Answer:

Step-by-step explanation:

area formula is

πr^{2}

plug in values:

9π

which equals

28.2743339

or you can write 9π im not sure what your teacher prefers

circumference formula is

2πr

which equals

6π

or

18.8495559

For an outdoor concert by the city​ orchestra, concert organizers estimate that 16 comma 000 people will attend if it is not rai
Sladkaya [172]

Answer:  13300

========================================

Work Shown:

A = event that it rains

B = event that it does not rain

P(A) = 0.30

P(B) = 1-P(A) = 1-0.30 = 0.70

Multiply the attendance figures with their corresponding probabilities

  • if it rains, then 7000*P(A) = 7000*0.30 = 2100
  • if it doesn't rain, then 16000*P(B) = 16000*0.70 = 11200

Add up the results: 2100+11200 = 13300

This is the expected value. This is basically the average based on the probabilities. The average is more tilted toward the higher end of the spectrum (closer to 16000 than it is to 7000) because there is a higher chance that it does not rain.

Find the measure of angle 1<br><br> 60 degrees<br> 72 degrees<br> 36 degrees<br> 54 degrees
GarryVolchara [31]
The sum of all angles (around the black dot) is 360°

All 5 angles (if you forget the red line) are the same; so each angle is 360°/5 = 72°

So Angle 1 is 72°

PLEASE HELP
rodikova [14]

Answer:  B. 1/2(y - 116) = 64    

Step-by-step explanation:

Since, we know that,

The angle formed by two tangent = \frac{1}{2}(\text{Difference of intercepted Arcs} )  

= \frac{\text{major arc - minor arc}}{2}

Here, Major arc = y°

Minor arc = 116°

And, Angle made by two tangents YX and YZ,

m\angle XYZ = \frac{\text{y - 116}}{2}

64 = \frac{\text{y - 116}}{2}  ( because,  m\angle XYZ = 64^{\circ} )

⇒ \frac{\text{y - 116}}{2} = 64

Which is the required equation to find y,  the measure of XWZ.

Thus, Option B is correct.
