If the length of an arc is 12 inches and the radius of the circle is 10 inches, what is the measure of the arc?I don't get this, keep getting it wrong. Can someone lead me through it???? PLZ

Answers

Assuming you are working in radians, the length of a circular arc is given by the definition of te radian:

$s =r\theta$ which can be re-arranged to $\theta = (s)/(r)$

Using supplied known values:
$\theta = (12)/(10) = 1.2 radians$

. (Round off your answer to the nearest tenth.)

Answers

Answer

593.3

Explanation

Mean is also called average. It represents the average mark of a given data.

For the question above, you to add all the marks of the students then you divide by the number of students.

Mean = (650+550+380+720+710+ 550)÷6

= 3,560 ÷ 6

=593.3333

Answer to the nearest tenth = 593.3

The point estimate of the meanscore for the students is 593.34 if the number of observation is 6.

What is mean?

It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.

We know,

Mean = (sum of observation)/(number of observation)

Sum of scores = 650+550+380+720+710+550 = 3560

Number of observation = 6

Mean = 3560/6 = 593.33 = 593.34

Thus, the point estimate of the meanscore for the students is 593.34 if the number of observation is 6.
