Answer:

True.

Step-by-step explanation:

37°45' + 142°15'

= (37 + 142)° + (45 + 15)'

= 179° + 60'

= 179° + 1°

= 180°

there being 60 minutes of arc in one degree of arc.

Consider the triangle.<br> 45°<br> 80°<br> Find the measure of the unknown third angle.

Elina [12.6K]

Answer:

$55 \degree$

Step-by-step explanation:

Let the unknown angle be x

As the interior angles in a triangle are added up to 180°

$x + 45 + 80 = 180 \\ x + 125 = 180 \\ x = 180 - 125 \\ x = 55 \degree$

Hope this helps you.

What happens to the interval as the level of confidence is changed? Explain why this is a logical result.

Elan Coil [88]

Answer with explanation:

A x% confidence interval interprets the percentage of certainty that a person can believe that the true population parameter.

It is also represented as Point estimate ± Margin of error

Confidence level is proportional to the Margin of error.

As confidence level increases the error bound increases that makes the confidence interval broader.
As confidence level decreases the error bound decreases , making the confidence interval narrower.
