Answer:
<em>No mode</em>
<u>Skills needed: Mode (Frequency) </u>
Step-by-step explanation:
1) The mode of a set of numbers is the number that appears the greatest number of times.
Example: In the set --->
is the mode since 8 appears 2 times, while the other numbers only appear once.
There are 2 special cases
---> One is where there is more than one mode: (5 and 3 are both modes in this set)
---> Another is where there is no mode () ---> No number appears more than the other numbers.
We are given a dataset of: and have to find the mode.
2) As you can see, there are no numbers repeated (all of the numbers only appear once)
This means there is no mode.

Answer:
Perimeter is 17.07
Step-by-step explanation:
We know that DF = EF = 5 cm, since D and E are the midpoints of AC and AB, both of which are 10 cm in length.
We need to use the Pythagorean theorem to get the length of DE.
So the perimeter of DEF is 5 + 5 + 7.07 = 17.07
Let
x-------> the number of game tokens purchased for a member of the arcade
y-------> the function of the yearly cost in dollars
we know that
the function y of the yearly cost in dollars is equal to
This is the equation of the line
using a graph tool
see the attached figure
<u>Statements</u>
<u>case a)</u> The slope of the function is $1.00
The statement is False
The slope of the function is equal to
<u>case b)</u> The y-intercept of the function is $60
The statement is True
we know that
The y-intercept of the function is the value of the function when the value of x is equal to zero
so
for
<u>case c)</u> The function can be represented by the equation y =(1/10)x + 60
The statement is True
The equation of the function is equal to
<u>case d)</u> The domain is all real numbers
The statement is False
The value of x cannot be negative, therefore the domain is the interval
[0,∞)
<u>case e)</u> The range is {y| y ≥ 60}
The statement is True
The range of the function is the interval-------> [60,∞)
see the attached figure
