Step-by-step explanation:
Let x = Number of pounds of Horse Food
Let y = Number of pounds of Medical Supplies
so
0.3x+0.4y=8000----1
x+y=20000-----------2
multiply eqn 2 by 0.3 to eliminate x we have
0.3x+0.4y=8000
0.3x+0.3y=6000
-0+0.1y=2000
0.1y=2000
y=2000/0.1
y= 20000
put y=2000 in eqn 2
x+20000=20000
x=20000-20000
x=0
its quite unfortunate that for her to maximize the opportunity and the money she has to carry 20,000 pounds of only Medical Supplies
Your answer should be 73. This is because all the interior angles of a triangle equate to 180
If I’m correct, could you please give me brainliest?
Answer:
1- Opposite
2- Adjacent
Step-by-step explanation:
Answer:
Step-by-step explanation:
equation of the circle (x - 4)² + (y - 1)² = 9
Length of the vertical leg comes from subtracting the y values of (4, 1) and (4, 3) 3 - 1 = 2
Horizontal leg = √(3² - 2²) = √5
Answer:
a. the line that makes the sum of the squares of the vertical distances of the data points from the line (the sum of squared residuals) as small as possible.
Step-by-step explanation:
If we have N points and we want to adjust a model
We can define the error associated to this like that:
So as we can see here we are adding the square distances between the real and the adjusted values in order to minimize the error for this reason the correct answer is:
a. the line that makes the sum of the squares of the vertical distances of the data points from the line (the sum of squared residuals) as small as possible.
For this case we need to calculate the slope with the following formula:
Where:
And we can find the intercept using this:
