The final scores from the last five games of two basketball teams are given. Jumping Jackrabbits: 70, 65, 72, 80, 73 Leaping Lizards: 61, 47, 70, 63, 54
(a) Determine the MAD of each data set. In your work, show the mean and the absolute deviation of each data value in each set.
(b) Compare and interpret the MADs in context of the situation.
Using the Mean Absolute Deviation(MAD) concept, it is found that:
a) The Jumping Jackrabbits have a MAD of 3.6 and the Leaping Lizards of 6.8.
b) The MAD is lower for the Jumping Jackrabbits then for the Leaping Lizards, hence their scores are more consistent.
What is the mean absolute deviation of a data-set?The mean of a data-set is given by the sum of all observations divided by the number of observations.The mean absolute deviation(MAD) of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.The mean absolute deviation represents the average by which the values differ from the mean.Item a:
For the Jumping Jackrabbits, the mean and MAD are given by:
M = (70 + 65 + 72 + 80 + 73)/5 = 72
MAD = (|70 - 72| + |65 - 72| + |72 - 72| + |80 - 72| + |73 - 72|)/5 = 3.6.
For the Leaping Lizards, the mean and the MAD are given by:
M = (61 + 47 + 70 + 63 + 54)/5 = 59
MAD = (|61 - 59| + |47 - 59| + |70 - 59| + |63 - 59| + |54 - 59|)/5 = 6.8.
The Jumping Jackrabbits have a MAD of 3.6 and the Leaping Lizards of 6.8.
Item b:
The MAD is lower for the Jumping Jackrabbits then for the Leaping Lizards, hence their scores are more consistent.

Write and solve an addition or subtraction equation to find the missing angle measure
Answer:
90°
Step-by-step explanation:
The three angles : 45°, n°, and 45° will form a line.
A property of a line is that it creates a 180° angle.
⇒ 45 + n + 45 = 180⇒ n + 90 = 180⇒ n = 90°To rent a certain meeting room, a college charges a reservation fee of $49 and an additional fee of $5.40 per hour. The chemistry club wants to spend less than $86.80 on renting the meeting room.
Answer:
The maximum amount of money the chemistry club can spend without going over their buget is $81.4 ... With a total of 6 hours their allowed to use the room for.
Step-by-step explanation:
$49 is our constant and will not change. 5.40 however will. Let's use variable h for the amount hours they can rent the room for. Now we can make an inequality;
49+ 5.40h < 86.80
5.40h < 86.80
5.4h< 37.8
h< 7
Now that we know h will have to be less than seven for the chemistry club to spend less than their buget we can find that 6 is the maxium amount of hours they can spend in the room while staying within their budget.

A city’s bus line is used more as the urban population density increases. The more people in an area, the more likely bus lines will be utilized. The population of Belmont, MA, is 24,729 and covers an area of 4.66 mi2. The population of Easton, MA, is 23,112 and covers an area of 28.4 mi2. Which city’s residents are more likely to use public buses? Explain.
The residents of Belmont are more likely to use public transportation because the city has the highest population density.
The residents of Easton are more likely to use public transportation because the city has the highest population density.
The residents of both cities will not use the bus line because the population density is too high.
The residents of both cities are equally likely to use public transportation because the population densities are equal.
Answer with explanation:
it is given that city's bus line is used more as the urban population density increases.
Population density is defined as ,total population per unit Area.
→Population Density of Belmont

The owners of the resort want to expand and build a row of condos at the western base of the mountain. Because of the amount of snow, the area gets most winters, it is important to have the pitch (steepness) of the roof of each condo at least 60°. To make the condos appealing to skiers and boarders, they want to model the condos after their cabins, but on a larger scale. The cabins have an A-line roof that forms an isosceles triangle as shown, with the base angles at 65° . The base length is 6m. Note: the slant height is the length of the side of the roof. (Picture Below)
Required Formula
[tex]\sf cos(x) = \dfrac{adjacent}{hypotenuse}[/tex]
Part A
Given: base length: 6m, half base: 3m, angle: 65°, let hypotenuse: h
Hence solve,
[tex]\rightarrow \sf cos(x) = \dfrac{a}{h}[/tex]
[tex]\rightarrow \sf cos(65) = \dfrac{3}{h}[/tex]
[tex]\rightarrow \sf h = \dfrac{3}{cos(65)}[/tex]
[tex]\rightarrow \sf h =7.0986\ \approx \ 7.1 \ m[/tex]
The slant height is 7.1 meters when base length is 6 meter.
Part B
Given: base length: 9.6m, half base: 4.8m, angle: 65°, let hypotenuse: n
Hence solve,
[tex]\rightarrow \sf cos (x) = \dfrac{a}{n}[/tex]
[tex]\rightarrow \sf cos (65) = \dfrac{4.8}{n}[/tex]
[tex]\rightarrow \sf n = \dfrac{4.8}{cos (65)}[/tex]
[tex]\rightarrow \sf n = 11.357 \ \approx \ 11.4 \ m[/tex]
The slant height is 11.4 meters when base length is 9.6 meter.
Answer:
A) 7.1 m
B) 11.4 m

Trigonometric ratios
[tex]\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}[/tex]
where:
[tex]\theta[/tex] is the angleO is the side opposite the angleA is the side adjacent the angleH is the hypotenuse (the side opposite the right angle)Part AThe slant height of the roof is the hypotenuse of a right triangle.
Considering the information given, use the cos trig ratio to determine the slant height.
A roof's base length is the distance from one corner of the roof to the other. Therefore, the base length of the given right triangle is half the roof base length.
Given:
[tex]\theta[/tex] = 65°A = Half of roof base length = 6 ÷ 2 = 3 mH = Slant heightSubstituting the given values into the formula and solving for H:
[tex]\sf \implies\cos(\theta)=\dfrac{A}{H}[/tex]
[tex]\sf \implies\cos(65^{\circ})=\dfrac{3}{H}[/tex]
[tex]\sf \implies H =\dfrac{3}{\cos(65^{\circ})}[/tex]
[tex]\implies \sf H=7.1 \: m \: (nearest\:tenth)[/tex]
Part BThe slant height of the roof is the hypotenuse of a right triangle.
Considering the information given, use the cos trig ratio to determine the slant height.
A roof's base length is the distance from one corner of the roof to the other. Therefore, the base length of the given right triangle is half the roof base length.
Given:
[tex]\theta[/tex] = 65°A = Half of roof base length = 9.6 ÷ 2 = 4.8 mH = Slant heightSubstituting the given values into the formula and solving for H:
[tex]\sf \implies\cos(\theta)=\dfrac{A}{H}[/tex]
[tex]\sf \implies\cos(65^{\circ})=\dfrac{4.8}{H}[/tex]
[tex]\sf \implies H =\dfrac{4.8}{\cos(65^{\circ})}[/tex]
[tex]\implies \sf H=11.4 \: m \: (nearest\:tenth)[/tex]

The area of a circle is 9π in². What is the circumference, in inches? Express your answer in terms of \piπ
Answer:
[tex]6\pi[/tex] in
Step-by-step explanation:
The formula to find the area of a circle: [tex]\pi r^{2}[/tex], where [tex]r[/tex] is the radius.
The formula to find the circumference (perimeter) of a circle: [tex]2\pi r[/tex], where [tex]r[/tex] is the radius.
1) To find the circumference of the circle, we need to find the radius ([tex]r[/tex]) first. Since the area of the circle is given to us, we need to equate this to the formula to find the area of a circle.
[tex]9\pi =\pi r^2[/tex]
Cancel the [tex]\pi[/tex] by bringing it to the other side.
[tex]9 =\pi r^2[/tex] ÷ [tex]\pi[/tex]
[tex]9 = r^2\\\sqrt{9} = r\\3 = r[/tex]
2) Find the circumference of the circle by using the formula, [tex]2\pi r[/tex].
= [tex]2*\pi *3[/tex]
