Answer:
The answer is - 60
Step-by-step explanation:
Answer:
120
Step-by-step explanation:
Blue marbles = 2
Red marbles = 3
Total marbles = 2 + 3 = 5
If a marble is drawn 300 times ;prediction for the number of times a blue marble will be drawn :
P(drawing a blue marble) = number of blue marbles / total number of marbles
= 2 /5 = 0.4
Predicted number of times blue is drawn in 300 selections :
300 * 0.4 = 120
Approximately 120 times
To find the percent, we first find the decimal.
To do that we divide 5 / 6, which gives us approximately 0.83333, now we multiply it by 100 since percentages are parts of 100.
0.83333 * 100 = 83.33%
Answer:
x=2
Step-by-step explanation:
-3*(x-2)-(2*x-3)-(5-(4*x-2))=0
((0 - 3 • (x - 2)) - (2x - 3)) - (7 - 4x) = 0
2 - x = 0
-x+2 = 0
Subtract 2 from both sides of the equation :
-x = -2
Multiply both sides of the equation by (-1) : x = 2
