Answer:
The probability of drawing a blue marble is the same as drawing either a red or a green marble. and the probability of not drawing a blue marble is 50%.
Step-by-step explanation:
| 5x - 6 | = -41....no solution because an absolute value cannot be negative
|7x + 13 | = 27
7x + 13 = 27 -(7x + 13) = 27
7x = 27 - 13 -7x - 13 = 27
7x = 14 -7x = 27 + 13
x = 14/7 -7x = 40
x = 2 x = -40/7
so basically, equation 1 has no solution and equation 2 has 2 solutions
Answer:
The mode = 24
Probability = 0.14
Probability = 0.74
Step-by-step explanation:
Mode is 24 because it has the highest frequency.
The probability of winning a score of 25 = 7/50 = 0.14 = 14%
Probability of winning sore of 23+ = 37/50 = 74% = 0.74
Hope this helps.
Good luck
