What is the median from the following set of data:1,2,3,3,3,8,8,11,15?
Answer:
3
Step-by-step explanation:
The median is the # in the middle, and since 3 is used 3 times, it´s the most used # and is in the middle
[tex]\huge{\boxed{3}}[/tex]
The median is the middle number when the numbers are arranged least to greatest, which they already are.
Take numbers away two at a time, one from the front and one from the back.
1,2,3,3,3,8,8,11,15
2,3,3,3,8,8,11
3,3,3,8,8
3,3,8
This means that the median is [tex]\boxed{3}[/tex]

The ratio of side lengths for two similar cubes is 2/5
Show your work or explain how you got your answers.
a.The perimeter of one face of the smaller cube compared to the perimeter of one face of the larger cube
Answer:
The perimeter of one face of the smaller cube compared to the perimeter of one face of the larger cube is [tex]\frac{2}{5}[/tex]
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
and
If two figures are similar, then the ratio of its perimeters is equal to the scale factor
Let
z-----> the scale factor
x-----> the perimeter of the smaller cube
y ----> the perimeter of the larger cube
[tex]z=\frac{x}{y}[/tex]
in this problem we have
[tex]z=\frac{2}{5}[/tex] ----> scale factor
substitute
[tex]\frac{x}{y}=\frac{2}{5}[/tex]
the difference between 4 632 and 20 000 is what number?
u just divide 4,632 by 20,000
Answer:
-15368
Step-by-step explanation:
the ratio of the number of men to the number of women on a bus was 2:3 at a bus stop. 4 women got off and the ratio became 4:5. 1 How many men were on the bus? b. How many women were on the bus in the end?
Answer:
At the beginning
16 men and 24 women
In the end
16 men and 20 women
Step-by-step explanation:
Call x the number of men on the bus and call y the number of women on the bus.
We know that the initial ratio between men and women is 2: 3
And the final ratio is 4: 5
So
[tex]\frac{x}{y}=\frac{2}{3}\\\\y = \frac{3}{2}x[/tex] (1)
After the 4 women are down, the proportion is:
[tex]\frac{x}{y-4}=\frac{4}{5}\\\\y-4 = \frac{5}{4}x\\\\y= \frac{5}{4}x +4[/tex] (2)
Substitute the value of y in the first equation and solve for x
[tex]\frac{5}{4}x +4=\frac{3}{2}x\\\\-\frac{1}{4}x=-4\\\\x=16\ men[/tex]
Now solve for y.
[tex]y = \frac{3}{2}(16)\\\\y=24\ women[/tex]
Then at the end there were
[tex]y = 24-4 = 20[/tex] women

Solve by using Pythagoras triangle concept
x^2 + 15^2 = (9+x)^2
x^2 + 225 = 81 + 18x + x^2
x^2 - x^2 + 225 - 81 = 18x
144 = 18x
144/18 = x
x = 8
Answer:
x = 8
Step-by-step explanation:
Since the triangle is right use Pythagoras' theorem
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
(x + 9)² = x² + 15² ← expand factor on left side
x² + 18x + 81 = x² + 225 ( subtract x² from both sides )
18x + 81 = 225 ( subtract 81 from both sides )
18x = 144 ( divide both sides by 18 )
x = 8

Actually, none of the posted possible answers is correct. The slope of the horizontal line is zero, whereas the slope of the given equation is 8. There is no number which, when multiplied by 0, results in a non-zero product.
However, if we are ADDING instead of multiplying, then the correct number is 8, because 0 + 8 = 8.
If 38 12-m – 82m, what is the value of m?
Answer:
[tex]m=-\frac{26}{83}[/tex]
Step-by-step explanation:
Since you are asking for the value of [tex]m[/tex], it is reasonable to assume that we are dealing with an equation here and you forgot to type the equal sign. Given that, I assume our equality is [tex]38=12-m-82m[/tex]. Let's solve it step-by-step:
Step 1. Subtract 12 from both sides of the equation
[tex]38-12=12-12-m-82m[/tex]
[tex]26=-m-82m[/tex]
Step 2. Combine like terms (m terms)
[tex]26=(-1-82)m[/tex]
[tex]26=-83m[/tex]
Step 3. Using the reflexive property of equality: if a = b, then b = a
[tex]26=-83m[/tex]
[tex]-83m=26[/tex]
Step 4. Divide both sides of the equation by -83
[tex]\frac{-83m}{-83} =\frac{26}{-83}[/tex]
[tex]m=-\frac{26}{83}[/tex]
We can conclude that the value of m is [tex]-\frac{26}{83}[/tex].

Ms. Chloe has 5 cups of popcorn, which she is serving as a snack to a group of children. Each serving is 1/4 of a cup. How many children can get a serving of popcorn as a snack?
20 children can get a serving of popcorn
Since each serving is 1/4 of a cup, each cup can provide for 4 children. Since there are 5 total cups, multiplying 5 by 4 will give you 20.
The answer is 20 because first you have to set up a division equation. It would be 5 divided by 1/4.You can’t divid with a fraction so you must change it into a multiplication sentence. The new equation would now be 5 times 4/1 and the answer would be 20. Therefore, Ms.Chloe can freed 20 children.

A circle has its center at (1,4) and a radius of 2 units what is the equation of the circle
Answer: x² + y² - 2x - 8y + 13 = 0
Step-by-step explanation:
the equation of the circle is in the form (x - a)² + (y - b)² = r²
where (a,b) is the center of the circle and r is the radius
hence the equation is
(x - 1)² + (y - 4)² = 2²
x²-2x+1+y²-8y+16= 4
x²+ y² -2x- 8y + 17 =4
x² + y² - 2x - 8y = -13
x² + y² - 2x - 8y + 13 = 0

What is the length of each side of the larger square
Answer:
The larger square is 6 cm on a side
Step-by-step explanation:
Let x = the side of square 1
Let y = side of square 2
A= s^2
Area of square 1 = x^2
Area of square 2 = y^2
The total area of both squares = x^2 +y^2 = 45
We know that y = 2x
Substituting in
x^2 + (2x)^2 = 45
x^2 +4x^2 = 45
5x^2 = 45
Divide each side by 5
5x^2/5 = 45/5
x^2 = 9
Take the square root of each side
sqrt(x^2) = sqrt(9)
x = 3
y = 2x = 2(3) = 6
The larger square is 6 cm on a side

Answer:
Final answer is [tex]a_0=-9[/tex]
Step-by-step explanation:
Given equation is [tex]5-a_0=14[/tex]
Now we need to solve the given equation [tex]5-a_0=14[/tex] for the unknownd variable [tex]a_0[/tex] .
We can do that by isolating [tex]a_0[/tex]
To isolate [tex]a_0[/tex], let's subtract 5 from both sides
[tex]5-a_0-5=14-5[/tex]
[tex]-a_0=9[/tex]
multiply both sides by -1
[tex]-a_0(-1)=9(-1)[/tex]
[tex]a_0=-9[/tex]
Hence final answer is [tex]a_0=-9[/tex]

The length of a rectangle is 45 inches more than the width. The perimeter is 346 inches. Find the length and the width.
Solution:
Perimeter of Rectangle = 346Let Required length of breadth be x
Then, Length of Rectangle = 45 + xNow, We have ;
Perimeter of Rectangle = 2(l+b)Perimeter of Rectangle = 2 ( 45 + x + x346 = 2 ( 45 + 2x )346 = 90 + 4x 346 - 90 = 4x 256 = 4x x = 256 ÷ 4 x = 64 inchesSo, Length of Rectangle = x + 46
Length of Rectangle = 64 + 46
Length of Rectangle = 110 inches
Now, Breadth of Rectangle = 64 inches.
Answer:
Length = 109 inches and width = 64 inches
Step-by-step explanation:
Perimeter = 2(length + width)
Let the width of the rectangle be 'w' inches
Length of the rectangle would be = 45+w inches
2((45+w)+w) = 346
2(45+2w) = 346
90 + 4w = 346
4w = 346 - 90
4w = 256
w = [tex]\frac{256}{4}[/tex]
w = 64 inches
Length = 45 + 64 = 109 inches
Length = 109 inches and width = 64 inches

The point-slope form of the equation of the line that passes through (-9, -2) and (1.3) is y-3=1/2(x-1). What is the slope-intercept form of the equation for this line?
Answer:
y = 1/2x + 5/2
Step-by-step explanation:
y-3=1/2(x-1).
To get from point slope to slope intercept, distribute the slope
y-3 = 1/2 x -1/2
Then add 3 to each side
y-3+3 =1/2 x -1/2 +3
y = 1/2x +2 1/2

A ruler can measure the length to the nearest 0.1 centimeter. Which of these lengths is the most precise measurement the ruler could make of a wire that measures 13.58cm
Answer:
13.6
Step-by-step explanation:
"A ruler can measure the length to the nearest 0.1 centimeter. Which of these lengths is the most precise measurement the ruler could make of a wire that measures 13.58cm"
Down to the nearest .1 centimeter means round to the nearest .1, so the solution is 13.6cm
A ruler that can measure to the nearest 0.1cm would be able to accurately measure a wire of 13.58cm up to 13.5cm. The remaining 0.08cm cannot be measured accurately by this ruler.
Explanation:In this context, the term 'precision' refers to the smallest measurement that can be reliably marked by an instrument. Given that the ruler can measure to the nearest 0.1 centimetre, the most precise measurement the ruler can make is till decimals of one place. Therefore, for a wire measuring 13.58cm, the ruler will be able to precisely measure till 13.5cm. The wire's length of '0.08cm' beyond '13.5cm' cannot be accurately measured with this ruler as it doesn't have markings to measure in this range.
