The mean is the average, so add all the numbers and divide by 7 (7 terms).

-14 is the sum, divided by 7 = -2

The mean is -2.

Mrac [35]

Answer:

\frac{\pi}{3} radians

Step-by-step explanation:

Number of hours on a clock = 12

Since, measure of a circle at the center = 360°

Measure of central angle formed by the arc between each number (representing hours) = \frac{360}{12}

                                  = 30°

Central angle formed by the arc intercepted by the hands of the clock at 8:00 = 4 × 30°

        = 120°

Therefore, angle measure in radians = \frac{\pi }{360}\times (120^0)

                                                              = \frac{\pi }{3}

Angle formed by the hands of the clock at 8:00 = \frac{\pi}{3} radians

Y=5x+2 <br> 4x-y=0<br> is (2,12) a solution of the system?
Svetach [21]

Answer:

The point (2,12) is not a solution of the system

see the explanation

Step-by-step explanation:

we have

y=5x+2 ----> equation A

4x-y=0 ----> equation B

Solve the system by elimination

Adds equation A and equation B

y=5x+2\\4x-y=0\\------\\y+4x-y=5x+2+0\\4x=5x+2\\5x-4x=-2\\x=-2

Find the value of y

substitute the value of x in the equation A

y=5(-2)+2=-8

The solution of the system is the point (-2,-8)

The system has only one solution, because the intersection point both lines is only one point

therefore

The point (2,12) is not a solution of the system
