1. Use a line plot to represent the data in the data set. Be sure to include a title and label all tick marks.
2. What is the largest amount of snow that fell in one day?
3. What is the least amount of snow that fell in one day?
4. How many days did it snow 3 inches?
5. A new piece of data was recorded and added to the line plot. The dierence between the largest and
smallest amounts of snow is now 3. What could the new values of the data be?
Since the data set and specific values are not provided in your question, I am unable to create a line plot for you.
How we can use the line plot?However, I can explain how to create a line plot based on the given data. To create a line plot, follow these steps:
a. Determine the range of values in the data set, i.e., the smallest and largest amounts of snowfall.
b. Draw a number line that spans the range of values.
c. Mark each amount of snowfall as a dot above the corresponding value on the number line.
d. Label each dot with the number of inches of snowfall.
e. Add a title to the line plot that describes the data being represented.
To find the largest amount of snow that fell in one day, look for the highest point on the line plot or identify the largest value from the data set.
To find the least amount of snow that fell in one day, look for the lowest point on the line plot or identify the smallest value from the data set.
To determine how many days it snowed 3 inches, count the number of dots on the line plot that correspond to 3 inches of snowfall.
If the difference between the largest and smallest amounts of snow is now 3, there are several possibilities for the new values. Here are a few examples:
a. The largest amount of snow could be 6 inches, and the smallest amount could be 3 inches.
b. The largest amount of snow could be 5 inches, and the smallest amount could be 2 inches.
c. The largest amount of snow could be 4 inches, and the smallest amount could be 1 inch.
These are just a few examples, and there can be other combinations of values that satisfy the given condition. Without further information, it's difficult to provide a more specific answer.

Suppose you roll a cube 30 times, what is a to describe the theoretical of rolling a 1, 4, 6, 7 Please help me!
Answer:
\(Pr(x) = \frac{1}{6}\)
Step-by-step explanation:
Given
\(n = 30\) --- number of rolls
Required
The theoretical probability of rolling: (a) 1 (b) 4 (c) 6 (d) 7
Assume the cube is 6 sided.
The sample space is:
\(S = \{1,2,3,4,5,6\}\)
And the probability of each is:

Suppose that six different experimental runs are to be made on the first day of experimentation. Of the six are randomly selected from among all the possibilities, so that any group of six has the same probability of selection, what is the probability that a different catalyst is used on each run
The probability of using a different catalyst for each run is 1.
The given data can be expressed as follows: Six different experimental runs are to be made on the first day of experimentation. If six are randomly selected from among all the possibilities, so that any group of six has the same probability of selection, what is the probability that a different catalyst is used on each run?
We are to determine the probability of using a different catalyst for each run, which is the probability of choosing the six catalysts from six different catalysts. Possible number of ways to select 6 catalysts from 6 = 6C6 = 1
Thus, there is only one way to select 6 different catalysts for 6 different runs. Therefore, the probability of using a different catalyst for each run is 1.

Find the solution to the system of equations.
The solution to the system of equations, x = 7y - 3 and x + 7y = 8, is: (5/2, 11/14).
How to Find the Solution tp a System of Equations?One way to solve a system of equations is to use substitution.
We can start by substituting the first equation into the second equation:
x + 7y = 8
(7y - 3) + 7y = 8
7y + 7y - 3 = 8
14y - 3 = 8
14y = 11
y = 11/14
Now that we know the value of y, we can substitute it back into the first equation to find x:
x = 7y - 3
x = 7(11/14) - 3
x = 11/2 - 3/2
x = 8/2 - 3/2
x = 5/2
So the solution to the system of equations is (x, y) = (5/2, 11/14)

Given information:
Start point is (6, 0).
End point is (7,8).
The curve is linear, hence we can find the slope of the line passing through (6, 0) and (7, 8).
Slope of the line:
\($$m = \frac{y_2 - y_1}{x_2 - x_1}$$$$m = \frac{8 - 0}{7 - 6}$$$$m = 8$$\)
Using point-slope form of equation of line, we get:
\($$y - y_1 = m(x - x_1)$$$$y - 0 = 8(x - 6)$$$$y = 8x - 48$$\)
Therefore, x-coordinate is given by:
\($$x(t) = t + 6$$\)
And, y-coordinate is given by:
\($$y(t) = 8t$$\)
Hence, parametric equations that define the curve starting at (6,0) and ending at (7.8) are
\($$(x(t),y(t)) = (t+6,8t)$$\)
where parameter t varies from 0 to 1.

The probability distribution for the number of defective items in a random sample is as follows: x: 0 1 2 3 4 p(x) : 1 0.15 13 07 0.55
calculate:
expected value of X = ____
From the probability distribution for the number of defective items in a random sample, the expected value of X is 2.82.
To calculate the expected value of X, we need to multiply each possible value of X by its corresponding probability and sum them up.
The expected value of X, denoted as E(X) or μ, is calculated using the formula:
E(X) = ∑ (x * p(x))
where x represents each possible value of X and p(x) represents the corresponding probability.
In this case, the probability distribution for X is given as follows:
x: 0 1 2 3 4
p(x): 0.1 0.15 0.13 0.07 0.55
To calculate the expected value, we perform the following calculations:
E(X) = (0 * 0.1) + (1 * 0.15) + (2 * 0.13) + (3 * 0.07) + (4 * 0.55)
E(X) = 0 + 0.15 + 0.26 + 0.21 + 2.2
E(X) = 2.82
The expected value represents the average value or mean of the probability distribution. In this case, it represents the average number of defective items we expect to find in a random sample based on the given probabilities.

McKenzie has a 2 quart pitcher.she fills itup two times with juice.how many cups ofjuice was she able to make?
Since McKenzie fills the 2-quart pitcher 2 times, there are a total of 4 quarts.
2 quarts × 2 times filled = 4 quarts
Recall that
1 quart = 4 cups
Since each quart is 4 cups, having 4 quarts is equivalent to
4 quarts × 4 = 16 cups
Therefore, there are a total of 16 cups of juice that was made.
Determine the equation of the circle with radius \(111\) and center (9,5)
The equation of the circle with a radius of 111 and a center at (9, 5) is:
To determine the equation of a circle, we use the standard form equation:
\((x - h)^2 + (y - k)^2 = r^2\)
Where (h, k) represents the center coordinates of the circle, and r represents the radius.
In this case, the center of the circle is (9, 5), and the radius is 111. Plugging these values into the equation, we have:
(x - 9)^2 + (y - 5)^2 = 111^2
Expanding and simplifying further:
\((x - 9)^2 + (y - 5)^2 = 12321\)
Therefore, the equation of the circle with a radius of 111 and a center at (9, 5) is:
(x - 9)^2 + (y - 5)^2 = 12321
This equation represents all the points (x, y) that are equidistant from the center (9, 5) by a distance of 111 units, forming a circle shape.
To graphically represent the circle, plot the center point (9, 5) on a coordinate plane and then draw the circle with a radius of 111 units around it. Any point on the graph that satisfies the equation will lie on the circle, while points outside the circle will not satisfy the equation.
It's important to note that the equation of a circle can also be expressed in other forms, such as the general form or parametric form. However, the standard form equation provided above is commonly used for representing circles.

Angie has to fill in a reading log for her English class. She is required to read a total of 10 and 5 over six hours a week. On Monday she read 1 and 1 over 3 hours, Tuesday she read 3 over 4 of an hour and Thursday she read 3 hours. How many total hours does she still need to read in order to get full credit?
Given:
She is required to read a total = \(10\dfrac{5}{6}\) hours a week.
Monday she read \(1\dfrac{1}{3}\) hours.
Tuesday she read \(\dfrac{3}{4}\) of an hour.
Thursday she read 3 hours.
To find:
The total hours does she still need to read in order to get full credit.
Solution:
Total time = \(10\dfrac{5}{6}\) hours a week.
Total time she already read \(=1\dfrac{1}{3}+\dfrac{3}{4}+3\) hours
\(=\dfrac{1\times 3+1}{3}+\dfrac{3}{4}+3\) hours
\(=\dfrac{4}{3}+\dfrac{3}{4}+3\) hours
\(=\dfrac{16+9+36}{12}\) hours
\(=\dfrac{61}{12}\) hours
Now,
Remaining time = Total time - Total time she already read
\(=10\dfrac{5}{6}-\dfrac{61}{12}\)
\(=\dfrac{65}{6}-\dfrac{61}{12}\)
\(=\dfrac{130-61}{12}\)
\(=\dfrac{69}{12}\)
\(=\dfrac{23}{4}\)
\(=5\dfrac{3}{4}\)
Therefore, the required time is \(5\dfrac{3}{4}\) hours.
