Step-by-step explanation:
Mean=sum of data/no of data
=161/7
=23
median
first of all arrange the data frome ascending to descending order
4,14,18,23,28,35,39
median=(N+1)/2(N=no of data)
=7+1/2
=8/2

Find the area of the circle to the nearest whole number, if necessary.
Answer:
Area of a Circle = πr²
R=Diameter/2
=21mm
=π(21)²
=1385.44mm²
To the nearest whole number
= 1385mm²
The answer is in mm². It may differ if the given answer is in m². You can get this by converting your radius to meters. This is done by dividing 21mm by 1000.

Identify the lateral area and surface area of a regular triangular pyramid with base edge length 10 ft and slant
height 14 ft
Answer:
L = 315 cm2 ; S = 399.9 cm2
Step-by-step explanation:
Lateral area;
3 × (½)(14)(15)
315 cm²
Surface area:
315 + (½)(14)(14)sin(60)
399.8704896 cm²
Lateral surface area of the regula triangular pyramid is 210 ft²
Surface area of the regular triangular pyramid is 253.30 ft²
Lateral area and Surface area of a triangular pyramid: Expression for the lateral area of a regular triangular pyramid is given by,
Lateral surface area = 3(Area of one lateral triangular side)
Expression for the total surface area is given by,Surface area = Area of the triangular base + Lateral surface area
Given in the question,
Base with the edge length = 10 feet Slant height = 14 ftLateral surface area = [tex]3(\frac{1}{2})(\text{Base})(\text{Slant height})[/tex]
= [tex]\frac{3}{2}(10)(14)[/tex]
= 210 ft²
Area of the regular triangular base = [tex]\frac{\sqrt{3} }{4}(a)^2[/tex]
= [tex]\frac{\sqrt{3} }{4}(10)^2[/tex]
= 25√3 ft²
= 43.30 ft²
Therefore, total surface area = 210 + 43.30
= 253.30 ft²
Hence, lateral surface area of the regula triangular pyramid is 210 ft²
Surface area of the regular triangular pyramid is 253.30 ft²

Advertising A bank manager wants to encourage new customers to open accounts with principals of
at least $2,500. He decides to make a poster advertising a simple interest rate of 3%. What must the
principal be if the bank manager also wants to advertise that one can eam $10 the first month? Can
the poster correctly say, "Open an account of $2,500 and earn at least $10 interest in 1 month!"?
Explain your answer (be careful he said 1 MONTH).
Answer:
The poster say, "Open an account of $3,500 and earn at least $10 interest in 1 month!" is correct
Step-by-step explanation:
Given, A bank manager wants to encourage new customers to open accounts with principals of at least $3,500.
He decides to make a poster advertising a simple interest rate of 4.8%.
We have to find what must the principal be if the bank manager also wants to advertise that one can earn $10 the first month
We know that, banks offer simple interest
In our problem, simple interest = $10, rate = 4.8%, time = 1 month
Let us see Can the poster correctly say, "Open an account of $3,500 and earn at least $10 interest in 1 month!"?
So now, in our problem, amount = $3500, rate = 4.8% and time = 1 month =
So, the statement is correct.
Hence, amount to be invested is $2500 and poster says correctly.

Draw an angle of -45 degrees in standard position . Then find the reference angle
Answer:
45°
Step-by-step explanation:
-45° would be 360°-45°=315°
Since 315° is in Quadrant IV, then its reference angle is 360°-315°=45°
So really, -45° is just 45° clockwise which is also our reference angle.
Is this correct????????
Answer:
ummm yes

SOMEONE PLZ HELP ME T_T
Answer:
7x - 1
Step-by-step explanation:
Whole rectangle:
Length = x + 5
Width = x - 1
Area of the whole triangle = length × width
= (x + 5) (x - 1)
= x² - x + 5x - 5
= x² + 4x - 5
Unshaded rectangle:
Length = x + 1
Width = x - 4
Area of the unshaded rectangle = length × width
= (x + 1) (x - 4)
= x² - 4x + x - 4
= x² - 3x - 4
Area of the shaded region = Area of the whole rectangle - Area of the unshaded rectangle
= (x² + 4x - 5) - (x² - 3x - 4)
= x² + 4x - 5 - x² + 3x + 4
= 7x - 1
Area of the shaded region = 7x - 1
