First, you have to round the .1, which would be .0. Next, you round 19.0, or just 19, to the nearest 10, which is 20. Therefore, 19.1 rounded to the nearest 10 is 20.
Answer: =11x−8
Step-by-step explanation:
Distribute:
=(3)(x)+(3)(−2)+(2)(4x)+(2)(−1)
=3x+−6+8x+−2
Combine Like Terms:
=3x+−6+8x+−2
=(3x+8x)+(−6+−2)
=11x+−8
Yes. Supplementary angle is one which when added to the angle makes 180 degrees. Thus, if the angle is acute, its supplementary angle would be obtuse.
The standard error of the mean is 12.
The standard error of the mean points to the standard deviation of the distribution of a sample mean obtained from a population.
The standard error S.E of the mean can be calculated by using the formula:
where;
- standard deviation = 24
- sample size n = 4
S.E = 12
