Step-by-step explanation:
Mean of a data-set
The mean of a data-set is the sum of all values in the data-set divided by the number of values.
The mean temperature for the first 4 days in January was 1°C.
This means that during the first 4 days, the sum of the temperatures was 4*1 = 4ºC.
The mean temperature for the first 5 days in January was -1°C.
First 4 days: Sum of 4º
5th day: Temperature of x.
The mean is -1, so:
The temperature on the 5th day was of -9ºC.

Answer:
1 : 6
Step-by-step explanation:
The given scale factor is ...
2 in : 1 ft
To express this as a ratio of pure numbers (without units), the units must be the same on either side of the colon (:). Here, we can make that happen by changing 1 ft to its equal in inches: 12 inches.
2 in : 1 ft = 2 in : 12 in = 2 : 12 = 1 : 6
We generally like to have the scale factor reduced to lowest terms, so we want to remove any common factors from the numbers.
The scale factor of 2 in to 1 foot is 1 : 6.
