Answer:
K(A+B)/A
Step-by-step explanation:
K = (AB)/(A+B)
K(A+B)=AB
K(A+B)/A=B
The correct answer should be 7 levels for the entirety of the week. However, there are two solutions that satisfy this question so perhaps it is really asking how many additional levels he is able to beat. In this case, the answer should be B: x > 5 2/3
Answer: 14/285
Step-by-step explanation:
B = 10
G = 8
T = 18
So its a 8/20 that 1 is a girl but then 2nd its 7/19 and 3rd 6/18 so
8/20 * 7/19 * 6/18 = 14/285
1) is the first answer and 2) is the last answer
Less than 3 is about 10.75% and greater than 13 is about 6.18%.
To find these percents, you need to find the z-score for each value. Then, use your table to find the correct percent. Be sure to find the side above 13 when you use your chart.
For less than 3:
(3 - 7.45) / 3.6 = -1.24 = The percent below this is 0.1075
For greater than 13:
(13 - 7.45) / 3.6 = 1.54 = The percent above this is 0.0618
