Answer:
14.4
Step-by-step explanation:
We can use the pythagorean theorem (a^2 + b^2 = c^2, c being the longest length) to solve this answer.
16^2 - 7^2 = a
256 - 49 = 207.
the square root of 207 is 14.3874...
Rounding to the nearest tenth makes the answer 14.4

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
Answers
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)

X^3 - 100
Answers
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)

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

(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.

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 _______
Answers
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-
