What needs to be done first is to add up females and males that have passed.
42 + 14 = 56
so out of 56 students who passed 42 females passed 42/56 = 3/4 = 0.75
out of 56 students who passed, 14 males passed which turns into 14/56 = 1/4 = 0.25
check work; 0.75 + 0.25 = 1.00
NOW WE ARE DOING FAILS.
15 + 5 = 20
so out of 20 students who failed, 15 females failed so it turns into 15/20 = 3/4 = 0.75
out of 20 students who failed, 5 males failed. 5/20 = 1/4 = 0.25
check work; 0.75 + 0.25 = 1.00
i hope this helped! :)
Answer:
10
Step-by-step explanation:
Seeing the 5 12 13 triple you get 1/2x=5 so
x=10
If the probability of spinning an A once is 1/12, then the probability of spinning an A 3 times is 3 × 1/12.
3 × 1/12 = 3/36
Simplify
3/36 = 1/12
Answer:
29
Step-by-step explanation:
Assume the number as x
2x - 9 = 49
2x = 58
x = 29
Answer:
There are no real roots for this equation.
Step-by-step explanation:
The only solution is irrational: x-√(4-8x)=0
I have provided a graph to help you with this problem.
