Answer: 225 a^2 b^2
first you’d work within the parentheses and multiply 5 by 3, after that you square everything (multiply everything by itself)
Using margin of error, it is found that increasing the sample size results in a smaller sampling error.
The equation for the <em>margin of error</em> is given by:

In which:
- c is the critical value according to the distribution used.
- s is the standard deviation, either of the sample or of the population.
From the equation, it can be noted that the margin of error is inversely proportional to the square root of the sample size, hence, increasing the sample size results in a smaller sampling error.

Answer:
Slope= -7
Step-by-step explanation:
I like to use the rise/run method.
Take the point at (1,-2) and count up to (1, 7). Then because it is going left, you count your run over 3 points. Or you could do.

Answer:
Step-by-step explanation:
Hey there!
In order to solve this equation, you need to first simplify and take the absolute value:
x+2+x+2-x+5
Now you need to simplify
x+9
So, the rewritten form of the equation is x+9
The correct answer is B) $3,250, because if you add up the numbers consecutively you get that.
