If x=7, determine which lines must be parallel?

Mathematics
1 answer:
vlada-n [284]3 years ago
4 0

Answer: All the lines which are parallel to Y-axis including Y-axis must be parallel to the line x=7.


Explanation:

                    We can understand it by drawing the line x=7 on the graph.

In the graph, it has shown that x=7 is parallel to Y-axis.

And if we talk about a set of lines x=n, where n is a real number then these lines are parallel to y-axis.

since,  we know that if one line is parallel to another line and that line is also parallel to a third line then these three lines must be parallel.

so we can say that, All lines which are parallel to y-axis as well as y-axis are parallel to x=7.

In order to estimate the average electric usage per month, a sample of 81 houses was selected and the electric usage was determi
lana [24]

Answer:

Confidence interval:  (1760,1956)

Step-by-step explanation:

We are given the following information in the question:

Sample size, n = 81

Sample mean =

\bar{x} = 1858 \text{ kWh}

Population standard deviation =

\sigma = 450 \text{ kilowatt-hours}

Confidence Level = 95%

Significance level = 5% = 0.05

Confidence interval:

\bar{x} \pm z_{critical}\displaystyle\frac{\sigma}{\sqrt{n}}

Putting the values, we get,

z_{critical}\text{ at}~\alpha_{0.05} = \pm 1.96

1858 \pm 1.96(\displaystyle\frac{450}{\sqrt{81}} ) = 1858 \pm 98 = (1760,1956)
