P of selecting point on the shaded region = shaded area/whole area
<span>P( selecting point on the shaded ) = ( the four shaded circles ) / the whole square </span>
<span>P of selecting point on the shaded = ( 4 * ( π * r^2 ) )/ x^2 </span>
<span>P of selecting point on the shaded = ( 4 * ( π * (x/4)^2 ) )/ x^2 </span>
<span>P of selecting point on the shaded = ( 4 * ( π * x^2/16 ) )/ x^2 </span>
<span>P of selecting point on the shaded = ( π * x^2/4 )/ x^2 </span>
<span>P of selecting point on the shaded = x^2( π/4 )/ x^2 </span>
<span>P( selecting point on the shaded ) = π/4 ≈ 0.7854 ≈ 79%
=80%
D is right option hope this helps</span>
Answer:
165 centimeters
Step-by-step explanation:
A pentagon has 5 sides
Each side is 33 centimeters long
5 x 33 = 165
Answer:8^1/6*2^x=32^1/2
We move all terms to the left:
8^1/6*2^x-(32^1/2)=0
Domain of the equation: 6*2^x!=0
x!=0/1
x!=0
x∈R
We get rid of parentheses
8^1/6*2^x-32^1/2=0
We calculate fractions
There is no solution for this equation
Answer:
40
Step-by-step explanation:
-3 2
-15 - 2 = -17
1 5
-1 - 25 = -26
5<em> </em> -1
-25 - (-1) = - 24
1 <em> -5</em>
2 - <em>15</em> = -13
<em>-3</em> 2
area = |-17 - 26 - 24 - 13|/2 = |-80|/2 = 80/2 = 40
Answer: 40
Answer:
Option D.
Step-by-step explanation:
Total number of cards = 52
Total number of cards of each suit (♠, ♣,♦, and ♥) = 13
The probability of getting a card of heart is
The probability of getting a card other then heart is
If Ming randomly draw a card from the deck 300 times, putting the card back in the deck after each draw, then the number of cards she will draw something other than a heart is
Close to 225 times but probably not exactly 225 times.
Therefore, the correct option is D.
