X3−18x2+107x−210
So this is a cubic function that needs to be factored:
what goes into 210? 7×30
and what goes into 30? 5×6
So double check the b & c values, but it should factor into (x-5)(x-6)(x-7)
So the roots/solutions (or x-intercepts) are where those 3 = 0, so x = 5, 6, and 7
For y-intercept set x = 0:
{x}^{3}  - 18 {x}^{2}  + 107x - 210\\ \: 0  - 0 + 0 - 210 =  - 210 \\ y =  - 210
graph starts low in 3rd quadrant, then crosses at y=-210 into 4th quadrant rising up to cross x-axis at 5, quickly back down at six, then up into 1st quadrant at 7

which of the following would be neither perpendicular nor parallel to the following equation. y=3x-7. equations: y=-1/3x-7, y=-1
UkoKoshka [18]

Answer:

y=1/3x+6

Step-by-step explanation:

Equations parallel to each other have the same slope so that rules out the fourth answer. Perpendicular equations have opposite and reciprocal slopes, which in this case would be \frac{-1}{3}, which rules out all of the others except for the third option.

In a random sample of 192 college students, 129 had part-time jobs. find the margin of error for the 95% confidence interval use
Setler [38]
<span>Given data show that 129 college students out of 192 have part time jobs. proportion p = 129/192 = 0.672 The estimated population proportion is p* = 0.672 Standard error = squareroot of [p*(1 - p*)/n] = 0.034 Value for 95% confidence interval = 1.96 margin of error = 1.96 x 0.034 = 0.067</span>
