Answer:
45¹³/₁₀₀
Step-by-step explanation:
The average number of hourly visitors to an art exhibit is 45.13.
We are required to write the average number of hourly visitors as a mixed number.
45.13=45+0.13
0.13=13/100 in its simplest form.
Therefore:
45.13=45+13/100
Writing this as a mixed number, we have:
45.13= 45¹³/₁₀₀
Therefore the average number of hourly visitor is given by 45¹³/₁₀₀
The median of the date is 5
Answer:
(2, -4).
Step-by-step explanation:
x^2 - 4x
= (x - 2)^2 - 4.
So the vertex is at
(2, -4).
Answer: E. none of the above
Step-by-step explanation:
The given data values that represents the population:
2, 6, 3, and 1.
Number of values : n=4
Mean of the data values =
Sum of the squares of the difference between each values and the mean =
Now , Variance = (Sum of the squares of the difference between each values and the mean ) ÷ (n)
= (14) ÷ (4)= 3.5
Hence, the variance is 3.5.
Therefore , the correct answer is "E. none of the above".
