I believe that the scale factor is 7. Hope I helped!
Scientific notation is usually written in powers of tens, in this case:
According to PEMDAS, the parentheses would go first.
3+1 = 2
42/2=21

Answer:
the mean and standard deviation is 2300 and 100 respectively
Step-by-step explanation:
Given that
Mean = 2300
Standard deviation = 500
let us assume the x be the mean of living space
And, the sample is of 25 homes
We need to find out the mean and the standard deviation
So here mean = 2300
And, the standard deviation
= 500 ÷√25
= 500 ÷ 5
= 100
hence, the mean and standard deviation is 2300 and 100 respectively
The answer is y = 8 from the photo
