Step-by-step explanation:
Please find the attachment.
We have been given that a container is shaped like a triangle prism. Each base of container is an equilateral triangle with each side 6 cm. The height of container is 15 cm.
To find the lateral surface area of our given container we will use lateral surface area formula of triangular prism.
, where, a, b and c represent base sides of prism and h represents height of the prism.
Upon substituting our given values in above formula we will get,
Therefore, lateral surface area of our given container is 270 square cm.

Answer: A. 10% of the time, the population parameter will lie outside of the interval.
Step-by-step explanation:
If we have confidence interval is that we are certain that it contains the true population parameter in it.
Similarly , if we have a 90% confidence interval for a population parameter, then we are 90% certain that it contains the true population parameter in it.
i.e. 10% not certain that it contains the true population parameter in it.
i.e. 10% of the time, the population parameter will lie outside of the interval.

Step-by-step explanation:
2x - y > 4 ⇒ y < 2x - 4
x + y < - 1 ⇒ y < - x - 1
