Answer:
When the online site surveyed about how many times per week the user plays any video game online, the mean was 154. When Thomas surveyed individually to first 50 persons, he got the mean 20.
Now, if Thomas wants that his statistical results should be more accurate and inline than the statistical results, he need to increase the samples Like 100-200 people. As the sample increases, the statistical results are more accurate.
Answer:
.026
Step-by-step explanation:
So you’re trying to get the a on it’s own while you use +-x/ operations.
For this one you divide both sides by 2 to get the a alone.
2a/2=12/2
a=6
Answer:
(x - 8)² + (y + 2)² = 289
Step-by-step explanation:
Assuming you require the equation of the circle.
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (8, - 2) and r = 17, thus
(x - 8)² + (y - (- 2))² = 17², that is
(x - 8)² + (y + 2)² = 289 ← equation of circle
