Answer:
f(3) = 11
Step-by-step explanation:
f (x)=3x+ 2
Let x= 3
f (3) =3*3+ 2
= 9+2
= 11
Answer: 0
Step-by-step explanation:
Let statements :
Let x be the number of tickets sold for an adult
Let y be the number of tickets sold for a child
Equations :
x + y = 280 OR y = 280 - x
4x + 2y = 1320
Substitution (sub the 2 equations in together) :
4x + 2(280 - x) = 1320
4x + 560 - 2x = 1320
2x = 1320 - 560
x = 760/2
x = 380
x is the number of tickets sold for the adults. meaning that 380 adults went.
Find the # of children :
x + y = 380
we know that x = 380
380 + y = 380
y = 380 - 380
y = 0
Conclusion :
No children went because the movie was rated R. Only adults attended.
Answer:
y = x₂ - 1.5 × x₁.
Step-by-step explanation:
Regression model is a technique of analysis in which a variable known as dependent variables and another variables known as the independent variables are analyzed to determine their relationship.
So, from the question given above we have that; "Suppose that participants who adhere to a particular weight loss program lose an average of 1.5 lbs per week".
Also, we are given that time = x1 (in weeks) and weight = x2 (in pounds). Therefore the regression equation is given as below;
y = x₂ - 1.5 × x₁.
Answer:
Step-by-step explanation:
y = -(x-5)²-10
