Answer: mean =54.69
Median = 61.5
There is no mode
Step-by-step explanation:
Mean is calculated as sum of values in a data set/ number of values in a data set.
Given the data set above,
mean=54.6+45.98+67.4+55.6+45.7+58.9/6
=328.18/6
Mean= 54.69
Median is the midpoint of the values in a data set. For an even data set, however, median is the sum of two middle values divided by two.
To find the median, we sum the two most middle values= 67.4 and 55.6; then divide by two
Median = 67.4 + 55.6/2
= 123/2
Median = 61.5
Mode is the value with the highest occurrence in a data set. In the given data set, there is no mode, as all data values appear once.
I hope this is clear, please mark as brainliest answer.
Answer:
3, -11-3
Step-by-step explanation:
(3x+1\)^2-100=0
(3x+1)^2-100+100=0+10
(3x+1)^2=100
3x+1=sqrt{100}
3x+1=-sqrt{100}
I’m think the answer is 28
Answer:
(a) MAE = 5.20
(b) MSE = 10
(c) MAPE = 38.60%
(d) Forecast for week 7 = 14
Step-by-step explanation:
Note: See the attached excel for the calculations of the Error, Error^2, and Error %.
(a) mean absolute error
MAE = Total of absolute value of error / Number of observations considered = |Error| / 5 = 26 / 5 = 5.20
(b) mean squared error
MSE = Total of Error^2 / Number of observations considered = Error^2 / 5 = 150 / 5 = 10
(c) mean absolute percentage error (Round your answer to two decimal places.)
MAPE = Total of Error % / Number of observations considered = Error % / 5 = 193.02 / 5 = 38.60%
(d) What is the forecast for week 7?
Since the forecast is based on the naive method (most recent value), the forecast for week 7 is value for week 6. Therefore, we have:
Forecast for week 7 = 14

there is no division symbol on laptops, but you could either search it up and copy and paste it or write it as a fraction
