Which is an equation of the line with slope 1/2 that contains (–4, 7)? a. y – 7 = (x – 4)
y – 7 = 1/2 ( x – 4),

b. y – 7 = (x + 4)
y – 7 = 1/2 ( x + 4),

c. y – 7 = 1/2 –4x +
y – 7 = –4 x + 1/2

d. y + 7 = (x + 4)

2x + 1 < 5 solve the following inequality. then place the correct number in the box provided.

Arestaurant gives out a scratch-off card to every customer. the probability that a customer will win a prize from a scratch-off card is 25%. design and conduct a simulation using random numbers to find the experimental probability that a customer will need more than 3 cards in order to win a prize. justify the model for your simulation, and conduct at least 10 trials.
