25 - 15 = 10. You have 10 words left to memorize.
I hope this helps.
X - y = 5,
x = 5 + y
substitute (x = 5 + y) into the first equation,
5 + y + 2y = -1
3y = -6
y = -2,
substitute y = -2 into (x - y = 5),
x + 2 = 5
x = 3
Hence, x = 3, y = -2
Given:
<span>random sample of 520 adults
mean was 150
standard deviation was 4.5.
reported with a 95% confidence level, and the confidence interval for the study was 150 ± 0.39.
The range of </span><span>values that shows the confidence interval for the study is </span><span>149.61 to 150.39
150 + 0.39 = 150.39
150 - 0.39 = 149.61</span>
