Answer:
d
Step-by-step explanation:
On a number line that represents an inequality, if it has a closed circle the inequality will say or show a greater/ less than or equal to or it will say the number is at least this. The at least means that it could be more than this but it could also be this number.
2 - 3/2(x) greater than or equal to 5 1/2 - This one is the last option
(2 * x) + (-2) greater than or equal to 8 - This one is the first option
7 - (4 * x) greater than 13 - The second one
4 + (3 * x) less than 19 - The third one
Answer: 7/26
Step-by-step explanation:
Number of purple marbles = 6
Number of white marbles = 7
Total number of marbles = 13
The probability of first drawing a white marble will be = 7/13
The probability of drawing a purple marble the second time will be = 6/12 = 1/2
The probability that the first marble is white and the second one is purple will now be:
= 7/13 × 1/2
= 7/26
Note that since there are 13 marbles, when the first purple marble is drawn, there'll be 12 marbles left.
