A jar contains 8 red marbles, 10 blue marbles, and 2 yellow marbles. One marble is chosen at random. The color is recorded in the table and then it is returned to the jar. This is repeated 40 times. Based on this data, what color marble is likely to be chosen next? Why?
Answers
Answer:
blue
Step-by-step explanation:
blue has the most marbles in the jar so it is most likely to be picked

A city has 20 radio stations including 5 college stations. What is the probablility that a randomly chosen radio station in this city is a college radio station
Answers
Answer:
1/4
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
the probability that a randomly chosen radio station in this city is a college radio station = number of college stations / total number of city radio stations

Answers
Step-by-step explanation:
-19x - 11 = -144
collect like terms,
-19x = -144 + 11
-19x = -133
Divide both sides by the coefficient of x
-19x/-19 = -133/-19
-19 cross with -19 leaving x, negative cross with negative leaving 133/19
133÷19
Therefore, x = 7

Based on the data provided by Connor, the correlation coefficient of the relationship is -0.84.
What is the correlation coefficient?
Correlation is used to determine the type of relationship that exists between two variables.
A negative correlation is when the two variables move in opposite directions. If one variable increases, the other variable decreases. A negative correlation has a negative sign in front of it.
The correlation coeffcieenct can be determined using a financial calculator.

Hi there! This is very similar to a question that I had yesterday, so I will do my best to try to answer it! I’m only in middle school, so this may not be correct :)
Step-by-step explanation:
First set up a diagram. The length of the string is the hypotenuse, and the angle of elevation is as pictured below. Use SOH CAH TOA to find the correct ratio, and then solve for “x”. Once you solve for “x” (height) add the 5 inches to the total, and your answer will be there! :)
The axis of symmetry for a function in the form f(x) = x2 + 4x − 5 is x = −2. What are the coordinates of the vertex of the graph?

(−2, −9)
Answers
Answer:
D) [tex](-2,-9)[/tex]
Step-by-step explanation:
Vertex Form of a Vertical Parabola:
[tex]y=a(x-h)^2+k[/tex]
Vertex -> [tex](h,k)[/tex]
Axis of Symmetry -> [tex]x=h[/tex]
Vertical Scale Factor -> [tex]a[/tex]
To turn [tex]f(x)=x^2+4x-5[/tex] into vertex form, we need to complete the square on the right sideTherefore, if [tex]f(x)=0[/tex], then [tex]0+9=x^2+4x-5+9[/tex] completes the square on the right side This becomes [tex]9=(x+2)^2[/tex]This means that our function in vertex form is [tex]f(x)=(x+2)^2-9[/tex]Therefore, the vertex of the graph is [tex](h,k)=(-2,-9)[/tex].
The coordinates of the vertex of the graph is (-2, -9).
What are Quadratic Functions?Quadratic functions are polynomial functions consisting of variables and exponents and the degree of the variable is 2.
The general form of a quadratic function is f(x) = ax² + b x + c.
Given is a quadratic function,
x² + 4x - 5
Given that axis of symmetry of the function is x = -2.
So the x coordinate of the vertex = -2.
y coordinates = f(-2) = 4 - 8 - 5 = -9
Hence the vertex is (-2, -9).

How do you find the equations of the vertical and horizontal asymptotes for a graph when you only have the graph and no function?
Answers
Answer:
See below for answer and explanations (as well as an attached graph)
Step-by-step explanation:
Pay attention to the behavior of the asymptotes. If the asymptotes are approaching a certain x-value or y-value, then that value is undefined for the function.
Take for example [tex]y=\frac{1}{x}[/tex]:
As x approaches ∞ and -∞, then y approaches 0, which is our horizontal asymptoteAs y approaches ∞ and -∞, then x approaches 0, which is our vertical asymptoteSee the graph for a visual.
