Answer:
<em>Briana's thinking is incorrect because the numbers are different when you substitute x with numbers other than 0.</em>
the two equations that are equivalent to each other are,
<u><em>5x+x−4 and 9x-3x-4</em></u>
Step-by-step explanation:
Expression A: 9x−3x−4
Expression B: 12x−4
Expression C: 5x+x−4
First I will substitute x for each of the equations.
9x-3x-4
when x equals: , then y equals:
1 = 9(1)-3(1)-4= 2
2 = 9(2)-3(2)-4=8
3 = 9(3)-3(3)-4= 14
Now for 12x-4
when x equals: , then y equals:
1 = 12(1)-4= 8
2 = 12(2)-4= 20
3 = 12(3)-4= 32
And for the final equation:
5x+x−4
when x equals: , then y equals:
1 = 5(1)+(1)−4= 2
2 = 5(2)+(2)−4 = 8
3 = 5(3)+(3)−4=14
Based on this you can now see that the two equations that are equal are:
<u><em>5x+x−4 and 9x-3x-4</em></u>

Given:
Northern Florida: 2,000 patients ; 64% experienced flulike symptoms during December
Southern Florida: 3,000 patients ; 54% experienced flulike symptoms during December
Standard error = √[p(1-p)/n]
NF = √[0.64(1-0.64)/2000] = √[(0.64*0.36)/2000] = 0.0107 or 1.07%
SF = <span>√[0.54(1-0.54)/3000] = √[(0.54*0.46)/3000] = 0.0091 or 0.91%
smallest margin of error for a 95% confidence interval
NF: Em </span>≈ 0.98/√2,000 = 0.98/44.72 = 0.0219 or 2.19%
<span>SF: Em </span>≈ 0.98/√3,000 = 0.98/54.77 = 0.0178 or 1.78%

S-t-upid people everywhere
They make me want to pull your hair
Don’t get me wrong I think you’re cool
But all the others are just fools
We’re going places this ain’t fair
This cycle is getting me nowhere
At night I close my eyes and dream
Humans are more of an i-d-i-o-t than they seem
Emptiness surrounds this hole
Of what? Well I don’t really know
Answer:
The cubic volume of concrete needed to complete the ramp is 360 ft³
Step-by-step explanation:
We note that the ramp shape is that of a right ngled triangular cube with dimensions
Height = 10 ft
Base = 12 ft
Width = 6 ft
The amount of concrete to fill the ramp is approximately the volume of the ramp.
Volume of ramp = volume of triangular prism = 0.5×Base ×Height × Width
Volume of ramp = 0.5×12×10×6 = 360 ft³.
The cubic volume of concrete needed to complete the ramp = 360 ft³.
