Option: A is the correct answer.
The quadratic regression equation for the data set is:
A. y = 0.056x²+1.278x-0.886
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
here, we have,
We are given a set of data value as:
x y
3 3.45
5 6.9
6 8.79
8 12.91
10 17.48
12 22.49
15 30.85
On plotting these points on a scatter plot we see that the line that best fits these data points is a parabola i.e. the equation is a equation of a quadratic function.
The equation of the line of best fit is:
y = 0.056x²+1.278x-0.886

Answer:
x = 11.74739484
Step-by-step explanation:
To solve this problem, you can use trig functions. We are given an angle and the side next to it, and we are looking for the side opposite it. The perfect trig function to use for this would be tangent:
tan(θ) = opposite / adjacent
We can substitute the values we already have:
tan(40) = x / 14
x = 14 * tan(40)
We can evaluate this using a calculator and get:
x = 11.74739484

Answer:Step-by-step explanation:
Which is true about the line whose equation is x = 5?
The slope is undefined.
The y-intercept is 4.
The value of x always equals the value of y.
The slope is zero.
Answer:
the slope is undefined
Step-by-step explanation:
Since x=5, the graph is a straight vertical line when x=5. Since the line is vertical and not horizontal, the slope is undefined. If the line was horizontal then the slope would equal zero.

Two of the statements are true; one is a lie.
Select the one that is a lie.
Then explain your reasoning.
∠BAF and ∠CAF are complementary.
∠BAF and ∠BAC are adjacent.
∠DAC and ∠CAB are supplementary.
Answer:
Angle BAF and angle BAC is incorrect.
They overlap: adjacent angles do not overlap.
Answer: Choice B
angle BAF and angle BAC are adjacent
=============================================================
Explanation:
Let's go through each of the answer choices.
Choice A is true since angles BAF and CAF form a right angle (90 degree angle). So we can rule this out.Choice B is false. This is the answer. Adjacent angles must share a common ray or side, which does happen with the two angles in question (both share ray AB); however, note that angle BAF is completely inside angle BAC. We cannot have this overlap, or any overlap at all, when it comes to adjacent angles. Choice C is true. The two angles combine or glue together to form a straight angle, which is 180 degrees. We can rule this answer choice out.heeeeeeeeeeeelppppppppppppppppppppppppppppp
1. The Agent Earned $6,303
First, the real estate agency will earned 5.5%
5.5/100 * $382,000 = $21,010
Then, the agent earns 30% of $21,010
30/100 * $21,010 = $6,303
2. Basically, we're setting up an equation where Option A and Option B are the same amount.
For option A, you are making 23 dollars each hours, for 40 hours. (40*23)
For option B, you are making 4% of your sales. We're looking for how much she sells, so we can write that as x. (.04x)
Set the 2 options as equal and solve for x. so x is 920(.04x
sorry if wrong it was really hard
3. If 90% are women, 10% are men.

Use the distributive property to write an equivalent expression.
3(4x - 8y + 5)
Answer:
12x - 24y + 15
Step-by-step explanation:
The distributive property multiplies all of the terms by 3.
So:
3(4x) + 3(-8y) + 3(5) =
12x + (-24y) + 15 =
12x - 24y + 15

Answer:
legs
Step-by-step explanation:
Answer:
The Legs of a right triangle are the two sides of a right triangle that intersect to form the right angle
Step-by-step explanation:
Right Angle Triangle-Two legs plus a hypotenuse make up a right triangle. The hypotenuse is the longest side of the right triangle and the side opposite the right angle, and the two legs meet at a 90° angle. Right triangles come in a variety of shapes, including 45°-45° right triangles and 30°-60° right triangles.

Johnny was buying pizza rolls. One sausage pizza roll cost 1.54 and he also bought pepperoni flavored rolls. If he buys 6 sausage rolls and 10 pepperoni rolls and he spends $22.54 in total. How much does a pepperoni roll cost?
Answer:
$1.33
Step-by-step explanation:
multiply 6 by 1.54 to see how much he spent on sausage rolls
subtract that from the total ($22.54)
divide by 10 to see how much each pepperoni roll costs
Answer:
$1.33
Step-by-step explanation:
1.54x6=9.24
22.54-9.24=13.30
