F(x)=x^2-3x+1/2, if f(4)
Substitute x with 4, to get
f(x)=x^2-3x+1/2
f(4)=4^2-3(4)+1/2
f(4)=16-12+1/2
f(4)=4+1/2
f(4)=4 1/2 or 4.5. Hope it help!
Answer:
0.65 is the correct answer
1.The sample is biased because it does not represent the population.
2.The question is biased toward a Yes response.
Answer:
1/2
Step-by-step explanation:
There are a total of 25 students. 3 don't study art or biology. 10 study only biology. 6 study both art and biology. This means the remaining students only study art.
1. Calculate the number of students taking art
only art: 25 - 3 - 6 - 10 = 6
number of students taking art and biology: 6
total number of students taking art: 12
2. Calculate the probability
Out of the 12 total students taking art, 6 are in art and biology.
6/12 = 1/2
Answer:
x= -1
Step-by-step explanation:
4x+3=x
we subtract x to both sides of the equation:
4x -x +3 = x-x
we have:
3x +3 = 0
we subtract 3 to both sides of the equation:
3x +3 -3 = -3
3x = -3
we divide by 3 both sides of the equation
3x/3 = -3/3
x= -1
we test the result in the original equation:
4x+3=x
4*(-1) + 3 = -1
-4 +3 = -1
-1 = -1
so finally x= -1
