the slope of line p is ___ and the slope of line q is ___

line p
a. -3
b. 1.5
c. 3

line q
a. -3
b. 1.5
c. 3
​

Answer:

Slope of line p = 3

Slope of line q = -3

Step-by-step explanation:

An easy way to find slope is to pick one point and move up the line to find the next point with exact coordinates.

For line p, we can use point (1,-1). Moving farther up the line, the next point that lands exactly on a coordinate, is (2,2) The slope of a line is the rise of a line over its run. Or, [tex]\frac{rise}{run}[/tex]. From the first point, we move up exactly 3 units, and over 1 unit to reach the next point. We rise 3 units and run 1 unit. In fraction form, [tex]\frac{3}{1}[/tex]. This simplifies to 3. The slope of line p is 3.

----------------------------------------------------------------------------------------------------------------

For line q, we can use the same method. Notice first that the line slopes down, which means the slope will be negative.

Now, we can pick a point on the line. Let's use the same one we used for line p, point (1,-1). The next point up the line is point (0,2). From point (1,-1), we rise 3 units, and run -1 unit. The run, we can tell, is negative, because it goes to the left. The slope is [tex]\frac{3}{-1}[/tex]. Simplify this to -3. The slope of line q is -3.

With individual lines at its various windows, a post office finds that the standard deviation for normally distributed waiting times for customers on Friday afternoon is 7.2 minutes. To test this claim, the post office experiments with a single, main waiting line and finds that for a random sample of 25 customers, the waiting times for customers have a standard deviation of 3.5 minutes. a) With a significance level of 5 percent, conduct an appropriate test on the claim. (State your null hypothesis, test statistic, critical value, decision rule, conclusion) (15 points) b) What is the 95% confidence interval for the population variance

Morgan needs to earn $16.31 more to have $40.00. Four students wrote and solved equations to find m, the amount of money that Morgan has now. Which student wrote and solved the equation correctly?
Sid’s work:
m minus 16 dollars and 31 cents = 40 dollars. M = 56 dollars and 31 cents.
Sora’s work:
m + 16 dollars and 31 cents = 40 dollars. M = 23 dollars and 69 cents.
Matt’s work:
16 dollars and 31 cents + 40 dollars = m. m = 56 dollars and 31 cents.
Zyad’s work:
16 dollars and 31 cents m = 40 dollars. M = 23 dollars and 69 cents.
