Which of the following situations models a geometric sequence?
~The amount of cell phone users increases by 33% every year.
~Amount of cakes in a bake sale increases by 3 each year the fundraiser is held
~Uranium loses half of its weight every 415 years.
~A family of rabbits doubles in size every 3 months.
~A car drives at a constant speed of 58 mph.
~The number of students in a school increases by 122 each year.
~The number of pieces of chalk in a classroom decreases by 10 throughout the school year.
(If you can explain what geometric sequences are that'd be really helpful too)
Thanks~ :D
Answer:
1,3 and 4 because the amount of change between the amount of time differs
Step-by-step explanation:
Answer:
1.The amount of cell phone users increases by 33% every year.
2.Uranium loses half of its weight every 415 years.
3.A family of rabbits doubles in size every 3 months.
Step-by-step explanation:
We will check each and every option given here.
1) Amount of cell phone users increases by 33% every year.
Its a geometric sequence because the number of users are increasing exponentially every year.
2) Amount of cakes in bake sale increases by 3 each year the fundraiser is held.
amount of cakes is increasing with a common difference of 3 so it's an arithmetic sequence.
3).Uranium loses half of its weight every 415 years.
Exponential decay in every 415 years. So geometric sequence with a common ratio of 1/2.
4).A family of rabbits doubles in size every 3 months.
Exponential series again so geometric sequence with a common ratio of 2.
5).Car drives at a constant speed of 58 mph.
Its a linear function representing an arithmetic sequence with a common difference of 58 mph.
6). Number of students increases by 122 every year.
An arithmetic sequence with a common difference of 122.
7). Number of pieces of chalk in a class room decreases by 10 throughout the school year.
It's an arithmetic sequence having common difference of 10.

Light ray 1 strikes the smooth surface, separating air and water as shown below.
A horizontal line is drawn and the part above the line is labeled Air and the part below the line is labeled Water. There is one slanting ray labeled 1 which falls on the line at a point and there are four rays of light labeled 2, 3, 4, and 5 which move away from same point on the line. Ray 5 is exactly vertical to the line and below the line, ray 4 is on the right of ray 5 and makes an angle of about 25 degrees with ray 5. Ray 3 is above the line and makes an angle of about 25 degrees with the line. Ray 2 is on the right of ray 1 and ray 1 and ray 2 make angles of about 25 degrees with the vertical at the point where ray 1 strikes.
Which of the following rays is the part of ray 1 that is reflected from the smooth surface?
Ray 2
Ray 3
Ray 4
Ray 5
Answer:
Ray 2 is the answer

π, 22/7, 3.14, 355/113, 3 141/1000
Answer:
[tex]\frac{335}{113} < 3.14 < 3\frac{141}{1000} < \pi[/tex]
Step-by-step explanation:
Set of Data: [tex]\pi[/tex], [tex]3.14[/tex], [tex]\frac{335}{113}[/tex], [tex]3\frac{141}{1000}[/tex]
To order them from smallest to largest:

Example
A statistical question is a question that can be answered by collecting data that vary. For example, “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question.
Try to solve the problem now.
The correct statistical question is,
''What are the speeds of the cars on the highway?''
Hence, Option B is true.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Now, By all the statements we get;
The statistical question is,
B. "What are the speeds of the cars on the highway?"
Since, it involves collecting data on a variable of interest (speed) from a group of individuals (cars on the highway).
Thus, Option B is true.

Answer:
172,438
Step-by-step explanation:
The number of total doctors should be a bigger number than the number of female doctors.
Let x = the total number of doctors
x • 28.3% = 48800
Change the % to a decimal for the calculations.
.283x = 48800
Divide by .283
x = 172438
The total number of registered doctors is 172,438

Answer:
1372 cm^3
Step-by-step explanation:
To find the volume, you need to multiply height, length and width. In this question they are all given to us, so we just need to do the following:
volume = height*length*width
= 9 1/3cm*21cm*7cm (note that 9 1/3 could be simplified to 28/3)
= 1372 cm^3
We put ^3 at the end to show that it's a volume/3D.
I hope you can understand this :)
Answer: 1372
Step-by-step explanation:
Volume= length x width x height
Length= 21 cm
Width= 7 cm
Height= 9 1/3 cm
Multiply
21 x 7 x 9 1/3
147 x 9 1/3
* Note you can NEVER multiply mixed numbers like 9 1/3, so we have to make them improper.*
9 1/3 = 28/3
147 x 28/3= 4116/3
4116/3= 1372

Step-by-step explanation:
Check it yourself. It’s pretty easy. :)
A teacher surveyed her class after they had taken a vocabulary test. Eighteen of the students claimed they had studied at least one hour for the test. The remaining twelve students admitted that they had not studied for the test at all. The test results (expressed as a percent) for the two groups are shown below.
Studied: 88, 100, 94, 79, 92, 100, 95, 83, 89, 99, 100, 91, 89, 95, 100, 93, 96, 84
Did Not Study: 82, 72, 45, 91, 58, 83, 65, 87, 90, 77, 73, 89
Calculate the range and interquartile range for each set of data.
Using complete sentences, compare the data sets based on your results in part A.
ANSWER TO QUESTION
Part A
Studied : 79, 83, 84, 88, 89, 89, 91, 92, 93, 94, 95, 95, 96, 99, 100, 100, 100, 100
Range : 21
Interquartile range : 99.5 - 89 = 10.5
Did not study : 45, 58, 65, 72, 73, 77, 82, 83, 87, 89, 90, 91
Range : 46
Interquartile range : 89 - 65 = 24
Part B
The students that claimed to study had a lower range and interquartile than the students that did not study. Range difference between the students that did not study vs the students that did study, 46 > 21. Interquartile range difference between the students that did not study vs the students that did, 24 > 10.5.

What is the best estimate for this sum?
1/4+2/7
The sum will be close to 1/4.
The sum will be close to 1/2.
The sum will be close to 1.
Answer:
The sum is close to 1/2
Step-by-step explanation:
1/4 = 7/28
2/7 = 8/28
7/28 + 8/28 = 15/28
14/28 = 1/2 and 15/28 is close to 14/28
