Solution :
a). The required linear regression model is
Price = ![$-1242.986 + 75.017 \times \text{age of part} + 13.973 \times \text{ number of bidders}$](https://tex.z-dn.net/?f=%24-1242.986%20%2B%2075.017%20%5Ctimes%20%5Ctext%7Bage%20of%20part%7D%20%2B%2013.973%20%5Ctimes%20%5Ctext%7B%20number%20of%20bidders%7D%24)
b). The
for the variable "Age of part" is 0.0000
Since the
is less than 0.05, so it is significant to the model.
The p-value for the variable "Number of bidders" is 0.1940
Since
is not less than
, so it is significant to the model.
c). We cannot say that model is significant because variable " the number of bidders" is not significant.
But as both variables have positive coefficient so as the variable increases the price received for the item also increased.
Answer:
Step-by-step explanation:
I think you meant y = -x^n, where ^ denotes exponentiation.
If n is odd, the graph begins in Quadrant II and decreases through the origin into Quadrant IV. This is true of -x, -x^3, -x^5, and so on.
Answer:
<h3>The answer is 17.5 units</h3>
Step-by-step explanation:
Using the distance formula
<h3>
![d = \sqrt{ ({x2 - x1})^{2} + ({y2 - y1})^{2} }](https://tex.z-dn.net/?f=d%20%3D%20%20%5Csqrt%7B%20%28%7Bx2%20-%20x1%7D%29%5E%7B2%7D%20%2B%20%20%28%7By2%20-%20y1%7D%29%5E%7B2%7D%20%20%7D%20)
</h3>
the distance between (-10, 12) and (5, 3) is
<h3>
![d = \sqrt{ ({5 + 10})^{2} + ({3 - 12})^{2} }](https://tex.z-dn.net/?f=d%20%3D%20%20%5Csqrt%7B%20%28%7B5%20%2B%2010%7D%29%5E%7B2%7D%20%20%2B%20%20%28%7B3%20-%2012%7D%29%5E%7B2%7D%20%7D%20)
</h3><h3>
![d = \sqrt{ {15}^{2} + ( { - 9})^{2} }](https://tex.z-dn.net/?f=d%20%3D%20%20%5Csqrt%7B%20%7B15%7D%5E%7B2%7D%20%20%2B%20%28%20%7B%20-%209%7D%29%5E%7B2%7D%20%7D%20)
</h3><h3>
![d = \sqrt{225 + 81}](https://tex.z-dn.net/?f=d%20%3D%20%20%5Csqrt%7B225%20%2B%2081%7D%20)
</h3><h3>
![d = \sqrt{306}](https://tex.z-dn.net/?f=d%20%3D%20%20%5Csqrt%7B306%7D%20)
</h3><h3>
![d = 3 \sqrt{34}](https://tex.z-dn.net/?f=d%20%3D%203%20%5Csqrt%7B34%7D%20)
</h3>
d = 17.492855
We have the final answer as
<h3>d = 17.5 units to the nearest tenth</h3>

Answer:
Shaquille O'Neal's height= 2,160,000,000 nm
= 2.16 × 10^9 nm
Completed question;
The basketball player Shaquille O'Neal is 7 feet 1 inch tall, which is equivalent to 216 centimeters a nanometer (nm) is a unit of measurement that is one-billionth of a meter, convert his height to nanometers.
Step-by-step explanation:
Given;
Shaquille O'Neal's height= 216cm = 216 × 1/100 m = 2.16m
Since, a nanometer (nm) is a unit of measurement that is one-billionth of a meter.
1 m = 1 billion nanometers
So,
2.16m = 2.16 billion nm = 2160000000 nm
Shaquille O'Neal's height= 2160000000 nm
= 2.16 × 10^9 nm
C. $693.33. Just round. It helps. Round 2,080 to 2,100. Then whats 30% of 2,100? It's easy just think of 21 divided by 3, which equals 7. So, 700 and the closest answers to that is $693.33. That's just the easy way instead of doing the math out. And it is also common sense that B or D wouldn't be it. So your left with C or A. :)
