-5p > -30
Divide both sides by -5 so that the only thing remaing on the left side is the variable p.
Final Answer: p>6
Answer:
The 99% confidence interval for the mean distance from home to work for all residents of this state is between 8.49 and 9.19 miles.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Z-table as such z has a p-value of .
That is z with a pvalue of , so Z = 2.575.
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 8.84 - 0.35 = 8.49 miles.
The upper end of the interval is the sample mean added to M. So it is 8.84 + 0.35 = 9.19 miles.
The 99% confidence interval for the mean distance from home to work for all residents of this state is between 8.49 and 9.19 miles.

Answer:
A
Step-by-step explanation:
Let's first define what exactly the values of a, b, and c represent.
- a: this is the coefficient of the x^2 term
- b: this is the coefficient of the x term
- c: this is the constant term (no variable attached)
Our equation is: y = 7x^2 - 3x + 9.
The coefficient of x^2 is 7, so a = 7. The coefficient of x is -3, so b = -3. And finally, the constant term is 9, so c = 9.
Thus, the answer is A.
