93.9 or 17702.3 I think it’s the long 1 tho
Answer:
a) 0.857
b) 0.571
c) 1
Step-by-step explanation:
Based on the data given, we have
- 18 juniors
- 10 seniors
- 6 female seniors
- 10-6 = 4 male seniors
- 12 junior males
- 18-12 = 6 junior female
- 6+6 = 12 female
- 4+12 = 16 male
- A total of 28 students
The probability of each union of events is obtained by summing the probabilities of the separated events and substracting the intersection. I will abbreviate female by F, junior by J, male by M, senior by S. We have
- P(J U F) = P(J) + P(F) - P(JF) = 18/28+12/28-6/28 = 24/28 = 0.857
- P(S U F) = P(S) + P(F) - P(SF) = 10/28 + 12/28 - 6/28 = 16/28 = 0.571
- P(J U S) = P(J) + P(S) - P(JS) = 18/28 + 10/28 - 0 = 1
Note that a student cant be Junior and Senior at the same time, so the probability of the combined event is 0. The probability of the union is 1 because every student is either Junior or Senior.
MY answer is #4 4.3 Times 107
Answer: -7, 8
Step-by-step explanation:
It is
The equation of the perpendicular line is 13y=27-x
Step-by-step explanation:
Writing the given equation to slope-intercept form.
y=− 1 3 x+6
The slope of this line is 13
The perpendicular slope is -1/13
Using the new slope and the given point into the slope-intercept form to find the y-intercept.
4=-1/13(2)+c
2=-1/13+c
c=27/13
y=-1/13x+27/13
So the equation of the perpendicular line is 13y=27-x
