Answers
According to Mrs. Wendell 's histogram (shown below), 25% of her cows weigh between 800 and 1199 pounds.
What exactly is a histogram, and why is it useful?A popular charting tool is a histogram. On an interval scale, it is used to describe either discrete or continuous data. It is widely used to show the key properties of distribution of the data in an easy-to-understand fashion.
How do you interpret a histogram?Examine the histogram to see if it shows a normal distribution. Once you've plotted all of the frequencies here on the histogram, it will take on a shape. If the shape resembles a bell curve, it indicates that perhaps the frequencies are evenly distributed. A peak would appear on the histogram.
Briefing:Ms. Wendell sells 25% of her her cows. While purchasing a cow, it is important to remember that weight is an important factor. While there may be some exceptions, the majority of cows sold in the United States weigh between 800 and 1200 pounds.
So, if your farm falls within this range, it would be wise to consider buying a cow from Mrs. Wendell .
Additionally, based on these numbers alone, it would make sense for you to purchase one or more cattle from Mrs. Wendell.
Therefore,
according to Mrs. Wendell 's histogram (shown below), 25% of her cows weigh between 800 and 1199 pounds.

Which inequality is represented by the graph?
Answers
Answer:
Step-by-step explanation:
x < 0
Answer : x is less than or equal to 0
First, the direction of the number line in the graph is the negative number side, so it has to be 0 or less.
If it is less than 0, the dot that starts at the point 0 must have a hollowed out part in the middle. If it is 0 or less, the dot that starts at the point 0 is completely filled with no hollowed middle part.
Since the dot is completely blacked out, the answer is the second option.
Find the degree measure of each angle in the triangle
Answers
The degree measure for angle B is 28° and angle D is 62°.
We are given that:
∠ C = 90°
∠ B = ( 2 x + 10 )°
∠ D = ( 5 x + 17 )°
Now, using the angle sum property of a triangle, we get that:
∠B + ∠ C + ∠ D = 180°
Substituting the values:
2 x + 10 + 90 + 5 x + 17 = 180
7 x + 117 = 180
7 x = 63
x = 63 / 7
x = 9
∠ B = ( 2 x + 10 )
∠ B = 2(9) + 10
∠ B = 18 + 10
∠ B = 28°
∠ D = ( 5 x + 17 )
∠ D = 5 (9) + 17
∠ D = 45 + 17
∠ D = 62°
Therefore, the degree measure for angle B is 28° and angle D is 62°.

First - take the first terms of the brackets (so, x and x) and multiply them together: for this example that gives x2.
Outside - take the two outermost terms of the brackets (x and 5) and multiply them together: for this example that gives 5x.
Inside - take the two innermost terms of the brackets (3 and x) and multiply them together: for this example that gives 3x.
Some people may draw lines between terms when doing this (as seen in the diagram above) leaving you with a “crab claw” around the brackets.
Write down everything you have worked out as one long expression:

(a) Find an equation connecting p and q. (b) Find the value of p when q = 72.
Answers
Step-by-step explanation:
this just means
q = k×p
and we need to find k.
the sum of both q values when p = 6 and p = 11 is then
k×6 + k×11 = 51
17k = 51
k = 51/17 = 3
so, our equation is
q = 3p
and when q = 72
72 = 3p
p = 72/3 = 24
find parametric equations and symmetric equations for the line (use the parameter t.) the line through the point (−3,3,−1) and perpendicular to both ⟨1,1,0⟩ and ⟨
Answers
The second vector that's perpendicular to the line we want (call it L) is missing; I'll denote it by ⟨a, b, c⟩.
The cross product of ⟨1, 1, 0⟩ and ⟨a, b, c⟩ is perpendicular to both of these vectors. The direction vector of L will be parallel to this cross product.
Compute the cross product.
⟨1, 1, 0⟩ × ⟨a, b, c⟩ = ⟨1•c - 0•b, 0•a - 1•c, 1•b - 1•a⟩ = ⟨c, -c, b - a⟩
Then the vector equation of L is
L(t) = ⟨c, -c, b - a⟩ t + ⟨-3, 3, -1⟩
As parametric equations, we write
x(t) = ct - 3
y(t) = -ct + 3
z(t) = (b - a) t - 1
Eliminating the parameter above, we get
x + y = (ct - 3) + (-ct + 3) = 0 ⇒ x = -y
and substituting
x = ct - 3 ⇒ t = (x + 3)/c
into z(t), we get
z = (b - a) (x + 3)/c - 1 ⇒ x = c (z + 1)/(b - a) - 3
As symmetric equations, then, we write
x = -y = c (z + 1)/(b - a) - 3

Answer:
What is the amount (to the nearest cent) in the account at the end of three years if the interest rate is 2%? $1,350.68
Step-by-step explanation:
DATA:
Deposits (at beginning of year):
Year 1 = $500
Year 2 = $200
Year 3 = $600
growth factor: z = 1 + r
interest rate is 2% so replace r with 2%. Growth factor equation is now:
z = 1 + 2%
z = 1.02
Year 1 account balance end of year = account balance + growth factor
= $500 + 1.02

What is a dot-product?The dot product, also known as the scalar product, is an algebraic operation that takes two sequences of numbers of equal length (often coordinate vectors) and outputs a single number. The dot product of two vectors' Cartesian coordinates is frequently used in Euclidean geometry. Although other inner products can be defined in Euclidean space, it is frequently referred to as the inner product (or, less frequently, projection product) of Euclidean space (see Inner product space for more).
The sum of the products of the matching entries of the two number sequences is the dot product, according to algebra. B, it is the result of adding the cosine of the angle between the two vectors and the Euclidean magnitudes of the two vectors.
The vectors that make up the triangle must first be located. The vertices are subtracted to achieve this.
QP=(2,0,-4)-(1,-3,-2)=(1,3,-2)
PR=(1,-3,-2)-(6,-2,-5)=(-5,-1,3)
RQ=(6,-2,-5)-(2,0,-4)=(4,-2,-1)
QP.PR = (1, 3, -2).(-5, -1, 3) = -5-3-6= -14
PR.RQ = (-5, -1, 3).(4, -2, -1) = -20+2-3 = -21
RQ.QP = (4, -2, -1).(1, 3, -2) = 4-6+2 = 0
Calculate the dot products to see if these vectors are perpendicular now.
They are perpendicular if the dot product of two vectors equals zero. As you can see, RQ.QP is zero in your triangle, which supports this. Consequently, a right-angled triangle results.

3.1.1. A(-4, 0) B(0, -2) E(4, 0)
3.1.2. k = -16
3.1.3. (-∞, ∞)
3.1.4. [-16, ∞)
3.1.5. [-6, 4]
Step-by-step explanation:
Given functions:
[tex]\begin{cases}f(x)=x^2+k\\g(x)=-2x+8\\h(x)=\dfrac{6}{x-2}+1\end{cases}[/tex]
Question 3.1.1.Points A and B are the x-intercept and y-intercept of function h(x).
Point E is the x-intercept of function g(x).
The x-intercept of function h(x) is when h(x) = 0:
[tex]\begin{aligned}h(x) & = 0\\\implies \dfrac{6}{x-2}+1 & = 0\\\dfrac{6}{x-2} & = -1\\6 & = -1(x-2)\\6 & = -x+2\\4 & = -x\\x & = -4\end{aligned}[/tex]
Therefore, the coordinates of point A are (-4, 0).
The y-intercept of function h(x) is when x = 0:
[tex]\begin{aligned}h(x) & = \dfrac{6}{x-2}+1\\\implies h(0) & = \dfrac{6}{0-2}+1\\ & = -3+1\\& = -2\end{aligned}[/tex]
Therefore, the coordinates of point B are (0, -2).
The x-intercept of function g(x) is when g(x) = 0:
[tex]\begin{aligned}g(x) & = 0\\\implies -2x+8 & = 0\\-2x & = -8\\x & = 4\end{aligned}[/tex]
Therefore, the coordinates of point E are (4, 0).
Question 3.1.2.As function f(x) passes through point C (-6, 20), substitute the point into the equation of the function to find the value of k:
[tex]\begin{aligned}f(-6) & = 20\\\implies (-6)^2 + k & = 20\\36 + k & = 20\\k & = 20 - 36\\k & = -16\end{aligned}[/tex]
Hence, proving that the value of k is -16.
Question 3.1.3.The domain is the set of all possible input values (x-values).
The domain of function f(x) is unrestricted, therefore its domain is:
Solution: -∞ < x < ∞Interval notation: (-∞, ∞)Question 3.1.4.The range is the set of all possible output values (y-values).
The range of function f(x) is restricted, since the minimum point of the parabola is at (0, -16). Therefore its range is:
Solution: f(x) ≥ -16Interval notation: [-16, ∞)Question 3.1.5.[tex]\begin{aligned}g(x) - f(x) & \geq 0\\\implies g(x) &\geq 0+f(x)\\ \implies g(x) & \geq f(x)\end{aligned}[/tex]
Therefore, find the interval for which g(x) is greater than or equal to f(x).
From inspection of the given graph this is between points C and E:

2. The equation of the parallel line is: y = -x + 4
What are the Equations of Parallel and Perpendicular Lines?The equations of two lines that are parallel to each other will have the slope (m), while the equations of two lines that are perpendicular to each other will have slope values that are negative reciprocals of each other.
The slope-intercept form for the equation of a line is, y = mx + b, where b is the y-intercept and m is the slope of the line.
1. The slope (m) of y = x - 4 is 1. The line that is perpendicular to y = x - 4 would have a slope (m) of -1.
Substitute (a, b) = (1, 3) and m = -1 into y - b = m(x - a):
y - 3 = -1(x - 1)
Rewrite in slope-intercept form:
y - 3 = -x + 1
y = -x + 1 + 3
y = -x + 4
2. The slope (m) of y = -x - 4 is -1. The line that is parallel to y = -x - 4 would have a slope (m) of -1.
Substitute (a, b) = (3, 1) and m = -1 into y - b = m(x - a):
y - 1 = -1(x - 3)
Rewrite in slope-intercept form:
y - 1 = -x + 3
y = -x + 3 + 1
y = -x + 4
