Answer:
The diameter is 21 cm
Step-by-step explanation:
The formula for the volume of a sphere is V = (4/3)πr³, or (in terms of the diameter) V = (4/3)π(d/2)³. This simplifies to
4πd³ πd³
V = ----------- = -----------
3·8 6
Now equate V = (πd³/6) to 4851 cm³. We must first solve this for d³ and then take the cube root of the result:
πd³ = 4851(6) = 29106.
Dividing this result by π yields 9264.7,
and taking the cube root of this is 21. The diameter is 21 cm
A trader bought 12 shirts for $150 altogether. He sold 11 of them for $20 each and one for $10.
Work out his overall percentage profit or loss,
Answer:
53%
Step-by-step explananation:
how much did he sell them for?
11*20 = 220
220+10 = 230
so he got a total of 230 off of buying 150
percent is difference of original
(230-150)/150
80/150
about 53%
I think this is right

6. You are planning a trip. You can go to Phoenix, Las Vegas, San Diego, or Los Angeles. You can
fly or drive. You can stay 3, 4, or 5 days. How many different trip possibilities are there?
How many different trip possibilities are there?
Answer:
There are 24 different trip possibilities.
Step-by-step explanation:
Here the first thing we need to find is all the individual events, such that each event (or selection) will have a given number of options.
The first event is the selection of the location.
Here the options are: Phoenix, Las Vegas, San Diego, or Los Angeles (4 options)
The second event is the selection of how you go there.
The options are flying or driving (2 options)
The third event is the selection of how many days you will stay there. The options are 3 days, 4 days, and 5 days (3 options).
The total number of different trip possibilities is equal to the product between the number of options for each event.
P = 4*2*3 = 24
There are 24 different trip possibilities.
someone please please help me with this ( a explanation on why you got this answer would be very helpful too) I would really appreciate it
Step-by-step explanation:
Let label this using a triangle.
We are sitting 300 ft away from the building.
We can look up to see the top of building at an angle of 60 degrees. So 60 degrees would be near where we standing at. The other angle of the top triangle would be 30 since that the height of building and the ground horizon is perpendicular to each other so they measure 90 degrees. Using triangle interior theorem, the missing angle would be 30.
We use another triangle since we are looking down.
The height of building and where we sitting at is perpendicular. The angle near we at would measure 15 and the missing angle would be 75.
The triangles both combine to form one triangle. They would form a isoceles triangle.
The most bottom angle of the triangles measure 75 while the angle where we are at of both triangle measure 75. so we have a isoceles triangle.
This means that the hypotenuse of the top triangle is equal to the length of the building.
To find the hypotenuse use 30-60-90 rules,
hypotenuse =twice of most shortest side.
[tex]h = 300 \times 2[/tex]
[tex]h = 600[/tex]
So the length of the building is 600.

The difference between the highest and lowest single game point totals for the MIDDLE HALF of the data is ______ points less for Joe's data than Sam's data. Therefore, the MIDDLE HALF of Joe's single game point totals are less varied than Sam's.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the required data to answer the question are missing.
However, the interpretation of the question is to determine the interquartile range (IQR) of a certain dataset.
Then get the difference between the calculated IQR & Joe's data and also the difference between the calculated IQR & Sam's data
Then, make comparison
To do this, I will use the following assumed datasets.
[tex]Data: 62, 63, 64, 64, 70, 72, 76, 77, 81, 81[/tex]
IQR is calculated as:
[tex]IQR = Q_3 - Q_1[/tex]
[tex]Q_3[/tex] is [tex]the\ median[/tex] of the upper half
[tex]Q_1[/tex] is [tex]the\ median[/tex] of the lower half
For Joe, we have:
[tex]Lower\ half: 62, 63, 64, 64, 70[/tex]
[tex]Upper\ half: 72, 76, 77, 81, 81[/tex]
The median is then calculated as:
[tex]M = \frac{N + 1}{2}[/tex]
For, the lower half:
[tex]Q_1 = \frac{5 + 1}{2} = \frac{6}{2} = 3rd[/tex]
So:
[tex]Q_1 = 64[/tex]
For the upper half:
[tex]Q_3 = \frac{5 + 1}{2} = \frac{6}{2} = 3rd[/tex]
So:
[tex]Q_3 = 77[/tex]
When the same process is applied to Sam's data,
[tex]Q_1 = 52[/tex]
[tex]Q_3 = 58[/tex]
[tex]IQR = Q_3 - Q_1[/tex]
[tex]IQR = 77 - 64[/tex]
[tex]IQR = 13[/tex]
Assume that:
[tex]Joe = 60[/tex]
[tex]Sam = 65[/tex]
[tex]Joe - IQR = 60 - 13 = 47[/tex]
[tex]Sam- IQR = 65- 13 = 52[/tex]
Hence, the IQR is 47 points less for Joe's data than Sam's

How do I complete this chart?
Answer:
Step-by-step explanation:
You would first have to plug in for x, (which is already given). After plugging in for x, you would need to solve the equation to get y.
Once you have both x and y, you will have your (x,y)
For example: (given x value = -5)
[tex]f(x) = -|x - 5| -4\\f(-5) = -|(-5) - 5| - 4\\f(-5) = -|-10| - 4\\f(-5) = -10 - 4\\f(-5) = -14\\f(-5) = y = -14\\\\[/tex]
so:
x = -5
y = -14
( -5, -14)
Find the value of x.

Un huerto escolar tiene una superficie de 4dam2 500m2 y se requiere dividir en seis parcelas rectangulares de igual area ¿ cuantos metros cuadrados tendra cada parcela ?
Answer:
Cada parcela tendrá una extensión de 150 metros cuadrados.
Step-by-step explanation:
De acuerdo con el enunciado el huerto escolar tiene una extensión de 4 decámetros y 500 metros cuadrados.
Tengamos presente que un decámetro es igual a 100 metros cuadrados, entonces el huerto escolar tiene un área total de 900 metros cuadrados. Si dividimos esa área en seis parcelas de igual extensión, tenemos que:
[tex]x = \frac{900\,m^{2}}{6}[/tex]
[tex]x = 150\,m^{2}[/tex]
Cada parcela tendrá una extensión de 150 metros cuadrados.

At a basketball game, a team made 55 successful shots. They were a combination of 1- and 2-point shots. The team scored 92 points in all. Write and solve a system of equations to find the number of each type of shot.
There were 18 one point shots and 37 two point shots.
Step-by-step explanation:
Let the number of one point shots be x and the number of two point shots be y .
So we have the system:
x + y = 55
x + 2y = 92
Subtract the first equation from the second, we get:
0 + y = 92 - 55 = 37.
y = 37.
From equation 1 we have x = 55 - y
therefore x = 55 - 37 = 18.

Answer:
1
Step-by-step explanation:
Because, The mode is the value that appears most often in a set of data values. If X is a discrete random variable, the mode is the value x at which the probability mass function takes its maximum value. In other words, it is the value that is most likely to be sampled.
