Answer:
B.
Mean: 16.1
Median: 16
Mode: 16
Step-by-step explanation:
First, order the numbers in the data set from least to greatest:
[tex]14 , 14 , 14 , 14 , 15 , 15 , 15 , 15 , 15 , 16 , 16 , 16 , 16 , 16 , 16 , 17 , 17 , 17 , 19 , 19 , 19 , 19[/tex]
First, find the mean. The mean of a data set can be found by adding all the numbers together and dividing by the amount of numbers in the set:
[tex]\frac{14 + 14 + 14 + 14 + 15 + 15 + 15 + 15 + 15 + 16 + 16 + 16 + 16 + 16 + 16 + 17 + 17 + 17 + 19 + 19 + 19 + 19}{22} = \frac{354}{22}[/tex]
Next, simplify by dividing:
[tex]\frac{354}{22} = \frac{177}{11} = 16 \frac{1}{11} or ~16.1[/tex]
Mean: 16.1
Next, find the median. The median is the number(s) directly in the middle. If there is a even amount of number in the data set, find the mean of the two median numbers:
Median: 16 , 16
Median = [tex]\frac{16 + 16}{2} = \frac{32}{2} = 16[/tex]
Median = 16
Next, find the mode. The median is the number that shows up the most. In this case, it is 16, which appears 6 times, 1 more time then the next number that appears the most 15, which appears 5 times.
Mode: 16

The population of a certain inner-city area is estimated to be declining according to the model P(t)=259,000e−0.012t, where t is the number of years from the present. What does this model predict the population will be in 13 years? Round to the nearest person.
Answer:
259000 people
Step-by-step explanation:
Since t is the number of years, you sub 13 into the equation as t,
P(13)=259,000e−0.012(13)
= 258999.844 (round since its people --> 259000)

How can you use dilations to solve real world problems?
You can use dilations when drawing blueprints to.......
scale, move or rotate? Which one is it?
Dilation is used in eye exams so that the eye doctor can view the patient's eye better. After a while it will slowly reduce in size and return back to normal.
A microscope dilates a specific specimen four times larger. A microscope, a projector, a model boat, or a model of a city. All of these use dilation..

An ice cream cone has a diameter of 3 inches and a height of 6 inches. How much ice cream can just the cone hold?
Answer:
14.13 cubic inch
Step-by-step explanation:
volume=(π x r^2 x h) divided by 3
Volume=(3.14x(1.5)^2x6) divided by 3
Volume=(3.14x1.5x1.5x6) divided by 3
Volume=42.39 divided divided by 3
Volume=14.13
Volume=14.13 cubic inch
The population sizes of many animal species rise and fall over time. Suppose that the population size of a certain species can be modeled by the following.
[tex]p(t) = 4096 - 1269cos(\frac{2\pi }{11} t)[/tex]
In this equation, p(t) represents the total population size and t is the time (in years). Suppose we start at t = 0 years.
During the first 11 years, when will the population size be 4700?
Do not round any intermediate computations, and round your answer(s) to the nearest hundredth of a year. (If there is more than one answer, enter additional answers with the "or" button.)
There are two answers
Solving the trigonometric equation, it is found that during the first 11 years, the population size will be of 4700 in 3.62 and 7.24 years.
What is the trigonometric equation for the population?It is given by:
[tex]p(t) = 4096 - 1269\cos{\left(\frac{2\pi}{11}t\right)}[/tex]
It will be of 4700 when p(t) = 4700, hence:
[tex]p(t) = 4096 - 1269\cos{\left(\frac{2\pi}{11}t\right)}[/tex]
[tex]4700 = 4096 - 1269\cos{\left(\frac{2\pi}{11}t\right)}[/tex]
[tex]604 = - 1269\cos{\left(\frac{2\pi}{11}t\right)}[/tex]
[tex]\cos{\left(\frac{2\pi}{11}t\right)} = -\frac{604}{1269}[/tex]
[tex]\cos{\left(\frac{2\pi}{11}t\right)} = -0.47596532702[/tex]
[tex]\cos^{-1}{\cos{\left(\frac{2\pi}{11}t\right)}} = cos^{-1}{-0.47596532702}[/tex]
Then:
[tex]\frac{2\pi}{11}t = 2.06685766[/tex]
[tex]t = \frac{11 \times 2.06685766}{2\pi}[/tex]
[tex]t = 3.62k, k = 1, 2, ...[/tex]
Thus:
t = 3.62 x 1 = 3.62
t = 3.62 x 2 = 7.24.
The population size will be of 4700 in 3.62 and 7.24 years.

The coach for a basketball team wants to buy new shoes for her 12 players.
Super Sports is offering a 20% discount on each pair of shoes, which were originally
priced $72.50. A 6.5% sales tax will be applied to the discounted price.
The same shoes are also available on Double Dribble's web site for $54.75. A
9% processing fee will be applied to the cost of the shoes, plus a shipping fee of
$5.99 for each pair.
What is the difference in the total costs of the 12 pairs of shoes between the two
stores?
Using proportions, it is found that the difference in the total costs of the 12 pairs of shoes between the two stores is of $46.77.
What is a proportion?A proportion is a fraction of a total amount.
At Super Sports, each pair of shoes costs $72.50, with a discount of 20%(multiplication by 0.8) and a sales tax of 6.5%(multiplication by 1.065). Hence, the total cost of the 12 pairs is given by:
Cs = 12 x 72.50 x 0.8 x 1.065 = $741.24.
At Double Dribble, each shoe costs $54.75, plus a 9% processing free(multiplication by 1.09), plus a shipping fee of $5.99 for each pair, hence the total cost is given by:
Cd = 12 x (1.09 x 54.75 + 5.99) = $788.01.
The difference is given by:
$788.01 - $741.24 = $46.77.

Answer:
Let's say a factor in the watercycle is vegetation. Deforestation leads to less vegetation which means less transpiration which affects how the water reenters the atmosphere. In addition, the trees can no longer catch water in their leaves, absorb it, or filter pollutants through their roots before it runs off into say a local body of water.

The time it take the ball to reach 156feet above the ground level is 0.5 secs and 5.5 seconds
Functions and valuesGiven the height of the ball expressed by the function below;
h = -16t^2 + 96t + 112
where
t is the time in seconds
If the car is 156ft above the ground, hence
Substitute
-16t^2 + 96t + 112 = 156
Multiply through by -1
16t^2 - 96t - 112 = -156
16t^2 - 96t - 112 + 156 = 0
16t^2 - 96t + 44 = 0
4t^2 - 24t + 11 = 0
Factorize
On factorizing, the positive value of "t" is 0.5 secs and 5.5 seconds
Hence the time it take the ball to reach 156feet above the ground level is 0.5 secs and 5.5 seconds
