What is the probability of rolling a six on a fair die?
Answer: 1/6
Step-by-step explanation: To find the probability of rolling a six,
let's use our ratio for the probability of an event.
number of favorable outcomes / total number of outcomes
Since only one side of a die has a six on on it, the number of favorable
outcomes for rolling a six is 1 and since there are six sides to a die and it's
equally likely that the die will landy on any of these sides, the total number
of outcomes is 6.
So the probability of rolling a six is 1/6.

Mean:
Median:
Mode:
Answer:
1. Mean = 55.8
Median = 23
Mode = None
2. Mean = 2.1
Median = 1.4
Mode 0.5
3. Mean = 4.5
Median = 4.5
Mode = 1,4, 5, 8
4. Mean 68
Median 58
Mode = 0
Step-by-step explanation:
Mean = 17 + 25 + 23 + 200 + 14 / 5 = 279/5 = 55.8
Median= Because its odd you put them in order 17, 14, 23, 25, 200 = 23 because it is the middle number. Mode = None
2. Mean = 0.5 + 1.4 + 3.0 + 7.0 + 0.5 +1.8 + 0.5 = 14.7 = 14.7/7 = 2.1
Median = because it is odd you put them in order 0.5, 0.5, 0.5, 1.4, 1.8, 3.0, 7.0 = 1.4 The mode is 0.5 because it repeats three times
3. Mean = 1 + 8 + 5 + 4 + 1 + 8 + 5 + 4 = 36/8 =4.5
Median = Because its even you divide by the two middle numbers = 1, 1, 4,4, 5, 5 , 8 , 8 = 4+5 = 9/2 = 4.5 Mode = 1, 4, 5, and 8 are the numbers that are repeated most often.
Mean = 0+78+99+58+65+0+47+38+227 = 68 Median, Because there is an odd number you get the odd number from the middle. 0, 0, 38, 47, 58, 65, 78, 99, 227 = 58 Mode = 0 because it repeats more often.

Find the pattern. What numbers come next?
61, 54, 47, 40,
Answer:
33
Step-by-step explanation:
It's decreasing by 7
The relation is the descending the series by 7 and the next term is 33.
We have to determine, find the pattern and what numbers come next
We have given that, 61, 54, 47, 40.
What is the series?
A series is, roughly speaking, a description of the operation of adding infinitely many quantities, one after the other.
61-54=7
54-47=7
47-40=7
So the next term is
40-7=33
Therefore the relation is the descending the series by 7 and the next term is 33.

The temperature was -13 °F and then fell 5 degrees.
What was the final temperature?
Answer:
-8
Step-by-step explanation:
The final temperature was -18 °F if it decreased by 5 degrees.
What is the addition operation?The addition operation in mathematics adds values on each side of the operator.
For example 4 + 2 = 6
The temperature was -13 °F and then dropped 5 degrees.
As per the question, we have data as follows:
The initial temperature = -13 °F
The changed temperature = -5 °F (negative sign indicates temp dropped)
Final temperature = initial temperature + changed temperature
Final temperature = -13 °F + (-5 °F)
Final temperature = -13 °F - 5 °F
Apply the addition operation, and we get
Final temperature = -18 °F
Therefore, the final temperature was -18 °F.

:)))))))))))))))))))Louis wants to carpet the rectangular floor of his basement. The basement has an area of 4,335 square feet. The width of the basement is
3/5 its length. What is the length of Louis's basement? The length is blank feet.
Answer:
The length of Louis's basement is 85 feet.
Step-by-step explanation:
The area of the basement, A = 4,335 square feet
The width of the basement is 3/5 its length.
Let length be l.
Width = (3/5)l
The area of the basement is given by :
[tex]A=l\times b\\\\4,335 =l\times \dfrac{3}{5}l\\\\4,335 =\dfrac{3}{5}l^2\\\\l^2=\dfrac{4,335 \times 5}{3}\\\\l=\sqrt{\dfrac{4335\times5}{3}}\\\\l=85\ ft[/tex]
So, the length of Louis's basement is 85 feet.
Factor the following: 7a+ 3
Answer:
