Step-by-step explanation:
quizlet
at a 95% confidence interval By use of the table we have a critical value of 1.96, and so the margin of error is 1.96/(2 √ 900 = 0.03267, or about 3.3%.

Answer: a. (-2, -2)
Step-by-step explanation:
The point at which the two lines intersects is at (-2, -2), which is the solution.
Hello there!
To find the slope of a line, we need to know at least two points contained in the graph of the line.
The slope of a line passing through the points and is given by the formula: .
As we can see on the graph, two points contained on the line are and .
Using the formula above, we get that:
Subtract the values on both numerator and denominator of the fraction
This is the slope of this line we were looking for and is the answer contained on the 4th option.
Answer:
By checking it with multiplication
Step-by-step explanation:
You can use multiplication to check your division answer this way.
Do the division problem.
Multiply the quotient times the divisor.
If there is a remainder, add it to the multiplication product.
Compare this answer to the dividend. They should be the same number (630 = 630).
