If the surface area for the coloured tile is 286cm², find the
value of x.
pls hlp（-""-；)
Answer:
x=8.72389
Step-by-step explanation:
first you make every number 10 times larger
25*10, 48*10, etc etc
you find that you have 12x
the difference between the two surfaces is
120000 (250*480)- 28600= 91400
12x²+20=91400
12x²=91400-20
12x²= 91380
x²=91380/ 12
x²= 7615
x= √7615
x= 87.2389
and since we had made everything 10 times bigger
x=8.72389

If a number fits into the integer, whole number, and natural number categories, where is it placed on the Venn Diagram? Why? PLEASE HELP I NEED HELP ASAP!! I WILL GIVE BRAINLIEST OR WHATEVER
Answer:
The numbers would be placed inside of natural numbers
Step-by-step explanation:
Such number would be placed inside natural numbers.
Integers are whole numbers and their opposites. This means that an integer can be a negative number.
Whole numbers are counting numbers, including Zero and excluding negative numbers. Therefore whole numbers are greater than or equal to 0
Natural numbers are counting numbers excluding Zero and Negative numbers.
From the above definitions, we can agree that natural numbers exists in whole numbers and also exists in integers, but neither of the two exists in natural numbers.
We can then say that
Natural numbers is a subset of whole numbers which is a subset of integers.
Natural numbers < Whole numbers < Integers.

Answer/Step-by-step Explanation:
a. Order the marks scored by James from the least to the largest:
11, 12, 13, 13, 16, 17, 17, 18, 19, 19, 20
To find the interquartile range for James Marks, first find the median, Q1, and then Q3.
The median is the middle value, which is the 6th value in the data set.
11, 12, 13, 13, 16, [17], 17, 18, 19, 19, 20
The median = 17
The Q1 is the middle value from the median to your left, while Q3 is the middle value from the median to the right.
11, 12, (13), 13, 16, [17], 17, 18, (19), 19, 20
Q1 = 13
Q3 = 19
Interquartile range (IQR) = [tex] Q_3 - Q_1 = 19 - 13 = 6 [/tex]
b. Sunil has a median score of 17, which is the same has that of James, however, the interquartile range value for that of Sunil is higher (8) than that of James (6).
The higher the interquartile range, the much variation there is in a set of data. Which can imply inconsistency.
Therefore, James has more consistent marks because his marks has lesser variation.
c. The new marks of the tests which are 16, 20, 18, and 10, would not change the initial median score. This is because, 10 and 16 would fall under the initial median value of 17, while 18 and 20 would fall above the median value of 17. The data set would still be divided into 2, with 17 still being the median.
Therefore, the new median is 17.

A ball is thrown vertically upward. After t seconds, its height h, in feet, is given by the function LaTeX: h\left(t\right)=-16t^2+64th ( t ) = − 16 t 2 + 64 t. How many seconds will it take the ball to reach its maximum height?
Answer:
The time it will take for the ball to reach maximum height of 64 feet is 2 seconds
Step-by-step explanation:
The given equation for the height, h, in feet the ball reaches is given by the function;
h(t) = -16·t² + 64·t
To reach maximum height, [tex]h_{max}[/tex], we have;
At [tex]h_{max}[/tex], we have;
[tex]\dfrac{\mathrm{d} h}{\mathrm{d} t} = 0[/tex]
[tex]\dfrac{\mathrm{d} \left (-16\cdot t^{2} + 64\cdot t \right )}{\mathrm{d} t} = 0[/tex]
Which gives;
64 -32·t = 0
64 = 32·t
t = 64/32 = 2 seconds
Therefore, it will take 2 seconds for the ball to reach maximum height
The maximum height reached is given as follows;
h(2) = -16×2² + 64×2 = 64 feet
The time it will take for the ball to reach maximum height of 64 feet is 2 seconds.

Answer: Hi!
To solve this equation, we need to isolate the x. To do this, we will use inverse operations.
The inverse operation for multiplication is division (3 is being multiplied by x,) so we will divide 3 on both sides:
3x/3 = x
21/3 = 7
Our equation now looks like this:
x = 7
You have nothing left to simplify, so you're done!

We're adding n and m onto k to get P. Undo these operations to isolate k. So we subtract m from both sides
P = k+n+m
P-m = k+n+m-m
P-m = k+n
and we subtract n from both sides
P-m = k+n
P-m-n = k+n-n

A volleyball of radius 13 inches fits exactly in a cylinder with the same radius. A sphere with a radius of 13 inches is inside of a cylinder with a radius of 13 inches. The cylinder has a height of 26 inches. Inside the container there is empty space not taken up by the volleyball. What is the volume of that empty space? Use 3.14 for π and round the answer to the nearest cubic inch. 3,067 in.3 4,599 in.3 13,797 in.3 22,995 in.3
Answer:
B: 4,599 inches
Step-by-step explanation:
The volume of the empty space in cylindrical container is V = 4,599 inches³
What is a Cylinder?A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder. The volume of a cylinder is
Volume of Cylinder = πr²h
Surface area of cylinder = 2πr ( r + h )
where r is the radius of the cylinder
h is the height of the cylinder
Given data ,
Let the radius of the sphere be r₁ = 13 inches
So , the volume of the sphere V₁ = ( 4/3 )πr³
V₁ = ( 4/3 ) ( 3.14 ) ( 13 )³
V₁ = 9,198.106 inches³
Let the radius of the cylinder be r₂ = 13 inches
Let the height of the cylinder be h = 26 inches
So , Volume of Cylinder = πr²h
V₂ = 3.14 ( 13 )² x 26
V₂ = 13,797.16 inches³
So , the volume of the empty space V = V₂ - V₁
V = 13,797.16 inches³ - 9,198.106 inches³
V = 4,599 inches³
Hence , the volume of empty space is 4,599 inches³

Los 75 postulantes que fueron aceptados tuvieron notas desde 16 hasta a 20. Si el grupo se hubiera desempeñado de modo homogéneo y hubieran tenido todos la misma nota, ¿cuál sería esa nota? 2. Si los estudiantes se agrupan según notas, ¿cuántos grupos se forman? 3. ¿Qué notas tendrían los estudiantes del grupo más grande? 4. Si los estudiantes se ordenan en fila según notas, ¿qué nota tiene el del medio?
Answer:
Tenemos 75 postulantes, y sus notas están en el rango desde 16 hasta 20.
1) si el grupo es homogéneo y todos tienen la misma nota, entonces todos van a tener la nota media en el rango (16, 20)
Para encontrar esta nota calculamos la suma entre ambos extremos y lo dividimos por 2.
Media = (16 + 20)/2 = 36/2 = 18
La nota sería 18.
2) entre 16 y 20 tenemos:
16, 17, 18, 19 y 20
tenemos 5 notas distintas, entonces si agrupamos a los estudiantes por nota, tendríamos 5 grupos.
3) En una distribución normal, el grupo mas grande debería coincidir con la media del intervalo. Ya sabemos que la media es 18, entonces es esperable que la nota del grupo mas grande sea 18.
4) Si los estudiantes se ordenan en fila según notas tendríamos:
Fila con nota 16
fila con nota 17
fila con nota 18
fila con nota 19
fila con nota 20
Podemos ver que la fila del medio es el grupo con nota de 18
Chicken eggs can be categorized as large if they weigh at least 2 ounces. Clare weighs 48 large eggs and finds that they have a mean weight of 2.1 ounces and a mean absolute deviation of 0.08 ounces. Interpret 0.08 ounces in this situation.
Answer:
0.08 ounces is interpreted as the Mean Absolute Deviation and this means that
the various weights of each of the 48 eggs deviates from the mean of the egg (2.1 ounces)by 0.08 ounces.
Step-by-step explanation:
Mean Absolute Deviation of a data set is defined as the distance or the deviation between a given data set and the calculated mean.
Mean Absolute Deviation tells us about how much a data set varies from it's mean.
From the above question, we are told that after weighing 48 eggs we have a mean of 2.1 ounces and mean deviation of 0.08 ounces
Therefore this means that the various weights of each of the 48 eggs deviates from the mean of the egg (2.1 ounces)by 0.08 ounces
