Process average or mean: is computed by dividing the total of the measurements made on the process by the number of measurements

Orlov [11]

Process average or mean is computed by dividing the total of the measurements made on the process by the number of measurements used to compute the total approximates. For example a coach wants to know if football players who warm up before a game will score more points than those who don't warm up. He will break the team up into two groups and make sure each player gets equal time on the field. He will then count how many points each player makes during the game. After counting them, add the scores of the group that he divided and then divided it by the number of player in that group to get an average score on teams that warm up or do not warm up before the game.

20 POINTS AND A FOLLOW plus BRAINIEST IF RIGHT 1. What is the area of sector GHJ, given that 0=pi/4 radians ? Express your answe

Llana [10]

1. To solve this we are going to use the formula for the area of a sector of a circle: $A= \frac{1}{2} r^2 \alpha$
where
$A$ is the area of the sector
$r$ is the radius of the circle
$\alpha$ is the angle in radians

We know from our problem that the radius of the circle is 5 cm and the angle of the sector is $\frac{ \pi }{4}$ , so $r=$ and $\alpha = \frac{ \pi }{4}$ . Lets replace those values in our formula:
$A= \frac{1}{2} r^2 \alpha$
$A= \frac{1}{2} (5)^2( \frac{ \pi }{4} )$
$A= \frac{25 \pi }{8}$
$A=9.8$

We can conclude that the area of sector GHJ in terms of pi is $\frac{25 \pi }{8}$ $cm^2$ , and as a decimal rounded to the nearest tenth is 9.8 $cm^2$ .

2. To c<span>onstruct the circle that circumscribes triangle DEF, we are going to draw the perpendicular bisectors of triangle DEF, and then we are going to draw the circle with radius at the interception point of the bisectors. Remember that the perpendicular bisector are the lines that passes trough the midpoint of the segment and are perpendicular to the segment.</span>
