how do you find a meadian?
Answers
Final answer:
The median is a number that measures the center of the data. To find the median, arrange the data in ascending order and determine the middle value. If the data has an even number of values, the median is the average of the two middle values.
Explanation:
The median is a number that measures the center of the data. It separates the data into two halves, with half the values being smaller or equal to the median and the other half being larger or equal to it. To find the median, you need to arrange the data in ascending order and then determine the middle value.
If the data has an even number of values, the median is the average of the two middle values.
A girl stands 160 cm tall she stands 360 cm away from a lamp post at night her shadow from the light is 90 cm long how high is the lam post
Answers
h1/b1=h2/b2
h1 is the height asked.
b1=360 cm+ 90 cm
b1=450 cm
h2=160 cm
b2=90 cm
2. When you substitute these values into h1/b1=h2/b2, you obtain:
h1/450 cm=160 cm/90 cm
3. Now, you must clear the height "h1". Then, you have:
h1=(160 cm)(450 cm)/90 cm
h1=72000 cm²/90 cm
h1=800 cm
How high is the lamp post?
The answer is: 800 cm
Final answer:
To find the height of the lamppost given the girl's height, distance from the lamp post, and shadow length, set up a proportion to calculate the lamp post's height.
Explanation:
A girl stands 160 cm tall and stands 360 cm away from a lamp post at night. Her shadow from the light is 90 cm long. How high is the lamppost?
Set up a proportion: Lamp post height / Girl's height = Lamp post shadow length / Girl's shadow length.
Substitute the values: Lamp post height / 160 cm = 360 cm / 90 cm.
Solve for the lamp post height: Lamp post height = (360 cm * 160 cm) / 90 cm = 640 cm.

Answers
distance(AA') = √(2^2 + 1^2)

answer
Distance AA' = √5 or = 2.24
Answer with Step-by-step explanation:
As we can see from the graph:
A=(0,0) and A'=(2,1)
Distance between (x1,y1) and (x2,y2) is given by:
[tex]\sqrt{{(x1-x2)}^2+{(y1-y2)}^2}[/tex]
Here (x1,y1)=(0,0) and (x2,y2)=(2,1)
Hence, distance between A and A' is:
[tex]\sqrt{{(0-2)}^2+{(0-1)}^2}[/tex]
= [tex]\sqrt{4+1}[/tex]
= [tex]\sqrt{5}[/tex]
Hence, distance AA'=√5
The speed limit is posted in most areas, but, if not, the ___________ speed limit will be in effect.
Answers
When no specific speed limit is posted, the default speed limit applies. These defaults are set by local or state law and can vary. Drivers must adhere to these limits and drive safely for conditions.
Explanation:In most areas, when specific traffic speed limit signs are not posted, what's known as the default speed limit applies. These default speed limits are not posted on signs and instead are set by local or state law. It's important to stay aware of these limits in different areas, as they can vary. For instance, in many cities, the default speed limit is 25 mph unless otherwise posted. However, it should be noted that these default limits may not protect you from being pulled over if the police deem your speed unsafe for the current conditions. Thus, it's recommended to always drive at a speed that is appropriate for the conditions, even if you are technically within the speed limit.

Hope I helped!
Let me know if you need anything else!
~ Zoe
According to our customary units of miles, 1 mile is equal to 5,280 feet - and 3 feet is a yard. That means, we have to divide 5,280 by 3 to figure out how many yards are in a mile:
5280/3 = 1760
That means that one mile is 1760 yards. But we're not finished yet. It says 1/5 miles, not one mile. Therefore, we take one half of the total distance in yards of a mile and add it to that 1760, because it's 1.5, or 1-and-a-half. Which, in technical terms means "1-plus-a-half".
We have:
1760 + 1760/2 = 1760 + 880 = 2640
Therefore, 1/5 miles, since it's 2640 yards, is greater than the 2500 yards specified in the question.

BQ←→ is not a tangent line because ∠BQA is an acute angle.
Answers
We have a circle A and a line segment BQ is passing through the circle A such that it forms a triangle ABQ.
From the diagram, we have some information about the angles of triangle ΔABQ as follows :-
angle QAB = 36 degrees and angle BAQ = 54 degrees.
We know about the Triangle Sum theorem which states "The sum of all interior angles of any triangle is 180 degrees".
We can use this theorem to find the third angle of the triangle ΔABQ.
∠ABQ + ∠BQA + ∠QAB = 180 degrees
∠ABQ + 54° + 36° = 180°
∠ABQ + 90° = 180°
∠ABQ = 180° - 90°
∠ABQ = 90 degrees
If any line makes a right angle with the radius of any circle, then this line must be a tangent to that circle.
So, BQ would be a tangent line because angle ∠ABQ = 90 degrees. Hence, option A is correct.

A pair of diamond earrings has been marked up 50% and is now selling for $198.00. How much were the earrings before the mark-up?
Answers
Final answer:
The original price of the diamond earrings before a 50% markup that led to a final selling price of $198.00 was $132.00.
Explanation:
The question asks us to find the original price of the diamond earrings before a 50% markup that resulted in a final selling price of $198.00. To solve this, we use the markup formula, which is Final Price = (Original Price) × (1 + Markup Percentage). Here, the Final Price is $198.00 and the Markup Percentage is 50%, or 0.50 when expressed as a decimal.
First, we rearrange our formula to solve for the Original Price:
Original Price = Final Price ÷ (1 + Markup Percentage). Plugging in the given values, we have: Original Price = $198.00 ÷ (1 + 0.50) = $198.00 ÷ 1.50.
Doing the computation: Original Price = $132.00. Therefore, the earrings were priced at $132.00 before the 50% markup.

The graph of the function f(x) = ax2 + bx +c (where a, b, and c are real and nonzero) has two x-intercepts. Explain how to find the other x-intercept if one x-intercept is at (-b/a2 +3,0)
Answers
The method to find the other x-intercept for the function f(x) = ax² + bx + c is given in the explanation below the answer.
The other x-intercept is; ((-b/2a - 3), 0)
We are given the equation of the function;
f(x) = ax² + bx + c
where a, b and c are real numbers and non - zero
Now, this is a quadratic equation that has 2 roots and it means there will be two x-intercepts.
Also, in quadratic equations, the formula to find the x-coordinate of the line of symmetry of the graph is;
x = -b/2a
The line of symmetry divides the graph curve into 2 equal parts at the vertex. This means the two x - intercepts will be the same distance from the x-coordinate of the vertex or line of symmetry but on opposite sides.
Thus, if one x-intercept is at ((-b/2a + 3), 0), then the other coordinate using the line of symmetry reason above is; ((-b/2a - 3), 0)
