A cell phone company charges an initial price of $500 for a new phone and then $60 each month after the purchase. if c (t) is a rational function that represents the average monthly cost of owning the cell phone, what is the range of the function? (2 points) r: (0, 500) r: (60, 560) r: ℠r: (−[infinity], [infinity])
The range of the given function is: (500, ∞).
What is the range of a function?The collection of potential output values for a function is known as its range.
Now,
Given:
Initial price of the cell phone = $500Monthly charge = $60Let 't' be the number of months. Then, the function C(t) can be calculated as:
C(t) = 500 + 60t
For range:
The minimum value will be when t = 0, i.e., when no charge has been charged by for each month.
Thus, C(0) = 500 + 60(0)
=> C(0) = 500
The maximum value will be when t = ∞, i.e., for infinite number of months.
=> C(∞) = 500 + 60(∞)
=> C(∞) = 500 + ∞
=> C(∞) = ∞
Thus, the range of the function will be: (500, ∞).

you perform an experiment to determine how many breaths a fish takes per minute. your experiment yields the following data: minute 1:65 breaths; minute 2:73 breaths; minute 3:67 breaths; minute 4:71 breaths; minute 5:62 breaths. calculate the average number of breaths that a fish takes per minute.
The average breaths taken per minute by the fish is 22.53. This is obtained using the previous knowledge of average.
What do you mean by average?
An average is a single number that is used to represent an entire group of things. Averages are calculated by dividing the sum of all values by the total number of values.
Calculation of average number of breaths taken by a fish per minute
Given:
Breaths in 1 minute are 65
Breaths in 2 minutes are 73
Breaths in 3 minutes are 67
Breaths in 4 minutes are 71
Breaths in 5 minutes are 62
Total breaths = 65 + 73 + 67 + 71 + 62
= 338
Total time taken = 1 + 2 + 3 + 4 +5
= 15 minutes
The average number of breaths = total breaths / total time taken
= 338 / 15
= 22.53 breaths per minute
Hence, the average breaths taken per minute by the fish is 22.53.

the first possession of each nfl game is decided by a coin toss. is this process deterministic, or truly random?
A coin toss determines the first possession of each NFL game. This process deterministic not random event because the initial coin flip only determines whether a team receives the ball now at start of the first or third quarter.
What is meant by first possession?Possession in football refers to a team keeping possession of the ball for as longer as possible in order to create opportunities for goals and prevent this same opposition from posing a threat to the team's goal.
Some key features regarding the first possession in NFL game are-
The scoring team wins if the first possession results in such a touchdown (by receiving team or a defensive team on a turnover) or a safety by the defensive team. If the receiving team is unable to score and loses possession, this same game is decided by sudden death, with the first team to score winning.Many NFL fans oppose the current overtime setup in which the winning team can elect to catch the ball, move down the field, and score, effectively ending the game without allowing the opposing team to touch the ball on offense.If the resolution of player decisions results in completely predictable outcomes, the game is deterministic. It is indeterministic to some extent if actions result in potentially chaotic outcomes.To know more about the random events, here

if 6 bales are needed to feed 40 head of cattle, how many bales are needed to feed 50
Your question was incomplete. Please refer the content below:
If 6 bales are needed to feed 40 head of cattle, how many bales are needed to feed 50 head of cattle?
By using unitary method, we get that 7.5 bales are need to feed the 50 heads of cattle.
We are given that:
6 bales are need to feed the 40 heads of cattle.
We need to find out that how many bales will be needed to feed the 50 heads of cattle.
Here, we will be using the unitary method.
So, 40 heads need = 6 bales
1 head needs = 6/40 bales
1 head needs = 3 / 20 bales.
So, 50 heads will need:
50 heads will need = 3 / 20 × 50 bales
50 heads will need = 3 / 2 × 5 bales
50 heads will need = 7.5 bales.
Therefore, by using unitary method, we get that 7.5 bales are need to feed the 50 heads of cattle.

The second one is a function.
Step-by-step explanation:
The other 3 have one-to-many mappings.
For example the first relation has 1 mapping to 2, 3, 4 and 5.
The range of the transformation function f(x,y)= (x+5,y-8) is (10,8), (-2,7), and (7,9) which point is in the domain
We get that the domain will be {-7, 2, 5}.
We are given a transformation function:
f ( x , y ) = ( x + 5 , y - 8 )
Also, we are given the points in this transformation function as:
(10, 8), (-2, 7) and (7, 9)
Now, we have to find the point that lies in the domain of the function.
We have:
x + 5
Also, the values of x + 5 are given as 10, -2 and 7.
For (10, 8)
x + 5 = 10
x = 10 - 5
x = 5
For (-2, 7)
x + 5 = -2
x = - 2 - 5
x = - 7
For (7, 9)
x + 5 = 7
x = 7 - 5
x = 2
So, domain is {-7, 2, 5}.
Therefore, we get that the domain will be {-7, 2, 5}.

Answer:
Cohesion and Adhesion. The complementary action of these two forces allows water to rise in a narrow capillary tube such as the xylem tissues of plants.
Step-by-step explanation:
Cohesion: the water molecules attract each other and are responsible for the surface tension of water.
Adhesion: the water molecule is also able to attract other non-water molecules. This allows water to be able to ‘cling’ to the sides of a capillary tube.
The complementary action of these two forces allows water to rise in a narrow capillary tube such as the xylem tissues of plants.

In 2006, the population of the country was 33.3 million. This represented an increase in population of 6.5% since 2001. What was the population of the country in 2001? Round to the nearest hundredth of a million.
The population of the country in 2001 to the nearest hundredth of a million is 24.31 million
What was the population in 2001?If the population grows by 6.5% every year, the population grows at a compound rate. The equation that can be used to determine the population in 2001 would be an exponential equation. The equation that can be used to represent an exponential equation is: a = [tex]mx^{b}[/tex]
When a population grows at a compound rate, it means that both the existing population and the increase in the population increase by 6.5 every year.
The equation that can be used to determine the population of Tacoma in 2017 is:
P = FV / (1 + r)^n
Where:
FV = Future value P = Present populationR = rate of growthN = number of years : 2006 - 2001 = 533.3 / ( 1 + 0.065)^5
33.3 / (1.065^5) = 24.30503 million
In order to round 24.30503 million to the nearest hundredth , look at the thousandth figure, if it is greater or equal to 5, add one to the hundredth digit and change the thousandth digit to 0. So, 24.30503 million becomes 24.31 million

1. Which set of numbers has the largest variance?
a. 7, 8, 9, 10
b. 1, 3, 4, 7
c. 4, ?2, ?1, 0
d. 1, 0, 2, 4
2. What is the population variance of the following set of numbers: 3, 5, 8, 9, 10?
a. 29
b. 6.8
c. 7
d. 8.5
1) 1,3,4,7 dataset has the highest variance.
1. How to find the largest variance of given set of numbers?Variability is measured by the variance. The average of the squared deviations from the mean is used to calculate it. The degree of spread in your data set is indicated by variance. The variance is greater in respect to the mean the more dispersed the data.
to find the variance,
first step is to calculate the mean Next, take each data point and square the difference after subtracting the mean. All values' squared differences are added. Next, divide the total by the number of data points. this is the process to get the variance.
a) now given that a. 7, 8, 9, 10
[tex]mean = \frac{sum \: of \: al l\:data \: points \: }{ total \: number \: of \: data\: points \: } [/tex]
[tex]mean = \frac{(7 +8 + 9 + 10) }{4} [/tex]
mean = 8.5
now, take each data point and square the difference after subtracting the mean.
[tex](7 - 8.5) {}^{2} = 2.25 \\ (8 - 8.5) {}^{2} = 0.25 \\ (9 - 8.5) {}^{2} = 0.25 \\ (10 - 8.5) {}^{2} = 2.25[/tex]
All values' squared differences are added.
2.25+0.25+0.25+2.25=5
Next, divide the total by the number of data points.
5/4 = 1.25
Hence the variance of 7,8,9,10 is 1.25
b) given that 1,3,4,7
mean = 3.75
variance = 18.75/4 = 4.68.
Hence the variance of 1,3,4,7 is 4.68
c) given that 4,2,1,0
mean= 1.75
variance= 2.1875
Hence the variance of 4,2,1,0 is 2.1875
D) given that 1,0,2,4
mean= 1.75
variance= 2.1875
Hence the variance of 1,0,2,4 is 2.1875
Therefore 1,3,4,7 dataset has the highest variance.
