Answers
The mean amount of snow per day is equal to 19 cm snow per day.
How to calculate the mean for the set of data?In Mathematics and Geometry, the mean for this set of data can be calculated by using the following formula:
Mean = [F(x)]/n
For the total amount of snow based on the frequency, we have;
Total amount of snow (s cm), F(x) = 5(8) + 15(10) + 25(7) + 35(2) + 45(3)
Total amount of snow (s cm), F(x) = 40 + 150 + 175 + 70 + 135
Total amount of snow (s cm), F(x) = 570
Now, we can calculate the mean amount of snow as follows;
Mean = 570/30
Mean = 19 cm snow per day.

The perimeter of a rectangle is the sum of the lenths of its four sides. Which expression, where / = length and w= width, does not show the relationship?
Answers
Answer:
Perimeter of a rectangle = 2(L + W)
Step-by-step explanation:
L = length
W = width
In a rectangle, of the four sides, there are two equal length and 2 equal width
Length = 2 sides
Width = 2 sides
perimeter of a rectangle is the sum of the lenths of its four sides.
Perimeter of a rectangle = L + L + W + W
= 2L + 2W
Factorize
= 2(L + W)
Perimeter of a rectangle = 2(L + W)

What’s the value of k ?

Hello!
\(\large\boxed{k = 10^{o}}\)
When given two interior angles and an exterior angle, the sum of the two interior angles is equal to the sum of the exterior angle. Therefore:
m∠YZX + m∠ZXY ≅ m∠MYZ
(4k + 5)° + (6k + 10)° = 115°
Combine like terms:
10k + 15 = 115°
Subtract 15 from both sides:
10k = 100°
Divide both sides by 10:
k = 10°
Answer:
k=10
Step-by-step explanation:
First you would find the missing angle at the top this would be 65 degrees, this means that the 2 other missing angles must total to 115 degrees.
Second you would set the equations equal to 115
4k+5+6k+10=115
Then you would combine the like terms
10k+15=115
next you would subtract the 15 from both sides
10k=100
then you divide by 10
k=10

Compute f′(a) algebraically for the given value of a. f(x)=−7x+5;a=−6
Answers
The f′(a) when a = −6 is -7. This means that the slope of the tangent line of the graph of f(x) at x = -6 is -7.
To compute f′(a) algebraically for the given value of a, we use the following differentiation rule which is known as the Power Rule.
This states that:If f(x) = xn, where n is any real number, then f′(x) = nxⁿ⁻¹This is valid for any value of x.
Therefore, we can differentiate f(x) = −7x + 5 with respect to x using the power rule as follows:
f(x) = −7x + 5
⇒ f′(x) = d/dx (−7x + 5)
⇒ f′(x) = d/dx (−7x) + d/dx(5)
⇒ f′(x) = −7(d/dx(x)) + 0
⇒ f′(x) = −7⋅1 = −7
Hence, the derivative of f(x) with respect to x is -7.Now, we evaluate f′(a) when a = −6 as follows:f′(x) = −7 evaluated at x = −6⇒ f′(−6) = −7
Therefore, f′(a) when a = −6 is -7. This means that the slope of the tangent line of the graph of f(x) at x = -6 is -7.

Use the Triangle Angle Sum Theorem to find the measure of the angle on point C.
(1 point)
Answers
Therefore , the solution of the given problem of triangle comes out to be curve C has a measure of 70 degrees.
What precisely is a triangle?If a polygon has at least one additional segment, it is a hexagon. Its structure is a simple rectangle. Something like this can only be distinguished from a regular triangular form by edges A and B. Euclidean geometry only creates a portion of the cube, despite the precise collinearity of the borders. A triangular has three sides and three angles.
Here,
Sum of Triangle Angles According to a theorem, a triangle's internal angles always add up to 180 degrees.
We are aware that angle B in the trapezoid is 50 degrees and angle A is 60 degrees. As a result, we can apply the Triangle Angle Sum Theorem to determine the size of angle C:
Angle A +Angles B + C = 180 degrees.
With the known numbers substituted, we obtain:
Angle C: 60° + 50°+60° = 180°
By condensing the left half, we obtain:
Angle C = 180-110 degrees
By taking away 110 degrees from each side, we arrive at:
C = 70-degree slope.
As a result, curve C has a measure of 70 degrees.

Denise is using a ladder to clean the outside of her second story windows. The ladder she is using is 24 feet long and she puts the base of the ladder 13 feet away from the house in order to avoid her flower gardens. How high up the side of her house does the ladder reach? Round to the nearest tenth, if necessary.
Answers
The ladder can reach 21.17 feet high up of Denise's house.
Given,
The length of ladder Denise used to clean the outside of her second story windows = 24 feet
The distance between the base of the ladder and house = 13 feet
We have to find the height of the house which the ladder can reach:
For that we can use Pythagorean Theorem.
That is,
Hypotenuse² = Altitude² + Base²
Here,
Hypotenuse is the length of the ladder = 24 feet
Altitude is the height of the house ladder can reach = x
Base is the distance between base of the ladder and house = 13 feet
Therefore,
24² = x² + 13²
576 = x² + 169
x² = 576 - 169
x² = 407
x = \(\sqrt{407}\)
x = 21.17
That is, the ladder can reach 21.17 feet high up of Denise's house

If The Statement Is True, Prove It. If The Statement Is False, Provide A Counterexample: (A) Let U,V∈V(G) Be Distinct. The Union Of The Edge Sets Of Two Different U, V-Walks Must Contain A Cycle. (B) Let U,V∈V(G) Be Distinct. The Union Of The Edge Sets Of Two Different U, V-Paths Must Contain A Cycle.
Answers
(A) The statement is true. The union of the edge sets of two different U, V-walks must contain a cycle. (B) The statement is false. The union of the edge sets of two different U, V-paths does not necessarily contain a cycle.
(A) The statement is true. If we have two different U, V-walks in a graph, the union of their edge sets will always contain a cycle. This is because a walk is a sequence of vertices and edges that allows revisiting vertices and reusing edges. By combining two different U, V-walks, we are essentially creating a closed loop or a cycle within the graph.
(B) The statement is false. The union of the edge sets of two different U, V-paths does not necessarily contain a cycle. A path is a sequence of vertices and edges where no vertex or edge is repeated. It allows traversing through the graph without revisiting any vertex or reusing any edge. If we combine two different U, V-paths, they may simply merge and extend the overall path without forming a cycle.
To illustrate this, consider a simple graph with three vertices A, B, and C, where there is a direct edge from A to B and another direct edge from B to C. If we consider two different U, V-paths from A to C, say A-B-C and A-C, their union (A-B-C-A-C) does not form a cycle. It is a connected path from A to C without any repeated edges or vertices.

What is a mixed number and how is it different from an improper fraction?A mixed number is a combination of a whole number and a fraction. For example, 3 1/2 is a mixed number. It is different from an improper fraction, which is a fraction where the numerator is greater than or equal to the denominator. For example, 7/4 is an improper fraction.
How do you convert a mixed number to an improper fraction?To convert a mixed number to an improper fraction, you must first multiply the whole number by the denominator of the fraction. Then add the result to the numerator. Finally, place the sum over the denominator. For example, to convert 3 1/2 to an improper fraction, you would first multiply 3 by 2 (the denominator of the fraction 1/2) to get 6, then add 1 (the numerator of the fraction 1/2) to get 7. So 3 1/2 is equivalent to 7/2 as an improper fraction.
So to find out the fraction of a whole pizza that each person gets out of the different remaining pizzas, first we need to all the remaining pizzas as shown below,
3/4 of pepperoni + 5/8 of cheese + 11/12 of sausage = 55/24
Now to equally divide this into 5 person, we need to divide this fraction by 5,
i.e 55/(24*5) = 11/24
Therefore, each person gets 11/24 of the whole pizza.
