A square pyramid is made up of a base with a side length of 10 inches and faces that are triangles with a height of 12 inches. W
Ganezh [65]

Answer:

D. 340 square inches

Step-by-step explanation:

Side length translates to 1 side of the square, so you do 10 x 10 to find the area of the square.

10 x 10 = 100

The triangle one isn't much more difficult. The formula for finding the area of a triangle is bh1/2

So:

10 x 12 = 120/2=60

From there just multiply the result by 4- the amount of triangles on the square pyramid, and you'll get your answer.

60

x 4

240 + 100 = 340 square inches

The statement "Yes, all the conditions for Inference have been met" is correct.

<h3>What is a t-test?</h3>

A t-test is a hypothesis-testing technique for analyzing the means of one or two populations. A t-test can be used to see if a single group differs from a known value, if two groups differ from each other (an independent two-sample t-test), or if paired measurements show a significant difference.

We have:

Null hypothesis:H0: μ1 – μ2 = 0,

Alternative hypothesis: Ha: μ1 – μ2 < 0

As it is mentioned that the samples are drawn randomly and mentioned that no skewness is observed, this Indicates that the distribution is approximately normal

The total number of readings = 10

Which is not more than 10% of the Population size.

Thus, the statement "Yes, all the conditions for Inference have been met" is correct.
