Answer:
One sample test of proportions
Step-by-step explanation:
Which test is most appropriate to test whether the proportion of skiers is not 0.50?
Since the test says to test whether the proportion of skiers is not 0.50, then here we will be studying just only the promotion of skiers without the comparison with snowboarders.
We have been given an hypothesized promotion and the test says to test against this proportion, so the appropriate test to use here is the one sample test of proportions
Easier if you first factor out the " - " sign. Then you have:
–8x3 – 2x2 – 12x – 3 = -1(<span>8x3 + 2x2 + 12x +3).
</span>
Start with 12 + 3. This factors to 3(4x+1). Next, focus on 8x^3+2x^2. This factors to 2x^2*(4x+1). So, the binomial factor 4x+1 is common to the first two terms and the second two terms. We get: (4x+1) ( 2x^2 + 3).
Now put the "-" sign back in, and we get - (4x+1) ( 2x^2 + 3) (answer)
Please note: Use "^" to denote exponentiation. 2x2 is meaningless; it should be 2x^2.
Answer:
Option The graph will be a dashed line with a y-intercept of negative eight and a slope of three. The graph will be shaded above
the line
Step-by-step explanation:
we have

The solution of the inequality is the shaded area above the dashed line The equation of the dashed line is 
The slope of the dashed line is positive 
The y-intercept of the dashed line is -8
see the attached figure to better understand the problem
50x + 2.50 = 120.
x = how many tables she cleans to get $120.
