1. The scatter plot shows the weights y of an infant
from birth through x months.
a. At what age did the infant weigh 11 pounds?
b. What was the infant's weight at birth?
c. Draw a line that you think best approximates the points
d. Write an equation for your line.
e. Use the equation to predict the weight of the
infant at 18 months.
f. Does the data show a positive, a negative, or no relationship?

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
