Answer:
Sorry if I’m wrong but is it ... 90???
Step-by-step explanation:
========================================================
Work Shown:
The given list is {95, 89, 99, 85, 82, 81, 99}
Sort this list from smallest to largest.
We then have this: {81, 82, 85, 89, 95, 99, 99}
Next we will erase the first and last items in that sorted list above
Doing so leads to this smaller list: {82, 85, 89, 95, 99}
Repeat the step from before. Erase the first and last items
We now have {85, 89, 95}
One more time lets erase the first and last items getting {89}
This shows that 89 is the very center item
Going back to {81, 82, 85, 89, 95, 99, 99} we see that 89 is at the center with three items below it (81,82,85) and three items above it (95,99,99)
Therefore, the median is 89.
----------------------------------
Another route to take is to count the number of items in {81, 82, 85, 89, 95, 99, 99}. You should count 7 items.
Add 1 and divide by 2 to get (7+1)/2 = 8/2 = 4
The median is in slot 4, which is exactly where 89 is located in the list {81, 82, 85, 89, 95, 99, 99}
Note: this trick only works if you have an odd number of items in a set.

The cost of a speeding ticket is a function of each mile per hour that exceeds the speed limit multiplied by a fixed rate of $2 plus a $40 processing fee.Write the function that represents this relationship.Then determine the cost of a speedingticket for a car that has gone 50 mph in a 35 mph zone
Answers
The cost of the speeding ticket for a car that has gone 50 mph in a 35 mph zone is $70.
Describe Function?In mathematics, a function is a relationship between two sets of numbers, known as the domain and the range, that assigns each element of the domain a unique element in the range. A function can be thought of as a machine that takes input from the domain and produces output in the range.
More formally, a function f from a set X to a set Y is denoted as f: X → Y
For example, the function f(x) = 2x assigns to each real number x a unique real number 2x. When x = 1, f(1) = 2; when x = -3, f(-3) = -6.
Functions can be represented in a variety of ways, including algebraic expressions, tables of values, and graphs. The graph of a function is a visual representation of the relationship between the input and output values, and can be used to analyze the behavior of the function.
Functions are important in many areas of mathematics, science, and engineering, and are used to model relationships between quantities, solve problems, and make predictions. They are also used in computer programming, where they are used to encapsulate behavior and modularize code.
The function that represents the relationship between the speed of a car and the cost of a speeding ticket can be expressed as:
C(x) = 2(x - L) + 40
where:
C(x) is the cost of the speeding ticket for a car traveling at speed x (in mph).
L is the speed limit (in mph).
(x - L) represents the number of miles per hour over the speed limit that the car was traveling.
The fixed rate is $2 per mile per hour over the limit, and there is a $40 processing fee added to every ticket.
To determine the cost of a speeding ticket for a car that has gone 50 mph in a 35 mph zone, we substitute the values for x and L into the formula above:
C(50) = 2(50 - 35) + 40
C(50) = 2(15) + 40
C(50) = 30 + 40
C(50) = $70
Therefore, the cost of the speeding ticket for a car that has gone 50 mph in a 35 mph zone is $70.

After 22 games, JD Drew has 32 hits. After 36 games he has 60 hits. Write a linear equation in slope intercept form to describe the situation. How many hits with JD Drew have after 50 games
Answers
Answer:
JD Drew will have 88 hits after 50 games
Step-by-step explanation:
Linear Modeling
It consists of modeling real-life situations by a function whose graph is a straight line.
The equation of a line can be expressed as:
h=m.g+b
h=number of hits JD Drew has
g=number of games
m,b= constant values
The problem provides two conditions: after 22 games, JD Drew has 32 hits. This is the point (22,32). Also, it has been given after 36 games he has 60 hits. This is the point (36,60).
Substituting the ordered pairs given, we have:
32=m.22+b
60=m.36+b
Subtracting both equations:
60 - 32 = 14m
28 = 14m
Solving:
m = 2
Using the first equation:
32 = (2)*22+b
32 = 44 + b
Solving:
b = -12
The model is now complete:
h = 2g - 12
Finally, calculate the number of hits for g=50 games:
h = 2*50 - 12
h = 100 - 12 = 88
JD Drew will have 88 hits after 50 games

Which transformation can be used to show that LMN is similar to PQR?
A. Dilation, reflection
B. Reflection, translation
C. Rotation, dilation
D. Translation, rotation
Answers
Explanation:
Rotations, reflections and translations are known as rigid transformations; this means they do not change the size or shape of a figure, they simply move it. These rigid transformations preserve congruence.
Dilation, however, are not rigid transformations, since they change the size of a shape. Dilation would not change the shape, just the size; the angle measures would be the same, and the ratio of corresponding sides would be equal to the scale factor used in the dilation. This would give us a similar, but not congruent, figure.

A type of mold doubles every 9 hours. If you started with 14 spores in a Petri dish, how many spores would you have after 45 hours? After 45 hours, there would be_______spores.
Answers
Answer:
448
Step-by-step explanation:
Every 9 hours, mold doubles
Started with 14 spores
In 9 hours, 14+14= 28 spores
In 18 hours, 28+28=56 spores
In 27 hours, 56+56=112 spores
In 36 hours, 112+112=224 spores
In 45 hours, 224+224=448 spores
We want to write an equation for an exponential growth that represents the change in the population of mold.
The answer is: "After 45 hours, there would be__448__spores."
-----------------------------------
We know that a given type of mold doubles every 9 hours.
So if you start with a quantity A of spores, after 9 hours there are:
2*A spores.
After another 9 hours (for a total of 18 hours) the population is:
(2^2)*A spores.
You already could see the pattern.
After x hours, the number of spores will be given by:
p(x) = A*(2)^(x/9)
Now we want to know how many spores are there after 45 hours, if the initial amount is 14 spores.
So we need to replace:
A = 14x = 45Then we want to compute:
p(45) = 14*(2)^(45/9) = 448
From this, we can conclude that after 45 hours there will be 448 spores.

Barnes and noble needs to ship 14 mystery books, 12 science-fiction books, and 8 historical-fiction books. The store can only pack one genre of book in each box, and they must pack the same number of books in each box. What is the greatest number of books Barnes and Noble can pack in each box?
Answers
Answer: 2
Step-by-step explanation:
Given: 14 mystery books, 12 science-fiction books, and 8 historical-fiction books needs to b shipped.
If they want to pack one genre of book in each box such that they pack same number of books in each box.
Then, the greatest number of books Barnes and Noble can pack in each box
= GCD(14,12,8)
Since, 14 = 2 x 7
12 = 2 x 2 x 3
8 = 2 x 2 x 2
GCD(14,12,8)=2
Hence, the greatest number of books Barnes and Noble can pack in each box = 2
