Creo que con 15
Step-by-step explanation:
50 -------> 100%
X ---------> 30%
X = (50*30)/100
X= 15 boys
Answer:
55.5%
Step-by-step explanation:
It may be useful for you to remember the formula ...
p(A or B) = p(A) + p(B) - p(A and B)
Using the given scenario, we can find ...
p(C or M) = p(C) + p(M) - p(C and M)
= 35.1% + 37.7% - 17.3% = 55.5% . . . . p(passing at least one course)
Answer:
Step-by-step explanation:
If you are always included to lead, that leaves 10 students to choose from.
If all that is important is being selected, then there are 10C3 = 120 ways to choose them.
If each selection has a unique duty, then there are 10P3 = 720 ways to assign them their jobs.
Slope intercept form of a line:
y=mx +b
Therefore:
9x-7y=-7
-7y=-9x-7
y=-9/-7 x - 7/-7
y=9/7 x + 1
Answer: the slope intercept form would be: y=9/7 x + 1
