The table of this question is in the attachments.
Answer and Step-by-step explanation: <u>Standard</u> <u>deviation</u> is a measure of how spread the data is from the mean. It is calculated as:
s = √∑(x - μ)² / n - 1
where μ is the mean of the set.
<u>Range</u> is the difference between the highest and lowest value of a data set.
(a) <u>Range of Traditional course</u>:
range = 80.4 - 56
range = 24.4
<u>Range of "flipped" course</u>:
range = 92.6 - 63.5
range = 29.1
Comparing ranges, the "flipped" course has more dispersion than the traditional.
(b) <u>Standard Deviation of Traditional course</u>:
mean = 71.6
s = 
s = 8.95
<u>Standard Deviation of "flipped" course</u>:
mean = 77.6
s = 
s = 8.3
Comparing standard deviation, traditional course has more dispersion.
(c) If you change one score, range for traditional will be:
range = 591 - 56
range = 535
Changing one score increase in almost 22 times the range for this category.
Answer:
The meaning of each statement is shown below.
Step-by-step explanation:
Assume that the given statements are
(a) c(0)=0
(b) c(3)=c(8)
(c) c(n)=29
(d) c(13)<c(12)
Let c(t) be the number of customers in a restaurant t hours after 8 A.M.
We need to find the meaning of each given statement.
(a) c(0)=0 means the number of customers 0 hours after 8 A.M (i.e., 8 A.M.) is 0.
(b) c(3)=c(8) means the number of customers 3 hours after 8 A.M (i.e., 11 A.M.) is equal to the number of customers 8 hours after 8 A.M (i.e., 4 P.M.).
(c) c(n)=29 means the number of customers n hours after 8 A.M is 29.
(d) c(13)<c(12) means the number of customers 13 hours after 8 A.M (i.e., 9 P.M.) is less than the number of customers 12 hours after 8 A.M (i.e., 8 P.M.).

Step-by-step explanation:
To determine which ordered pairs are solutions to the equation
Substitute the x and y values into the left side of the equation and if equal to the right side then they are a solution.
(- 1, - 6)
3(- 1) - 4(- 6) = - 3 + 24 = 21 = right side ← thus a solution
(- 3, 3)
3(- 3) - 4(3) = - 9 - 12 = - 21 ≠ 21 ← not a solution
(11, 3)
3(11) - 4(3) = 33 - 12 = 21 = right side ← thus a solution
(7, 0)
3(7) - 4(0) = 21 - 0 = 21 = right side ← thus a solution
The ordered pairs (- 1, - 6), (11, 3), (7, 0) are solutions to the equation
Answer:
Step-by-step explanation:
Given that a store receives shipments of peaches. They want to sort them by weight.
The sorting pattern is as follows:
Peaches : Pound = 2:1 or 3.25:1 or 1:3.25
Given are i) 26 peaches to 13 lbs = 26:13=2:1 Hence goes to the first box
ii) 6 peaches to 19.5 lbs =6:19,5 = 1:3,25 lb. Hence goes to II box
iii) 13 peaches to 4 lbs: =13:4=3.25:1 Hence goes to II box
iv) 39 peaches to 12 lbs: =39:12=3.25:1 Hence goes to II box
v) 15 peaches to 7.5 lbs: =15:7.5=2:1 Hence goes to I box
i - I box
ii - II box
iii - II box
iv) - II box
v) - I box
This is a combinations problem.
The total number of possible 2-item combinations is (1000 choose 2)
The number of 2-defective combinations is (300 choose 2)
The probability =
