The snow that will be gotten daily of the line plot is redistributed equally will be 1/2.
What is a line plot?A line plot, also known as a line graph, is a type of graph that displays information as a series of data points connected by straight lines. Line plots are often used to show how a particular variable changes over time or to compare two or more variables.
To create a line plot, you typically need to have a set of data points that represent the variable you want to graph. You then plot each data point on a graph, with the x-axis representing time or some other variable, and the y-axis representing the value of the variable you're graphing.
The snow that will be gotten daily of the line plot is redistributed equally will be:
= (1/8 + 2/8 + 3/8 + 4/8 + 5/8 + 6/8 + 7/8 + 8/8) / 9
= 36/8 / 9

Jon Marc is ordering bark dust for two clients. Each client has a circular flower bed. Jon Marc
knows the radius of one flower bed is 6.5 feet and the diameter of the other is 30 feet. How
many square feet of bark dust should Jon Marc order?
The total area square feet of bark dust should Jon Marc order is 839.1 square feet.
What is area?
The region that an object's shape defines as its area. The area of a figure or any other two-dimensional geometric shape in a plane is how much space it occupies.
Here we know that , area of the circle = [tex]\pi r^2[/tex] square unit.
Now radius of one flower bed = 6.5 feet. Then,
Area of the bed = [tex]3.14\times 6.5^2[/tex] = 132.6 square feet,
Now diameter of another bed = 30 feet then,
Radius = 30/2 = 15 feet. Then
Area of the bed = [tex]3.14\times15^2[/tex] = 706.5 square feet.
Then total square feet of bark dust should Jon Marc order is
=> 132.6 + 706.5 = 839.1 square feet.

The piecewise function for f(x) is f(x) = x - 2, x ≥ 2; -x + 2, x < 2, So the correct answer is option C.
Describe Function?In mathematics, a function is a rule that assigns each element of a set (called the domain) to a unique element of another set (called the range). Functions are a fundamental concept in mathematics and are used to describe relationships between variables, as well as to model and solve a wide range of mathematical problems.
A function is typically denoted using a letter such as "f", and is defined by an equation or formula that specifies how the input (or domain) values are transformed into output (or range) values. For example, the function "f(x) = 2x + 1" assigns each input value "x" to an output value equal to twice the input value plus one.
The absolute value function f(x) = |x - 2| can be written as a piecewise function by separating it into two cases:
Case 1: x - 2 ≥ 0 or x ≥ 2
In this case, the expression inside the absolute value bars becomes x - 2, so f(x) = x - 2.
Case 2: x - 2 < 0 or x < 2
In this case, the expression inside the absolute value bars becomes -(x - 2) = -x + 2, so f(x) = -x + 2.
Therefore, the piecewise function for f(x) is:
f(x) =
x - 2, x ≥ 2
-x + 2, x < 2
So the correct answer is option C.

O Option D
Option B is the most expensive, with a total cost of $240 per month if the patient fills 7 prescriptions per month.
Which option is the most expensive if the patient fills 7 prescriptions each month?To determine which option is the most expensive, we need to calculate the total cost for each option if the patient fills 7 prescriptions per month.
For Option A, the total cost would be:
(7 x $15) + $105 = $210
For Option B, the total cost would be:
(7 x $20) + $100 = $240
For Option C, the total cost would be:
(7 x $10) + $115 = $185
For Option D, the total cost would be:
(7 x $12) + $110 = $194
Therefore, Option B is the most expensive, with a total cost of $240 per month if the patient fills 7 prescriptions per month. The other options are cheaper, with Option C being the least expensive at $185 per month.

After answering the provided question, we can state that Therefore, the parallelograms measure of angle C is 63°.
What is parallelograms?In Euclidean geometry, a parallelogram is a simple quadrilateral with two sets of parallel sides. A parallelogram is a type of quadrilateral in which both sets of opposite sides are parallel and equal. Parallelograms are classified into four types, three of which are unique. The four different shapes are parallelograms, squares, rectangles, and rhombuses. A quadrilateral is a parallelogram when it has two sets of parallel sides. The opposing sides and angles of a parallelogram are both the same length. The interior angles on the same side of the horizontal line are also angles. 360 degrees is the total number of interior angles.
Since ABCD is a parallelogram, opposite angles are congruent. Therefore,
m∠A = m∠C
13x - 41 = 6x + 15
7x = 56
x = 8
m∠C = 6(8) + 15 = 63
Therefore, the measure of angle C is 63°.

A mail-order computer business has four telephone lines. Let X denote the number of lines in use at a specified time. Suppose the pmf of X is as given in the accompanying table.Xp(x)00.11230.25 0.30.35a. Find the cdf F(x) of X. b. Calculate the probability of each of the following events: A = {fewer than two lines are in use},B= {at least two lines are in use}, C= {between one and five lines, inclusive, are in use}.
The probability of each event is: P(A) = 0.34 P(B) = 0.66 P(C) = 0.89
What is Probability ?
Probability can be defined as ratio of number of favourable outcomes and total number of outcomes.
To find the cdf F(x) of X, we can use the following formula:
F(x) = P(X ≤ x) = ∑ P(X = k) for k ≤ x
So we have:
F(0) = P(X ≤ 0) = P(X = 0) = 0.11
F(1) = P(X ≤ 1) = P(X = 0) + P(X = 1) = 0.11 + 0.23 = 0.34
F(2) = P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.11 + 0.23 + 0.25 = 0.59
F(3) = P(X ≤ 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0.11 + 0.23 + 0.25 + 0.3 = 0.89
F(4) = P(X ≤ 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) = 0.11 + 0.23 + 0.25 + 0.3 + 0.35 = 1
So the cdf F(x) of X is:
F(x) = 0 for x < 0
F(x) = 0.11 for 0 ≤ x < 1
F(x) = 0.34 for 1 ≤ x < 2
F(x) = 0.59 for 2 ≤ x < 3
F(x) = 0.89 for 3 ≤ x < 4
F(x) = 1 for x ≥ 4
b. To calculate the probability of the events A = {fewer than two lines are in use}, B = {at least two lines are in use}, C = {between one and five lines, inclusive, are in use}, we can use the cdf F(x) that we just found.
P(A) = P(X < 2) = F(1) = 0.34
P(B) = P(X ≥ 2) = 1 - P(X < 2) = 1 - F(1) = 1 - 0.34 = 0.66
P(C) = P(1 ≤ X ≤ 5) = F(5) - F(0) = 1 - 0.11 = 0.89
Therefore, the probability of each event is: P(A) = 0.34 P(B) = 0.66 P(C) = 0.89

the total area under the normal distribution curve is 0.9632.
How to find total area under the normal distribution curve?
To find the total area under the normal distribution curve, we can use the standard normal distribution table or a calculator with a normal distribution function. We need to find the areas to the left and right of the given z-scores and add them together.
First, we can find the area to the left of z = -2.15 using the standard normal distribution table or a calculator with a normal distribution function. The area to the left of z = -2.15 is the same as the cumulative probability of a standard normal distribution with a z-score of -2.15. Using a standard normal distribution table or a calculator, we find this area to be 0.0158.
Next, we can find the area to the right of z = 1.62 using the standard normal distribution table or a calculator with a normal distribution function. The area to the right of z = 1.62 is the same as the complement of the cumulative probability of a standard normal distribution with a z-score of 1.62. Using a standard normal distribution table or a calculator, we find the complement to be 0.0526. Therefore, the area to the right of z = 1.62 is 1 - 0.0526 = 0.9474.
Finally, we can add the area to the left of z = -2.15 and the area to the right of z = 1.62 to find the total area under the normal distribution curve:
S = area to the left of z = -2.15 + area to the right of z = 1.62
S = 0.0158 + 0.9474
S = 0.9632
Therefore, the total area under the normal distribution curve is 0.9632.

Triangle X Y Z is shown. Angle Z W X is a right angle. An altitude is drawn from point W to point Y on side Z X to form a right angle. The length of W Y is 4, the length of Y X is a, the length of Z Y is 3, the length of Z W is c, and the length of W X is b.
What is the value of a?

5 and one-third units
6 and two-thirds units
7 units
Option B. 5 and one-third units. The value of a in triangle XYZ is 5 and two-thirds units. This is found using the Pythagorean theorem twice and solving for a.
To find the value of a, we can use the Pythagorean theorem in triangles WZY and WYX as follows:
In triangle WZY:
[tex]c^2 = 3^2 + (a + 4)^2[/tex]
In triangle WYX:
[tex]b^2 = 4^2 + a^2[/tex]
Since angle ZWX is a right angle, we can use the Pythagorean theorem in triangle ZWX as follows:
[tex]ZWX^2 = ZW^2 + WX^2[/tex]
We know that ZW = c and WX = b, so we have:
[tex]a^2 + b^2 = c^2[/tex]
Substituting[tex]c^2[/tex] in terms of a and simplifying, we get:
[tex]a^2 + b^2 = 25 + (a + 4)^2[/tex]
Expanding and simplifying, we get:
[tex]a^2 + b^2 = a^2 + 8a + 41[/tex]
Subtracting [tex]a^2[/tex] from both sides, we get:
[tex]b^2 = 8a + 41[/tex]
Substituting [tex]b^2[/tex] in terms of a in the equation [tex]a^2 + b^2 = c^2[/tex], we get:
[tex]a^2 + 8a + 41 = c^2[/tex]
Substituting[tex]c^2[/tex] in terms of a from the equation for triangle WZY, we get:
[tex]a^2 + 8a + 41 = 9 + (a + 4)^2/16[/tex]
Expanding and simplifying, we get:
[tex]16a^2 + 128a + 656 = 9a^2 + 50a + 97[/tex]
Simplifying further, we get:
[tex]7a^2 + 78a - 559 = 0[/tex]
Using the quadratic formula, we get:
[tex]a = (-78 ± sqrt(78^2 + 4(7)(559))) / 14[/tex]
a = (-78 ± sqrt(49379)) / 14
Since a represents a length in a triangle, it must be positive. Therefore, we have:
a = (sqrt(49379) - 78) / 14 ≈ 6.67

What exactly is a histogram?
A histogram is a graphical depiction of numerical data distribution. It entails splitting the data range into intervals or bins and counting how many data points fall into each bin. Bins are often stated as non-overlapping, sequential intervals of a variable. The count or frequency of data points in the respective bin is represented by the height of each bar on the graph. Histograms are often used in statistics to illustrate data distribution and to find trends, outliers, and other data properties.
Now,
Given that
Total shows shown were=3+0+7+10+7+3=30

=> Person 1: 2 hours times $8 per hour = $16
=> Person 2: $4 hours x $8 per hour = $32 per person
=>Person 3: 3 hours x $8 per hour = $24 per person.
=> Person 4: 5 hours x $8 per hour = $40.
=> Person 5: One hour times $8 per hour equals $8.
Each person needs to bring at least $70 in order to join the festival. As a result, the disparity shown below can be used to describe this circumstance:
=> 16 + 32 + 24 + 40 + 8 ≥ 70
Simplifying the inequality's left side, we obtain:
=> 120 ≥ 70
We can infer that all of the friends were able to afford the festival because 120 is larger than 70.
