What is the mean and median for the length of 20.3 12.5 7.6 13.9 9.2 21.7 7.6 17.5 15.6 14.1
Mean = 14
and Median = 14
Step-by-step explanation:We are given a data set as:
20.3 12.5 7.6 13.9 9.2 21.7 7.6 17.5 15.6 14.1
there are a total of 10 data points.
Now, the mean of these data points is the average of the data set.
i.e.
[tex]\text{Mean}=\dfrac{\text{Sum of data points}}{\text{Number of data points}}[/tex]
i.e.
[tex]\text{Mean}=\dfrac{20.3+12.5+7.6+13.9+9.2+21.7+7.6+17.5+15.6+14.1}{10}\\\\\text{Mean}=\dfrac{140}{10}\\\\\text{Mean}=14[/tex]
We know that median is the central tendency of the data and it always exist in the middle of the data set.
Firstly we arrange the data points in the increasing order as follows:
7.6 7.6 9.2 12.5 13.9 14.1 15.6 17.5 20.3 21.7
Now, we know that the median of the data exist in between 13.9 and 14.1
i.e.
[tex]\text{Median}=\dfrac{13.9+14.1}{2}\\\\\text{Median}=\dfrac{28}{2}\\\\\text{Median}=14[/tex]

A neon atom has 10 protons and 10 electrons. The 10 protons have a charge of +10 and the 10 electrons have a charge of −10 . No other particles in the atom have a charge. What is the sum of the charges in the neon atom?
Answer:
look at the screenshots below! all correct test answers!
Step-by-step explanation:
The sum of the charges in the neon atom is 0 if the neon atom has 10 protons and 10 electrons and the 10 protons have a charge of +10 and the 10 electrons have a charge of −10.
What is a number line?It is defined as the representation of the numbers on a straight line that goes infinitely on both sides.
It is given that:
A neon atom has 10 protons and 10 electrons. The 10 protons have a charge of +10 and the 10 electrons have a charge of −10.
No other particles in the atom have a charge.
Total charge:
= sum of the charge on the electron + sum of the charge of the protons
As we know, the arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
Total charge = +10 + (-10)
Total charge = +10 -10
Total charge = 0
If we plot the above situation on a number line we will get the total charge is zero.
Thus, the sum of the charges in the neon atom is 0 if the neon atom has 10 protons and 10 electrons and the 10 protons have a charge of +10 and the 10 electrons have a charge of −10.

Tasha does not have enough time to play both the games.
Given that, Tasha has 12 minutes. She wants to jump rope for 8 minutes and play tag for 5 minutes.
What is comparison of numbers?Comparing numbers in math is defined as a process or method in which one can determine whether a number is smaller, greater, or equal to another number according to their values.
Now, number of minutes Tasha wants to jump the rope = 8 minutes and play tag = 5 minutes
So, total time = 8+5 =13 minutes
Here, 12 minutes < 13 minutes
Therefore, Tasha does not have enough time to play both the games.

The weight of a small bag of sugar is 2.265 kg. the student is baking cakes for a college scholarship fundraiser. it takes 100 grams of sugar to make one small cake. how many cakes can be made from a single bag of sugar?
The total batches of cupcakes that make with one small bag of sugar would be 22 batches.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
From the question, we are given the following
The t of a small bag of sugar = 2.265 kg = 2265 grams
100g of sugar to make one batch of cupcakes,
100g = 1 batch ---- 1
In order to get the number of batches of cupcakes made with one small bag of sugar,
2265g = x ---- 2
Divide both expressions;
100/2265 = 1/x
100x = 2265
x = 2265/100
x = 22.65 batches
Hence, the batches of cupcakes that make with one small bag of sugar would be 22 batches.

What is the scale factor of 3,6 and 4.5, 9
The scale factor between the numbers (3, 6) and (4.5, 9) is 2, since the second number in each pair is twice as large as the first number.
Explanation:The scale factor is a ratio that describes how to enlarge or reduce the dimensions of an object to create a new object that is similar to the original. To figure out the scale factor between two similar figures, we calculate the ratio of any two corresponding lengths in the figures.
As per the student's question:
For the pair of numbers (3, 6), the scale factor can be calculated by dividing 6 by 3, which gives us a scale factor of 2.For the pair of numbers (4.5, 9), dividing 9 by 4.5 gives us a scale factor of 2 as well.In each case, the corresponding lengths in the second object are twice those in the first, meaning you can multiply the dimensions of the first figure by 2 to get the dimensions of the second figure.

Which is a correct classification for the triangle? equiangular triangle obtuse triangle acute triangle right triangle Triangle with two angles labeled 22 degrees and 63 degrees
Answer:
The triangle is obtuse triangle.
Step-by-step explanation:
Given two angles of triangle labelled as 22° and 63°. we have to classify the triangle.
Let the third angle be x°
By angle sum property of triangle,
22°+63°+x=180°
⇒ 85°+x=180° ⇒ x=95°
An equiangular triangle is a triangle where all interior angles are equal.
An obtuse triangle is a triangle in which one of the angles is obtuse angle.
An acute triangle is a triangle have all three angles acute.
For right triangle one angle must be of 90°.
Hence, one angle of the triangle is 95° which is obtuse i.e greater than 90°
∴ Given triangle is obtuse.
a rectangle has a perimeter,p, length,l, and width,w. which of the following represents l in terms of p and w?
To find the length (l) of a rectangle in terms of the perimeter (p) and width (w), use the formula l = (p - 2w) / 2.
Explanation:To find the length (l) of a rectangle in terms of the perimeter (p) and width (w), we can use the formula for the perimeter of a rectangle, which is given by:
p = 2l + 2w
Now, solve the equation for l by subtracting 2w from both sides:
p - 2w = 2l
Finally, divide both sides by 2:
l = (p - 2w) / 2

Drake lives 7/8 mile from the park. After walking 2/3 of the way to the park, he met Scott. How far had Drake walked when he met Scott?
To find the distance Drake walked, calculate 2/3 of 7/8 mile, which results in 14/24, and simplify this fraction to 7/12 mile. Therefore, Drake walked 7/12 mile when he met Scott.
Drake lives 7/8 mile from the park. To find out how far he walked when he met Scott after walking 2/3 of the way to the park, you need to calculate 2/3 of 7/8 mile. The calculation is as follows:
Distance walked = (2/3) * (7/8)
First, multiply the numerators together: 2 * 7 = 14.
Then, multiply the denominators together: 3 * 8 = 24.
Now, put it together:
Distance walked = 14/24
We can simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 2.
So, 14 / 2 = 7 and 24 / 2 = 12.
Therefore, the simplified fraction is 7/12 mile.
Drake walked 7/12 mile when he met Scott.

How can I rename 82 thousands?
82 thousands can be renamed as 8 ten thousands and 2 thousands, or as 0.082 hundred thousands in the decimal system.
Explanation:Renaming 82 thousands means expressing this amount in another unit of place value. In the standard decimal system, the next unit larger than thousands is ten thousands. The digit in the ten thousands place represents the number of ten thousands in that number. If you have 82 thousands, this equals 8 ten thousands and 2 thousands, because 82 divided by 10 equals 8 with a remainder of 2. Therefore, 82 thousands can be renamed as 8 ten thousands and 2 thousands. Similarly, 82 thousands can also be expressed as 0.082 hundred thousands, as 82 divided by 1000 equals 0.082.
