6 0, 6
e.
Answer:
Step-by-step explanation:
a, First arrange the data in ascending order:
77 79 80 81 84 84 86 88 92 95 <-- ten numbers.
Mean = sum of the numbers / 10
= 846/10
= 84.6.
The median is the middle number in the ordered list, or if there are an even number of values, the mean of the 2 middle numbers. There are 10 numbers here, so the median = (84+84)/2 = 84
Median = 84.
The mode is the value that occurs most. Here we have 2 84's so
Mode = 84.
Parts b to d are done in the same way as for the above, note if there is no mode write None.
For the stem leaf data first write out individual vales and then proceed as in a).
Values = 31 32 40 41 43 44 45 46 47 51 54 52 60 66

The economy of Rayton can be described by the following statistics:
Current real GDP = $10,000
Full employment real GDP = $12,000
Tax revenue = $3000
Government transfer payments = $1000
Government spending = $3000
a) In what stage of the business cycle is the Rayton economy? Explain.
b) What is the current budget balance in Rayton? Show your work.
c) Senator Fullington, an influential politician in Rayton, has argued that the budget must be
balanced. How could this be accomplished? How would balancing the budget affect real GDP in
Rayton?
Based on the current real and the full employment real GDP, Rayton's economy is at a Recession stage.
The current budget balance in Rayton is -$1,000. The budget can be balanced by reducing government spending or increasing taxes. Both of these would decrease real GDP.
What does the economic data on GDP show?The fact that the current real GDP is less than the full employment GDP shows that the nation is at a recession stage where it is underperforming.
What is the current budget balance?This can be found as:
= Government revenue(taxes) - government spending
= 3,000 - 1,000 - 3,000
= -$4,000
In order to make a balanced budget where government revenue will equal government spending, the government either needs to reduce spending or increase revenue ( taxes ).
Increasing taxes or reducing spending, will lead to less money available for spending in the economy which will lead to a decrease in real GDP.

Find the area of the shaded region. Express your answer in terms of \piπ and do not round any numbers.
Answer:
The strategy is to find out the total area and find the area of the 3 circles then subtract the sum of the circles' are from the total area
Total area = (length * width) = ( 3+6+9+12) * 18 = 540 sq. inch
3 Circles area = πr₁² + πr₂² + πr₃²
r₁= 12/2 = 6 in r₂ = 9/2 = 4.5 in r₃ = 6/2 = 3 inπr₁² + πr₂² + πr₃²
π(6²) + π(4.5)² + π(3)²
= 36π + 20.25π + 9π
= 65.25π
Shaded area = 540 - 64.25π = 335.011 sq. in

Find the equation of the tangent line to the curve y=
The equation of the tangent line to the given curve (which is parallel to line (2x−y+9=0) is y−2x−3=0.
What is the equation of tangent?There are two important elements to finding an equation that defines a tangent line: its slope and its point of contact with a curve.
The equation of the given curve is;
[tex]\rm y=x^2-2x+7[/tex]
On differentiating with respect to x, we get:
dx/dy=2x−2
The equation of the line is;
2x−y+9=0
y=2x+9
The slope of the line =2
If a tangent is parallel to line 2x−y+9=0, then the slope of the tangent is equal to the slope of the line.
Therefore, we have:
2=2x−2
2x=4
x=2
Now, at x=2
y=22−2×2+7=7
Thus, the equation of the tangent passing through (2,7) is given by,
y−7=2(x−2)
y−2x−3=0
Hence, the equation of the tangent line to the given curve (which is parallel to line (2x−y+9=0) is y−2x−3=0.

topic: Inscribed Quadrilateral theorem in a Circle
Answer:
Step-by-step explanation:
Problem 12
Comment
A cyclic quadrilateral (a 4 angled quadrilateral where all 4 corners touch the circumference of a circle), has the property that opposite angles add up to 180 degrees.
Formula
4x + 9 + 3x + 3 = 180 Collect like terms
Solution
4x + 3x + 9 + 3 = 180 Combine
7x + 12 = 180 Subtract 12 from both sides
7x + 12 -12 = 180 - 12 Combine
7x = 168 Divide by 7
7x/7 = 168/7
x = 24
Answer
x = 24
Problem 13
Comment
Same comment as was given for problem 12
Formula
3x + 2 + 3x - 32 = 180 Collect like terms
Solution
3x + 3x +2 - 32 = 180 Combine
6x - 30 = 180 Add 30 to both sides
6x -30+30 = 180 + 30
6x = 210 Divide by 6
6x/6 = 210/6
x = 35

Find the new dimensions of the figure given at right when it is enlarged by scale factor of 2.5 then find the perimeter and area of the original and enlarge it figure
The perimeter and area of the original are 20 ft and 23.5 square ft and the enlarged figure are50 ft and 146.875 square ft.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The figure is the combination of a triangle and a square.
The area of the original (A₀) figure will be
[tex]\rm A_o = \dfrac{1}{2} \times 3 \times 5 + 4 \times 4\\\\A_o = 23.5 \ ft^2[/tex]
The perimeter of the original figure (P₀) will be
[tex]\rm P_o = 3 + 5 + 4 + 4 + 4\\\\P_o = 20 \ ft[/tex]
The scale factor is 2.5.
Then the dimension of the triangle will be
h = 2.5 × 3 = 7.5 ft
b = 2.5 × 5 = 12.5 ft
Then the dimension of the square will be
a = 2.5 × 4
a = 10 ft
The area of the new figure will be
[tex]\rm A = \dfrac{1}{2} \times 7.5\times 12.5 + 10*10\\\\ A = 146.875 \ ft^2[/tex]
The perimeter of the new figure will be
[tex]\rm P= 7.5 + 12.5 + 10+ 10+ 10\\\\P = 50 \ ft[/tex]

50 points please help
please explain your answer please ( such as formula n such )
Answer:
See below ~
Step-by-step explanation:
Part (a) :
Formula : Perimeter = 2 (Length + Width)⇒ 278 = 2(54 + Length)⇒ 139 = 54 + LengthLength = 139 - 54 = 85 mPart (b) :
Formula : Area = Length × Width⇒ 8811 = 99 x Width⇒ Width = 8811/99Width = 89 cmAnswer:
(a) The length is 85 m.
(b) The width is 89 cm.
Step-by-step explanation:
(a)
Perimeter (P) formula using the length (L) and width (W) of a rectangle.
P = 2L + 2W
P = 278 m
W = 54 m
278 = 2L + 2(54)
2L + 108 = 278
2L = 170
L = 85
Answer: The length is 85 m.
(b)
Area (A) formula using the length (L) and width (W) of a rectangle.
A = LW
A = 8811 cm²
L = 99 cm
8811 = 99 × W
W = 8811/99
W = 89
Answer: The width is 89 cm.
