Two or more lines are parallel when they lie in the same plane and never intersect. The symbol for parallel is <span>||</span>. To mark lines parallel, draw arrows <span>(>)</span> on each parallel line. If there are more than one pair of parallel lines, use two arrows <span>(<span>>></span>)</span> for the second pair. The two lines below would be labeled <span><span><span>AB</span><span>←→</span></span> || <span><span>MN</span><span>←→−</span></span></span> or <span>l || m</span>.
For a line and a point not on the line, there is exactly one line parallel to this line through the point. There are infinitely many lines that pass through A, but only one is parallel to l.
-1.331. -1.1 * -1.1 * -1.1
This one isn’t really that hard. the answer is 24.
Answer:
For 99% of confidence interval is 67.5±1.3524
Step-by-step explanation:
Given:
Mean height =67.5 inches
Standard deviation:2.1 inches
Z at 99%.
No of samples 16.
To find:
confidence interval
Solution:
We have formula for confidence interval,
=mean ±Z*{standard deviation/sqrt(no.of observation)}
Now
Z=99%
has standard value as ,
Z=2.576
Confidence interval= mean±Z{standard deviation/sqrt(No. of samples)}
=67.5±2.57{(2.1/sqrt(16)}
=67.5±2.576(2.1/4)
=67.5±1.3524
Answer:
yes it's rotated 180 degree angle
