-4 ×2 =8
34 -(-4)2
34 + 8 (minus minus becomes +)
42
We want to get b alone so I would start by multiplying 2 to get it on the other side of the = sign. So then I have 2L=a-b. I would subtract a on both sides and then I would have 2L-a= -b. We don't want a -b so I would multiply everything by -1 so then the answer would then be a positive b= -2L+a
The slope of this line is 5/3 so a perpendicular slope would be opposite reciprocal to this or -3/5
Answer:
9/35
Both
Step-by-step explanation:
Number of girls = 9
Number of boys = 6
In other to choose two representatives, the probability of choosing a boy and then a girl is ;
Total number of boys and girls = (9 +6) = 15
Probability = (required outcome / Total possible outcomes)
Probability of a girl and then a boy :
(Number of girls / total number) × (number of boys / total number - 1)
(9/15) × (6/14) = 54/210 = 9/35
B.) The event is both dependent and independent because both events can occur independently, however, the total number of possible outcomes is altered when determining the probability for the second spot.
