time its temperature goes up 1 K (or 1 °C), given in J/(kg K) or J/(kg °C) per unit mass. formulae for specific heat capacity is given by :

Here the given statement is :
If the temperature of water is between the temperatures of ice and steam, then ice is colder than water and steam is hotter than water.
The above statement is justified below :
The steam exhibit more energy than water at the same temperature that is 100° C. The steam uses the latent heat of vaporization so as to get vaporized and water do not exhibit energy and also, The arrangement of molecules in substances is widely influenced by the state of the matter of the substance. In this way, in solids the molecules have a fix organization and are closely packed due to this, solids have both a defined shape and volume; in liquids the molecules are still close to each other but there is no a defined structure and therefore liquids have a defined volume but not a defined shape; finally, in gases molecules do not follow an orderly arrangement and there is more space between them which makes them not have a define volume or shape.
