Answer:

Step-by-step explanation:

It's an obtuse. A triangle is considered acute if all 3 angles are acute; it is considered obtuse if one of its angles is obtuse. Ours has a 100 degree angle, so it is obtuse.

Answer:

The mean of of the sample mean of these quality checks is 10 and the standard deviation is 0.7155.

Step-by-step explanation:

To solve this question, we use the central limit theorem.

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$

In this problem, we have that:

$\mu = 10, \sigma = 1.6, n = 5, s = \frac{1.6}{\sqrt{5}} = 0.7155$

The mean of of the sample mean of these quality checks is 10 and the standard deviation is 0.7155.
