You need to get x by itself. Add 6 to both sides.
x = 14
Answer: 23
4x4=16 ( it represents the four weeks and the four inch growth each week)
Now just do 16+7 which equals to 23
The best estimate of the population means is always the sample mean. We have the sample values, using them we can find the sample mean.
The sum of the sampled rates = 248
Sample Size = 10
Mean value of the sample = Sum of Sample Rate/Sample Size
So,
Mean of the sample = 248/10 = 24.8
Therefore, we can say that the best estimate for the population mean is 24.8
To rotate a point around the origin by 180 degrees, multiply both parts of the coordinate point by 
. (This means you go from 
to 
.)
