Answer:
B
Step-by-step explanation:
Total number of marbles in the bag =20
Number of blue marbles =4
Now we just want two blue marbles out of four.
Probability of taking out first marble which is blue =4/20
Now after we took out one blue marble , number of blue marbles left are 3.
Probability of taking out second marble which is blue =3/20
Total probability = 4/20 *3/20 = 12/400
So probability of taking out two blue marbles is 0.03 or 12/400.
5x - 3y = -11 (×2)
2x - 6y = -14 (x5)
10x - 6y = -22
10x - 30y = -70
---------------------- -
24y = 48
y = 2
Answer:
The expression that converts 8 radians to degree is: degrees = (8 rad)*180/pi
Step-by-step explanation:
To convert any number from radians to degrees we must use the equation below:
degrees = radians*180/pi
Therefore to convert 8 radians to degree we need to apply this value to the formula above:
degrees = 8*180/pi
degrees = 1440/pi
degrees = 458.366º
The expression that converts 8 radians to degree is: degrees = (8 rad)*180/pi
