A pair of intersecting planes and where they intersect
1 answer:
Answer:
Two planes always would intersect at a line, as shown in attached figure below.
Step-by-step explanation:
As we know that
A plane has basically 2 dimensions.
- length and
- width
But as the plane is infinitely large, we can say that length and width of a plane is not supposed to be measured. (can not be measured)
Let suppose we have a pair of intersecting planes.
If If two intersecting planes are not parallel, then they would intersect each other somewhere.
BUT
Two planes always would intersect at a line, as shown in attached figure below.

X[bar]= 115
Step-by-step explanation:
Hello!
Every Confidence interval to estimate the population mean are constructed following the structure:
"Estimator" ± margin of error"
Wich means that the intervals are centered around the sample mean. To know the value of the sample mean you have to make the following calculation:
= 115
Since both intervals were calculated with the information of the same sample, you can choose either to calculate the sample mean.
