Answer:
Ok, we know that the driving accuracy is of 71%.
Then the first step is to get a spinner that is enumerated from 1 to 100 (in such way that each number is equispaced)
Now, we can mark a section between numbers 1 and 71. (this regio represents the cases where the shot lands in the fairway) and the unmarked region represents the cases where the shot does not land in the fairway.
Now, for each shot, we can spin our spinner next to a fixed pencil, depending on the section of the spinner that is marked by the pencil when the spinner fully stops, we can guess if the shot landed or not in the fairway.
In this way the shot has the region from 1 to 71 (71%) to land in the fairway
and the region from 72 to 100 to not land in the fairway.
If you want to simulate Sorenstam’s performance in a round of golf where she attempts 15 drives, you need to spin the spinner 15 times, and record the oucomes.

what is 1680 mm in feet
5.51181102 feet (5 feet 6 9⁄64 inches)
this question is difficult. can someone explain plz! asap
Answer:
See below.
Step-by-step explanation:
Central angles AOB and DOC are vertical angles, so they are congruent.
m<AOB = 50°
BD is a diameter, so the measure of central angle BOD is 180°.
The measure of an arc of a circle is equal to the measure of the central angle that subtends it.
m<AOB + m<AOE + m<EOD = 180°
50° + m<AOE + 60° = 180°
m<AOE + 110° = 180°
m<AOE = 70°
m(arc)AE = m<AOE = 70°
m(arc)AB = m<AOM = 50°
A full circle has 360 deg of central angle and of arc measure.
m(arc)ECB = 360° - m(arc)AE - m(arc)AB
m(arc)ECB = 360° - 70° - 50°
m(arc)ECB = 240°
Angle BOC is vertical with angle AOD.
m<BOC = m<AOD = m<AOE + m<EOD
m<BOC = 70° + 60°
m<BOC = 130°

ITS REALLY IMPORTANT
can somebody please explain how to find the surface and lateral area please and thank you!!
Answer:
The lateral area of the figure = 480 m²
The surface area = 720 m²
Step-by-step explanation:
By definition, we have;
The lateral area is the area of the vertically facing sides of or the area of the triangular faces of a pyramid
The surface area is the area of the entire surface = Lateral area + The other surface areas of the object
For a pyramid, the surface area = Lateral area + Area of base
The figure in the question is a pentagon based pyramid with five triangles on the sides
The lateral area of the figure = 5 × area of the 5 triangles = 5 × Base × Height
The lateral area of the figure = 5 × 12 × 8 = 480 m²
The lateral area of the figure = 480 m²
The surface area = Area of the base + Lateral surface area
Area of the regular pentagon base = 1/2 × Perimeter of the pentagon × Apothem
Perimeter of the pentagon = 5 × 12 = 60 m
Apothem = Perpendicular distance from the pentagon's side to the center = 8.3 m
∴ Area of the regular pentagon base = 1/2 × 60 × 8 = 240 m²
∴ The surface area = 240 +480 =720 m²
The surface area = 720 m²
A man traveled 1/3 of the distance between
two cities in 3/4 of an hour. At this rate, how
many hours will it take him to travel the
entire distance between the two cities?
Answer: 2 hours 15 minutes
Step-by-step explanation:
3/4 of an hour times 3 will be 9/4; each fourth is 15 minutes. 9 times 15 is 135 minutes, which is 2 hours and 15 minutes
Answer:
2.25 hours
Step-by-step explanation:
The man traveled 1/3 of the distance in 3/4 of an hour.
This means that he needs to travel for 3 times as long to travel the entire distance.
3 * 3/4 = 9/4 = 2.25
2.25 hours.
Or, 2 hours and 15 minutes (as 0.25 = 1/4).
What is the maximum number of pages the report can have so that it can be completely stored on a USB drive that holds 4 \cdot 10^6 \text{ KB}4⋅10 6 KB4, dot, 10, start superscript, 6, end superscript, start text, space, K, B, end text?
Answer:
2,300,000pages report.
Step-by-step explanation:
Given a USB drive with memory of 4.6*10⁶KB, in order to know the maximum number of pages a report can have so that it can be completely stored on the drive, the conversion factor must be used.
We must first understand that 1 page of a document uses up approximately 2kB of the storage.
Since 2kB = 1page
4.6*10⁶KB = x page
Cross multiply
2kB * x = 4.6*10⁶KB * 1
2x = 4.6*10⁶
x = 4.6*10⁶/2
x = 2.3*10⁶
x = 2,300,000
Hence the maximum number of pages that the report can have so that it can be completely stored on a USB drive that holds 4.6*10⁶KB is approximately 2,300,000pages report.

[tex]\boxed{ \sf Option \ 4}[/tex]
Step-by-step explanation:
The domain is all possible values for x.
There are no restrictions on x. The domain is all real numbers.
The range are all possible values of F(x) or y.
[tex]F(x)=5^{3(3)}= 1953125[/tex]
[tex]F(x)=5^{3(0)}= 1[/tex]
[tex]F(x)=5^{3(-2)}= 0.000064[/tex]
When the value of x increases, the value of F(x) increases until infinity. When the value of x decreases, the value of F(x) gets closer to 0 but does not equal to 0.
The range is [tex]y>0[/tex]
The coefficient of 3 does not affect the domain and range, as there are no real restrictions.

Yes , the series is an arithmetic sequence of common difference 2
What is Arithmetic Progression?
An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"
The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁
Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]
Given data ,
Let the number of terms n = 20
The number of tiles in the first row = 10 tiles
The number of tiles in the second row = 2 more than first row
The number of tiles in the second row = 12 tiles
The number of tiles in the third row = 14 tiles
So , the sequence will be , 10 , 12 , 14 , 16 ...
The number of terms n = 20
The first term a = 10
The common difference d = second term - first term
The common difference d = 12 - 10 = 2
The series is an arithmetic sequence and the 20th term of the sequence will be
a₂₀ = a + ( n - 1 )d
a₂₀ = 10 + ( 19 ) 2
a₂₀ = 10 + 38
a₂₀ = 48 tiles
Hence , the series is an arithmetic sequence

Answer:
The population of Namibia in the years 1940, 1997, and 2005 was 371.2 , 1671.64 and 2064.74 respectively.
Step-by-step explanation:
Refer the attached figure
We will use equation calculator to find the equation of given plot

We are supposed to find the population of Namibia in the years 1940, 1997, and 2005.
x values are years
y values are population
For 1940, [tex]x = -10, y = y = 483.36 \times e^{0.0264(-10)} = 371.2[/tex]
For 1997, [tex]x = 47, y = y = 483.36 \times e^{0.0264 \times 47} = 1671.64[/tex]
For 2005,[tex]x = 55, y = y = 483.36 \times e^{0.0264 \times 55} = 2064.74[/tex]

Step-by-step explanation:
(-2)(1/4)=-1/2

the third term of the geometric sequence with first term = 1/4 and common ratio r = -2 is 1
We have a geometric sequence in which the first term is [tex]\frac{1}{4}[/tex] and the common ratio is -2.
We have to find the third term of this geometric sequence.
What is the formula to find the [tex]n^{th}[/tex] term of a geometric sequence?The formula to find the [tex]n^{th}[/tex] term of a geometric sequence with first term [tex]a_{1}[/tex] and common ratio r is -
[tex]a_{n} =a_{1} r^{n-1}[/tex]
In our question, [tex]a_{1}[/tex] = [tex]\frac{1}{4}[/tex] and r = -2 and n =3.
Substituting the values, we get -
[tex]a_{3} =\frac{1}{4}(-2)^{3-1} = \frac{1}{4} (-2)^{2} =\frac{1}{4}\times4=1[/tex]
Hence, the third term of the geometric sequence with first term = 1/4 and common ratio r = -2 is 1.
