Answer:
0.6667 = 66.67%
Step-by-step explanation:
If each number cube has 6 numbers, the two cubes have a total of 6 * 6 = 36 results.
To have equal numbers in each cube, the cases are:
(1,1), (2,2), (3,3), (4,4), (5,5), (6,6) -> 6 cases
To have a odd sum, the cases are:
(1,2), (1,4), (1,6),
(2,1), (2,3), (2,5),
(3,2), (3,4), (3,6),
(4,1), (4,3), (4,5),
(5,2), (5,4), (5,6),
(6,1), (6,3), (6,5). -> 18 cases
So we have a total of 18 + 6 = 24 cases, then the probability is:
P = 24 / 36 = 0.6667 = 66.67%
Student B:
1/2 / 4
= 1/2 x 1/4
= 1/8
student A:
2/3 / 6
= 2/3 x 1/6
= 1/9
student C:
4/5/ 8
= 4/5 x 1/8
= 1/10
answer
student B: 1/8 of a mile per minute
student A: 1/9 of a mile per minute
student C: 1/10 of a mile per minute
Put numbers in order: 4,5,6,6,7,8,9,9,10,10,12,12,14,15
Cut the list into two equal parts: 4,5,6,6,7,8,9 and 9,10,10,12,12,14,15
Find middle numbers: 4,5,6,6,7,8,9 and 9,10,10,12,12,14,15
Lower quartile: 6
Upper quartile: 12
The difference of the values of the first and third quartiles of the data set is 12 - 6 = 6
The amount spent on each tube is $18.5
The total amount spent to rent 15 tubes by the group is $277.50.
Since they did not specify in the question the types of tubes they rented, we cannot determine each types of tubes that the group rented but we can determine the amount spent on each tube provided that they are all the same types.
∴
if 15 tubes = $277.50
1 tube = $x
By cross multiplying:
Therefore, we can conclude that the amount spent on each tube is $18.5

Answer:
x > 4/33
Step-by-step explanation:
(-4 +8x) +3> x/-4
8x - 1 > x/-4
-32x + 4 < x
4 < 33x
4/33 < x
