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:
13.5
Step-by-step explanation:
13.50 is already rounded to the nearest tenth because the 5 is in the tenth place.
13.50 is basically 13.5
If you're looking for 13.5 rounded to the nearest ones or whole number, the answer would be 14 because any number that is five or greater is rounded up while any number that is four or less is rounded down.
Answer:
Marcy paid $4.15
Step-by-step explanation:
Given
Represent hotdogs with x and chips with y.
So, we have:
<u>Jamal</u>
<u>Kenny</u>
<em>See attachment for complete question</em>
Required
Determine the amount for 2x and 3y
From Jamal's and Kenny's orders we have:
--- (1)
--- (2)
Multiply (1) by 3
![3 * [3x + 2y = 4.85]](https://tex.z-dn.net/?f=3%20%2A%20%5B3x%20%2B%202y%20%3D%204.85%5D)
--- (3)
Subtract (2) and (3)
Solve for x
Substitute in
Solve for y
So, the cost of 2x and 3y is:

As the graph shows the cost of apples at a local market, Use the graph to answer problems 1-3</h2>
Part 1)
What is the cost of 1 apple and of 3 apples? How do you know?
Answer:
From the given graph which shows the cost of apples at a local market, it is clear that:
When we buy 1 apple, the cost is indicating 0.5+ (0.5/2) = 0.5+0.25 = $0.75
We know because x-axis is representing the number of apples and y-axis is representing the cost.
Therefore, when the number of apples is 1 on x-axis, then the cost is showing $0.75 on y-axis.
also
when we buy 3 apple, the cost is indicating 2+ (0.5/2) = 2+0.25 = $2.25
We know because x-axis is representing the number of apples and y-axis is representing the cost.
Therefore, when the number of apples is 3 on x-axis, then the cost is showing $2.25 on y-axis.
Part 2)
What does the point (0, 0) represent in this context?
- The (0, 0) represents the origin of the graph.
It means that the cost will be zero US dollars if you do not buy any apple. In other words, for 0 number of apples, the cost will be $0.
Part 3)
What does the point (2, 1.5) represent in this context?
The (2, 1.5) represents that when you buy 2 apples, the cost for buying 2 apples will be $1.5.
We know because x-axis is representing the number of apples and y-axis is representing the cost.
Therefore, when the number of apples is 2 on x-axis, then the cost is showing $1.5 on y-axis.
The absolute value is 16/5
