Answer:
10%
Step-by-step explanation:
50+50=100
45+45=90
100-90=10
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:
the equation for y=20=1/2
Step-by-step explanation:
y=1/4
y=0.25
I think is d that what i tink
Let the largest number be x:
smallest number=1/2x
middle number=3/4x
total sum of the numbers is:
x+1/2x+3/4x=252
9/4x=252
solving for x we get
x=252×4/9
x=112
thus the largest number is 112
middle number=3/4*112=84
smallest number=1/2×112=56
Answer: 56,84,112
