Answer:
The point (-4,5) is on the line
Step-by-step explanation:
You can replace the x and y values to determine if it is a true statement
First Statement
5= 2(-4)+13 -> 5= -8+13 -> 5=5 true
Second Statement
-4=2(5)+13 -> -4= 10+13 -> -4 ≠ 23 false
You can automatically eliminate the next two answers because you already found that the first statement is true and because you can find points using an equation.
There is not relationship between the size of a school building and the number of students who play an instrument because the scatterplot does not have a cluster.
Answer: Option A.
<u>Explanation:</u>
A scatterplot is a type of data display that shows the relationship between two variables. It makes use of the Cartesian coordinates to plot the values of the two variables for a set of data. This is used to show how much is one variable is affected by the other variable.
Since in the scatterplot which is being talked about in this question, it is scattered and is not clustered, this shows that there is no relationship between the size of the school and the number of the students who play instruments in the school.

Find Area of the circle:
------------------------------------------------------------------------------
Area of a circle = πr²
Area of the largest possible circle = π x(12 ÷ 2)²
Area of the largest possible circle = 113.10 ft²
------------------------------------------------------------------------------
Find Area of the square board:
------------------------------------------------------------------------------
Area of a square board = Length x Length
Area of the square board = 12 x 12
Area of the square board = 144 ft²
------------------------------------------------------------------------------
Find area of the remaining board:
------------------------------------------------------------------------------
Area of the remaining board = 144 - 113.10
Area of the remaining board = 30.90 ft²
------------------------------------------------------------------------------
Answer: The area of the remaining board is 30.90 ft².

Answer:
A) <RXZ and <YXZ
Step-by-step explanation:
I just took the test
Answer:
The answer to the given problem is provided below.
Step-by-step explanation:
She can make the conclusion at 95% confidence level that average sales have increased:
Since the sample mean, $2,984, falls outside the range of likely sample means (which has an upper bound=$2,843.44), the store owner can reject the null hypothesis that μ≤ $2,700 μ≤ $2,700 at a 95% confidence level.
Since she can reject the null hypothesis, she can essentially accept the alternative hypothesis and conclude the average daily sales have increased.
