Answer:
A prediction based on the data is reliable, because the means of the samples are close together.
Step-by-step explanation:
Test approved
The most accurate statement is A. A prediction based on the data is reliable, because the means of the samples are close together.
What is Mean?Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.
Given three data sets.
All the samples have 10 data points.
Number of data points = 10
Mean of sample 1 = 9.1
Mean of sample 2 = 9.4
Mean of sample 3 = 8.9
We can see that the mean of the three samples is so close to each other.
So the data is reliable.
Hence the option is A.

Hey there!
x + 8 = 19
SUBTRACT 8 to BOTH SIDES
x + 8 - 8 = 19 - 8
CANCEL out: 8 - 8 because it give you 0
KEEP: 19 - 8 because it give you the x-value

X^2+9x+7=y standard to vertex form
Answer:
y = (x + 4.5)² - 13.25
Step-by-step explanation:
y = x² + 9x + 7
We need to get a perfectly squared binomial as part of the right side.
Take the '9x' term, divide it in half, square it, add and also subtract it on the right side, as shown below. That would be (4.5)² = 20.25 added and subtracted.
y = x² + 9x + 7
y = x² + 9x + 20.25 + 7 - 20.25
y = (x² + 9x + 20.25) - 13.25
y = (x + 4.5)² - 13.25
y = (x + 4.5)² - 13.25
Vertex Form is y = a(x-h)² + k, where the parabola vertex is (h, k)
So if you wrote this as y = 1(x - [-4.5] )² + (-13.25), we would see that a = 1, and h = -4.5 and k = -13.25.
Vertex = (-4.5, -13.25)
I verified on a graphing calculator that this is indeed the vertex of the parabola.

Choose the polynomial that is written in standard form 7x^5+8x^8+27x
Don’t need the answer just couldn’t find the question lol so the answer is 3
Answer: Option d: -3*x^4*y + 2*x^2*y^2 + 5*y^3
Step-by-step explanation:
In standard form, the first term of the polynomial must be the term with the highest degree and on each subsequent term the degree decreases. In the case of two variables, the degree is equal to the sum of the exponents.
Then the correct option is d.
Where the degree of the first term is (4 + 1) = 5
The degree of the second term is (2 + 2) = 4
The degree of the third therm is 3.
We can see that the degree decreases as the term number increases, then the polynomial written in standard form is:
-3*x^4*y + 2*x^2*y^2 + 5*y^3

a. What is the area of the room in square feet?
b. How much would it cost to carpet the floor?
Answer:
a). 240sqft b). $2004 (+ labor I guess)
Step-by-step explanation:
the room is rectangular, so it's area is the product of the dimensions
12feet * 20feet = 240sqft
The cost is $8.35 per sqft, so we get
240sqft * $8.35/sqft = $2004
Answer:
A: 240
B: 1,980
Step-by-step explanation:
Finding the area of a 2d rectangle WxL, So it's 12x20 is 240.
I did 8.35 times the square footage, 240, and gotten 1,980.

What is the linear relationship?A linear relationship is a connection that takes the shape of a straight line on a graph between two distinct variables - x and y. When displaying a linear connection using an equation, the value of y is derived from the value of x, indicating their relationship.
The rule is given in the question, as follows:
y is 3 less than x
For each value of x in the first column, the corresponding value of y in the second column can be calculated by subtracting 3 from x.
For example, if x is 10, then y is 3 less than x, which is 7 (10 - 3 = 7).
Similarly, if x is 8, then y is 5 (8 - 3 = 5), and if x is 6, then y is 3 (6 - 3 = 3).

X Y
