Answer:

slope=2 ie m=2

y=2x+b

and to solve b, we put in 4 and 9 into the equation

9=2*4+b, so b=9-8=1

hence y=2x+1

What is the equation of a line that has slope = -4 and y-intercept is (0, 3)?
PolarNik [594]

Answer: y = -4x + 3

Step-by-step explanation:

y = mx + b

=> y = -4x + b

Find "B":

y = -4x + b

=> 3 = -4(0) + b

=> b = 3

so y = -4x + 3

1) The probability of drawing a pink chip from a bowl of different-colored chips is 0.35, theprobability of drawing a blue chip
docker41 [41]

Answer:

1) 0.5 or 50%.

2) Order does not matter: 3,003 combinations.

   Order matters: 360,360 permutations.

Step-by-step explanation:

1) The probability of drawing either a purple or a blue chip is the sum of both individual probabilities:

P(B\ or\ P) = P(B) +P(P) = 0.46+0.04\\P(B\ or\ P) = 0.50

the probability that a blue or a purple chip will be drawn is 0.5 or 50%.

2)

a) Choose 5 items from a  total of 15 items when order does not matter:

C(15,5) = \frac{15!}{(15-5)!5!}=\frac{15*14*13*12*11}{5*4*3*2*1}\\C(15,5) = 3,003

b) Choose 5 items from a  total of 15 items when order matters:

P(15,5) = \frac{15!}{(15-5)!}=15*14*13*12*11}\\P(15,5) = 360,360
