Answer:
Independent variable or explanatory variables.
Step-by-step explanation:
this variable is referred to as the independent variable.
A linear regression equation is of the form
Y = B0 + B1X1 + u
Y is the depndent variable
X1 is the independent variable
With u as the error term.
The independent variable is used to explain changes in Y, which is the dependent variable. The independent or explanatory variable has a direct effect on the dependent variable. This means that as X1 changes, Y would also change in response to the changes in the independent variable.
Using function concepts, it is found that the correct option is given by:
a.Yes, this graph represents a polynomial. There are two turning points and the least degree possible is three.
<h3>What is the least degree possible of a polynomial?</h3>
Supposing a polynomial with n turning points, the least possible degree is of n + 1.
In this problem, the polynomial has 2 turning points, hence the least possible degree is of 3 and option a is correct.

Answer:
<em>He should use 800 pounds of trail mix 5% raisins and 200 pounds of trail mix 20% raisins</em>
Step-by-step explanation:
<u>System of Equations</u>
Let's call
x = pounds of trail mix 5% raisins
y = pounds of trail mix 20% raisins
The distributor wants to make 1,000 pounds of trail mix, thus:
x + y = 1,000 [1]
The mix must be 8% raisings as a combination of x and y, thus:
5x + 20y = 8*1,000 = 8,000
Dividing by 5:
x + 4y = 1,600 [2]
Subtracting [2] and [1]:
4y - y = 1,600 - 1,000
Operating:
3y = 600
y = 200
From [1]
x = 1,000 - y = 1,000 - 200
x = 800
He should use 800 pounds of trail mix 5% raisins and 200 pounds of trail mix 20% raisins
Answer: 40x+18
