Answer:
2/45
Step-by-step explanation:
First chooses a polka dot shirt: 2 / (5+6+2+2) = 2/15
Then a striped shirt, after replace: 5/15 = 1/3
the probability that she chooses a polka dot shirt then a striped shirt:
2/15 x 1/3 = 2/45
Answer:
the anwer is D: 44,44,92
Step-by-step explanation:
2n+10=4n+2 ---->8=2n ------> n=4
11n=11(4)=44
m<N=m<L=44
180-44-44=92
The vertex will be when the velocity is equal to zero:
df/dx=-12x+24 (using the power rule for differentiation)
df/dx=0 only when:
-12x+24=0 add 12x to both sides
12x=24 divide both sides by 12
x=2, we find the y value to be:
y(2)=-6(2^2)+24*2-20
y(2)=-24+48-20=4
So the vertex is the point (2,4)
And the axis of symmetry is the line x=2
Now if you do not yet do calculus...
The vertex will occur midway between the two zeros.
6x^2-24x+20=0 (using the Quadratic Formula for simplicity)
x=(24±√96)/12
x≈(1.1835, 2.8165)
Now the vertex occurs at the average of the zeros...
x=(1.1835+2.8165)/2=2 (as we saw earlier)
y(2)=4
Vertex is at (2,4) and axis of symmetry is the vertical line x=2
Solution of the equation:
Step-by-step explanation:
The equation that we have to solve in this problem is:
The first step to do is to rewrite the mixed fractions as improper fractions. We have:
And
So the equation becomes
Now we multiply by 4 each term on both sides, and we get
Now we subtract 29 from both sides,
And finally, we divide both sides by 4:
