Answer:
D) y = − 3/2 x + 3 /2
Step-by-step explanation:
3x+2y =1
We need to get this in slope intercept form (solve for y)
Subtract 3x from each side
3x-3x +2y = -3x+1
2y = -3x+1
Divide by 2
2y/2 = -3/2x+1/2
The slope is -3/2
We want a line that is parallel so the slope is the same
m = -3/2
We an use point slope form since we have the slope and a point
y - y1 = m(x-x2)
y - 0 = -3/2(x-1)
Distribute
y = -3/2x +3/2
Answer:
The easiest way to do this is to reflect Figure I over the Y axis. Then move it up 3 and left 2.

150 divided by 25 is 6 so the answer is 6
Answer:
a) 0.857
b) 0.571
c) 1
Step-by-step explanation:
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 possibility 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; So 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.
