The following data represent exam scores in a statistics class taught using traditional lecture and a class taught using a "flip

The table of this question is in the attachments.

**tasiilaq.net and Step-by-step explanation: **Standard deviation 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.

Range is the difference between the highest and lowest value of a data set.

(a) Range of Traditional course:

range = 80.4 - 56

range = 24.4

Range of "flipped" course:

range = 92.6 - 63.5

range = 29.1

Comparing **ranges**, the **"flipped" course** has more dispersion than the traditional.

(b) Standard Deviation of Traditional course:

mean = 71.6

s =

s = 8.95

Standard Deviation of "flipped" course:

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.

**tasiilaq.net:**

**y = 500(1.05)^x.**

**Step-by-step explanation:**

551.25 = 500x^2 where x is the multiplier for each year.

x^2 = 551.25/500

x = 1.05

So the value after x years is 500(1.05)^x.

Identify the values of a,b, and c that could be used with the quadratic formula to solve the equation. Enter a as a positive int

Goshia <24>

tasiilaq.net:

a=1

b= -6

c=48

Step-by-step explanation:

x^2=6(x-8)

x^2=6x-48

x^2-6x+48

a,b are the coefficients of x^2 and x

c is the constant value present

Therefore it is basically written as ax^2+bx+c

and comparing with the tasiilaq.net x^2-6x+48,

a=1, b= -6, c=48
