Answer:

∠1=55°

Step-by-step explanation:

Since all the angles in a triangle have to add up to 180° we can make an equation

80°+45°+∠1=180°

∠1=55°

A random sample of 10 subjects have weights with a standard deviation of 11.0995 kg. What is the variance of their weights?

goblinko [34]

Answer:

$123.19890025 kg^2$

Step-by-step explanation:

We are given that

Standard deviation, s=11.0995 kg

Sample size, n=10

We have to find the variance of their weights.

We know that

Variance= $(standard\;deviation)^2$

Using the formula

The variance of their weights

= $(11.0995)^2$

= $123.19890025 kg^2$

Hence, the variance of their weights= $123.19890025 kg^2$
