The experimental probabilities of each outcome are given as follows:
Outcome of 1: 9/30 = 3/10.Outcome of 2: 5/30 = 1/6.Outcome of 3: 5/30 = 1/6.Outcome of 4: 7/30.Outcome of 5: 4/30 = 2/15.The theoretical probability of each outcome is given as follows:
1/5.
How to calculate a probability?A probability is calculated as the division of the desired number of outcomes by the total number of outcomes.
For the experimental probability, we consider the 30 trials in the table.
For the theoretical probability, we consider that each of the outcomes is equally as likely, hence the probability is given as follows:
p = 1/5.

Simplify the expression using positive exponents.
5^9 ⋅ 5^3
Answer:
244140625 or 5^12
Step-by-step explanation:
When it comes to multiplication, you add exponents IF the base (the 5 at the bottom is called base) is the same answer. for example: 1^16 x 1^9, since the exponents are the same you just add the exponents (16 & 9) which is 25 or 1^25
Dividing is the same as multiplying except your subtracting with the examples, adding and subtracting is simplifying and solving, for example
14^2 + 13^3
14 * 14 = 196
13*13*13 =2,197
196+2,197 = 2,393
Same thing for subtraction
13^3 - 14^2
2,197 - 196 = 2,001

Answer:

Step-by-step explanation:
I am not sure what your teacher wants but I guess you can say the following:
at n = 1, the cost is 4 dollars.
at n = 2, the cost is 8 dollars.
This trend is the same where the cost increases by 4 as n increases by 1. This means the C = 4n. We can check this by plugging values into the equation.
For the first row, C = 4, n = 1, and so the equation satisfies it. For the second row in the table, C = 8, n = 2, and so the equation works again. The other data points also agree using the equation.

How to find the system of equations needed to solve an equation?
An equation usually consists of equality of two mathematical expressions. Let it be
�
=
�
A=B . If we take them to be equal to third variable, then:

A=B=C type of equation is obtained.
We can then take it as system of two equations as:
�
=

�
=
�
A=C
B=C
Solution to this system will give us the solution to the considered equation
What is a solution to a system of equations?
For a solution to be solution to a system, it must satisfy all the equations of that system, and as all points satisfying an equation are in their graphs.
For the given case, we are given that:

Plotting these two functions on the X-Y plane, the common point of these curves is the common value which can satisfy both the equations simultaneously, and thus, being the solution to the considered system of equations.
Thus, the solutions are those two points that are intersections of those two curves.
Which of the following allows you to compare the frequency of intervals, but not the frequency of exact values?
A.a dot plot
B.a stem-and-leaf plot
C.a histogram
D.a circle graph
The type of graph that allows you to compare the frequency of intervals, but not the frequency of exact values is a stem-and-leaf plot.
What is a Histogram?An histogram is a graphical representation of a data distribution, which uses bars or bins to represent the frequency of the data distribution that are in intervals.
Similarly, in dot plot the total number of dots tells us the total number of observations of the values of that thing we did.
The Stem and leaf plot is to show the data distribution while retaining its uniqueness which shows the raw values by retaining the original data,
The type of graph that allows you to compare the frequency of intervals, but not the frequency of exact values is a stem-and-leaf plot.
Therefore, the graph used to show data in intervals is: B.a stem-and-leaf plot

Find the perimeter of the figure. Round your answer to the nearest hundredth.
Answer:
40.56 in.
Step-by-step explanation:
8 × 3.14 × 1/2 = 12.56 (perimeter for the half circle)
12.56 + 10 + 8 + 10 = 40.56
Answer:
Perimeter = 40.56 inches
Explanation:
The perimeter of a shape is all side lengths added up, so, we know there are sides with the lengths 10 inches, 10 inches, 8 inches, and a semicircle.
To find the perimeter of a semicircle, the formula is
C = πd/2, circumference equals pi times diameter divided by 2 OR C = πr, circumference equals pi times radius.
The diameter is 8, so, filling out the formula, it's
C = 3.14 x 8 /2
C = 25.13/2
C = 12.56
So, adding all the sides up, it's 10 in. + 10 in. + 8 in. + 12.56 in.
Therefore, the answer/perimeter/circumference is 40.56 inches.

While walking to the gym, Marie decides to play a game using a her lucky fair

indicate walking forward that many steps and, likewise, tossing an odd number would

Function 1: None of the Above
Function 2: Quadratic
Function 3: Linear
Step-by-step explanation:
Function 1: It isn't linear because the y-axis doesn't go up or down at a constant rate, it isn't quadratic because it doesn't have a vertex, and it isn't exponential because it doesn't continue going up.
Function 2: It has a vertex-(6,32)
Function 3: The y-axis goes up at a constant rate of 6.

The kite shown below is translated 8 units to the right and 1 unit up.
Which property will remain the same?
A.
the coordinates of the x-intercept
B.
the coordinates of the vertices
C.
the perimeter of the kite
D.
the angle between the top vertex and the origin
Answer:
C. The perimeter of the kiteStep-by-step explanation:
Answer A is not correct because if the kite moves both right and up, the x and y coordinates will change
Answer B is the same as answer A. The kite moved so the coordinates will change.
Answer D is also the same. If the kite moves both on the x and y axis, any angle and distance will change.
Answer C is correct. Since C does not rely on the coordinates, it will always be the same. The position of a shape does not change it´s perimeter.

A rectangle has sides that are 10 m, 10m, 5m, and 5 m. What is the rectangle’s length?
5m
20 m
10 m
30 m
The way the question is worded is a little confusing.
I think I would say 10m. It could be 5m, but usually they list length first, then width. The perimeter, the whole distance around the outside, is 30 m (10 + 10 + 5 +5)
The length of the rectangle will be 10 m.
What is a rectangle?A rectangle is a two-dimensional shape (2D shape) in which the opposite sides are parallel and equal to each other and all four angles are right angles.
Given that, a rectangle has sides that are 10 m, 10 m, 5 m, and 5 m.
We need to find the length of the rectangle,
We have the dimensions 5 m x 10 m,
Lengths in a rectangle tells that how much the rectangle is long and the width tells how much the width tells about the breadth of the rectangle,
So, we can say that,
Length = 10 m
Width = 5 m
Hence, the length of the rectangle is 10 m.

Answer:
Yes this is a function.
Step-by-step explanation:
This graph is a function because it passes the vertical line test. The vertical line test ensures that no x value has more than one y value. You can take a pencil, hold it vertically, and move it horizontally across your paper to test whether or not the graph contains multiple y values for a single x value. If it passes this test, then the graph is indeed a function.

sandra calculated the trend line for a scatter plot to b y=3x+1-. What is the predicted value of x=40?
a. 80
b. 125
c. 130
d. 53
The predicted value of the scatter plot at x=40, according to Sandra's trend line prediction will be 130.
What is a scatter plot?A scatter plot is a form of plot or mathematical diagram that displays values for two variables for a collection of data using Cartesian coordinates. One more variable can be presented if the points are programmed.
To get the predicted value to the scatter plot at x=40, substitute the value of x as 40 in the given function of the trend line. Therefore, the value will be,
[tex]y = 3x+10\\\\y = 3(40)+10\\\\y=130[/tex]
Hence, the predicted value of the scatter plot at x=40, according to Sandra's trend line prediction will be 130.
