Answer:
0.58
Step-by-step explanation:
The probability that Taymoor gets at least one job is a sum of probabilities of 3 events:
1.He gets Job 1 (P(1.yes)= 0.3) and doesn't get the job 2 (P(2.not)=1-0.4=0.6)
P(1.yes,2.not)=P(1.yes)*P(2.not)=0.3*0.6=0.18
2. He doesn't get job1 (P(1.not)= 1-03=0.7 ) and gets job2(P2.yes)=0.4)
P(1.not,2.yes)=P(1.not)*P(2.yes)=0.7*0.4=0.28
3. He gets job1 (P(1.yes)= 0.3 ) and gets job2(P2.yes)=0.4)
P(1.yes,2.yes)=P(1.yes)*P(2.yes)=0.3*0.4=0.12
The resulted probability is P(gets job)= 0.18+0.28+0.12=0.58
X^2+4x+4=8
-8 -8
subtract 8 from both sides
x^2+4x-4=0
now factor using quadratic formula
ax^2+bx+c=0
x= -b +-[ (sqrt (b^2-4ac))/2a ]
x=-2(1+sqrt(2))
x= 2(sqrt(2) -1)
hope that helps, hopefully you know how to plug and chug into quadratic formula. if not you can ask for help
A) 12 m/s/3 seconds, 4 m/s/1s = 4 m/s^2
b) -12 m/s in 4 seconds = -3 m/s^2
c) 18+7*12=102 meters

Answer:
no
Step-by-step explanation:
The graph of this equation on an x-y plane is a vertical line. The input value x=15 maps to an infinite number of outputs (y-values). For a relation to be a function, each input can only map to one output.
x = 15 is not a function
Answer:
A parallel y = 3x-1
B perpendicular y = -1/3x+9
Step-by-step explanation:
y = 3x-4 is written in slope intercept form (y=mx+b) so the slope is 3.
A. If the lines are parallel they have the same slope
m parallel is 3
Using point slope form
y-y1 = m(x-x1)
y-8 = 3(x-3)
Distribute
y-8 = 3x-9
Add 8 to each side
y-8+8 = 3x-9+8
y = 3x-1
This is slope intercept form
B If we want perpendicular lines, the slope is the negative reciprocal
m perpendicular is -(1/3) = -1/3
Using point slope form
y-y1 = m(x-x1)
y-8 = -1/3(x-3)
Distribute
y-8 = -1/3x+1
Add 8 to each side
y-8+8 = -1/3x+1+8
y = -1/3x+9
This is slope intercept form
