Answer is YES.
Steps for Comparing a Data Set by Measures of Center & Variation:
Measure of center: a value that describes the center of a set of data. Measures of center include the mean, median, and mode.
Measure of variability: a value that describes how spread out numbers in a data set is. Measures of variability include the range and mean absolute deviation.
Step 1: Calculate the measure of center/variation for each set of data.
Step 2: Compare the two measures of center/variation based on the problem.

Question 5)

Question 6)
-$2250.80 (Are you sure you wrote this out correctly? She has minus 450, then withdraws 1,250.80, then pays 550? So she starts off in debt, and continues to go in debt? They're all subtractions.
Step-by-step explanation:
Q1)
46.5 - 32.5 = 14
Q2)
There are 66 months in 5 and half years. So:
66 * 50 = 3,300.
Q3)
The rock travels 778 feet, from Omar to the bottom. Omar is sitting 22.2 feet from the surface of the pond. So the distance from the surface to the bottom of the pond is:
778 - 22.2 = 755.8 feet
Q4)
There are 42 months in 3 and half years. So
42 * 75 = $3,150
Q5)
The rock travels 556 feet, from Daniella to the bottom. Daniella is sitting 90.3 feet from the surface of the pond. So the distance from the surface to the bottom of the pond is:
465.7 feet
Q6).
She starts out with (-$450). She withdraws (I'm assuming she has a decent overdraft or something) another $1,250.80. Then buys (with money she doesn't have, further going into her overdraft) a pair of vapormax for $550. So you're just start at (-$450) and subtracting the other two values.
(-$450) - $1,250.80 - $550 = -$2250.80

What is the equation in point-slope form of the line that passes through the points (7, 5) and (-4, -1)
Answers
Answer:
y - 5 = (-6/11)(x - 7)
Step-by-step explanation:
Looking at the points (7, 5) and (-4, -1), we see that x decreases by 11 (from 7 to -4) and y decreases by 6 (from 5 to -1). Therefore, the slope of this line is m = rise / run = -6 / 11.
Start with the point-slope form y - k = m(x - h). Substitute the x- and y-coordinates of one of the given points for h and k in the above form:
y - k = (-6/11)(x - h) => y - 5 = (-6/11)(x - 7)
This is the equation of the line in question, in point-slope form.
Abigail's math teacher finds that there's roughly a linear relationship between the
amount of time students spend on their homework and their weekly quiz scores. This
relationship can be represented by the equation y = 6.2 + 69, where y represents
the expected quiz score and I represents hours spent on homework that week. What
is the meaning of the s-value when y = 91?
Answers
The time taken by the student to complete the weekly quiz if she had 91 is 3.55 hours
Given the linear relationship between the amount of time students spends on their homework and their weekly quiz scores expressed as:
y = 6.2s + 69
If the value of y is 91, we need to get the value of "s"
Substitute s = 91 into the function to have:
91 = 6.2s + 69
6.2s = 91 - 69
6.2s = 22
s = 22/6.2
s = 3.55
Hence the value of s when y is 91 is 3.55

for an infinite queuing situation, if the arrival rate for loading trucks is 5 trucks per hour, what is the mean time between arrivals?
Answers
Using proportions, it is found that the mean time between arrivals is of 12 minutes.
This question is solved by proportions, using a rule of three.In one hour(60 minutes), 5 trucks arrive, thus what is the time necessary for 1 truck to arrive?The rule of three is:
5 trucks - 60 minutes
1 truck - x minutes
Applying cross multiplication:
[tex]5x = 60[/tex]
[tex]x = \frac{60}{5}[/tex]
[tex]x = 12[/tex]
The mean time between arrivals is of 12 minutes.
