Step-by-step explanation:
Consider sample data with x = 12 and s = 3. (a) Compute the coefficient of variation. % (b) Compute a 75% Chebyshev interval around the sample mean. Lower Limit Upper Limit
Answer: a) 25%
b) 75% Chebyshev interval around the sample mean=(6,18)
Step-by-step explanation:
Given: Sample mean: [tex]\overline{x}=12[/tex]
Sample standard deviation: s= 3
a) Coefficient of variation = [tex]\dfrac{s}{\overline{x}}\times100[/tex]
[tex]\\\\=\dfrac{3}{12}\times100\%=\dfrac{100\%}{4}\\\\=25\%[/tex]
b) According to the Chebychev's theorem,
75% of the population lies within 2 standard deviations from the sample mean.
i.e. 75% Chebyshev interval around the sample mean. = [tex](\overline{x}-2s,\ \overline{x}+2s)[/tex]
[tex]=(12-2(3),\ 12+2(3))\\\\=(6, 18)[/tex]
Hence, the 75% Chebyshev interval around the sample mean=(6,18)

3 1/4 equals 1/2+ W
Hi there!
1.Simplifly each terms:
[tex]3\frac{1}{4}= 3\frac{1}{4}[/tex]
[tex]\frac{1}{2}=\frac{2}{4}[/tex]
2.Convert the term into mixed number:
[tex]3\frac{1}{4}=4+4+4+1=\frac{13}{4}[/tex]
3.Subtract both terms:
[tex]\frac{13}{4}-\frac{2}{4}=\frac{11}{4}[/tex]
4.SimpIifly the fraction term:
[tex]\frac{11}{4}=2\frac{3}{4}[/tex]
This means W=2 3/4..
Rewrite the system of equations in slope intercept form
Y - 5 = -4x
3y - 9 = -6x
The slope-intercept form of the first equation is _______
The slope intercept form of the second equation is _______
Answer:
✔ y = –4x + 5
✔ y = –2x + 3
Step-by-step explanation:
We can write -
The slope-intercept form of the first equation is y = - 4x + 5.The slope intercept form of the second equation is y = - 2x + 3.What is the general equation of a Straight line?
The general equation of a straight line in slope intercept form -
y = mx + c
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
Other possible equations of lines are -
(y - y₁) = m(x - x₁) {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁) {Two point - slope form}x/a + y/b = 1 {intercept form}x cos(β) + y sin(β) = L {Normal form}We have the given system of equations as -
y - 5 = - 4x
3y - 9 = - 6x
The given system of equations is -
y - 5 = - 4x
3y - 9 = - 6x
Now -
y - 5 = - 4x
y = - 4x + 5
and
3y - 9 = - 6x
3y = - 6x + 9
y = (-6/3)x + (9/3)
y = - 2x + 3
So, we can write -
The slope-intercept form of the first equation is y = - 4x + 5.
The slope intercept form of the second equation is y = - 2x + 3.
Therefore, we can write -
The slope-intercept form of the first equation is y = - 4x + 5.The slope intercept form of the second equation is y = - 2x + 3.To solve more questions on straight lines, visit the link below-

What is The difference between 3 7/10 and 2 2/5
Answer:
1 3/10
Step-by-step explanation:
3 7/10 - 2 2/5 =
3 7/10 - 2 4/10 =
1 3/10
Answer:
1 3/10
Step-by-step explanation:
Change the denominator of 2 2/5 to 10 to match denominators by multiplying 2 (numerator and denominator)
New equation: 3 7/10 - 2 4/10 = 1 3/10

Rotate left
(counterclockwise) 90°
Answer:
Draw it like it would be sideways, or if the image you see turned to the left, on its side.
Step-by-step explanation:
Below is an example of it turning. Your shape is already on the center point, so it won't be moving along the X-axis and the center point can stay where it is. the shortest side of it should be facing the left side of your paper.

Answer:
Answer vary:
(a)
*Laila is not wearing tennis shoes.
*It is not the case that Laila is wearing tennis shoes.
(b)
*Jassim is in Germany
Step-by-step explanation:
honestly in my opinion that’s my answer. to be honest either could be wrong but I’m fairly confident in part a but b I’m sorta confident.
(a) what you need to do is focus on the word negations and then you’ll see easily what the answers are. and that’s how I got the answers I got.
meaning of negations : the contradiction or denial of something
(b) so on part b your looking for the conclusion of the sentence and as the sentence explains “If Jassim’s spouse is happy, then Jassim is in Germany.” and for me I came to the conclusion of that answer.

Fully factorise
X^3 - 100
Answer:
(x-10)(x²+10x+100)
Step-by-step explanation:
Given the expression
X^3 - 100
This ca also be expressed as;
X^3 - 100 = X³ - 10³
a³-b³ = (a-b)(a²+b²+ab)
Substitute a = x and b = 10
X³ - 10³ = (x-10)(x²+10²+10x)
X³ - 10³ = (x-10)(x²+10x+100)
Hence the factored form is (x-10)(x²+10x+100)

fatima paid for 5 pallets of grass to be deliverd.
each pallet of grass cost $129.95.
fatima paid $76.20 for delivery.
what is the total amount fatima paid?
pls help
Answer:
$725.95Step-by-step explanation:
Given
Cost of each pallet = $129.95Number of pallets = 5Delivery cost = $76.20Total cost is:
5*$129.95 + $76.20 = $725.95If -6x+12=0 and 4y + 5=9, what is the value of ×+y
Answer:
x=2 y=1 x+y= 2+1=3 3 is the value of x+y
Step-by-step explanation:
Answer:
X=2, Y=1
X+Y=3
Step-by-step explanation:
-6x+12=0. first subtract 12 from each side
-6x=-12 now divide both sides by -6
X=2
4y+5=9. subtract 5 from each side
4y=4 divide both sides by 4
Y=1
2+1=3
I need the answer to this plzzzz
help please!! i dont understand geometry
Answer:
116
Step-by-step explanation:
so to find angle bcs we need to find x and to find x we need to create an equation. 160= angle scd +anglebcs so we do 180=3x+17+12x+8 and solve for x
160=3x+17+12x+8
step 1 combine like terms
160=15x+25
step 2 subtract 25 from each side
135=15x
step 3 divide each side by 15
9=x
then we plug in 9 to 12x+8 and get 116
