we have

Min=26

Q1=67

Q2=80

Q3=87

Max=100

Mean=76

Mode=100

standard deviation=76

IQR=20

so

In this problem

the mean is equal to the standard deviation

therefore

<h2>The standard deviation is incorrectly</h2>

What is the measure of the arc from A to B that does not pass through C?
sergeinik [125]

Applying the inscribed angle theorem, the measure of the arc from A to B is: 100 degrees.

<h3>What is the Inscribed Angle Theorem?</h3>

The inscribed angle theorem states that an inscribed angle in a circle is half the central angle.

Angle BAC = 40 degrees, so, central angle = 80 degrees. Arc BC would also be 80 degrees.

Measure of arc AC through point B = 180 degrees.

Arc AB = 180 - 80 = 100 degrees.
