Center : Mean Before the introduction of the new course, center = average(121,134,106,93,149,130,119,128) = 122.5 After the introduction of the new course, center = average(121,134,106,93,149,130,119,128,45) = 113.9 The center has moved to the left (if plotted in a graph) because of the low intake for the new course. Spread before introduction of the new course : Arrange the numbers in ascending order: (93, 106,119, 121), (128, 130,134, 149) Q1=median(93,106,119,121) = 112.5 Q3=median(128,130,134,149) = 132 Spread = Interquartile range = Q3-Q1 = 19.5 After addition of the new course,
(45,93, 106,119,) 121, (128, 130,134, 149)
Q1=median(45,93,106,119)=99.5
Q3=median (128, 130,134, 149)= 132
Spread = Interquartile range = 132-99.5 =32.5
We see that the spread has increased after the addition of the new course.
Answer:
<h2>24j - 16 = 8(3j - 2)</h2>
Step-by-step explanation:
The distributive property: <em>a(b - c) = ab - ac</em>
24j - 16 = (8)(3j) - (8)(2) = 8(3j - 2)
1/2 = 50%
3/4 = 75%
So something in between that could be 2/3 (which equals 66.67% )
A few others could be: 3/5 ( equals to 60% ) , 7/10 ( equals 70%)
Hope that helps :)
