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.
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.
24.6(x+5)=6x+30
25.-8(y-1)=-8y+8
26.-3(-5z+12)=15z-36
27.1/3(6z+10)=2z+10/3

We first calculate the z-score corresponding to x = 1075 kWh. Given the mean of 1050 kWh, SD of 218 kWh, and sample size of n = 50, the formula for z is:
z = (x - mean) / (SD/sqrt(n)) = (1075 - 1050) / (218/sqrt(50)) = 0.81
From a z-table, the probability that z > 0.81 is 0.2090. Therefore, the probability that the mean of the 50 households is > 1075 kWh is 0.2090.
