Answer:
B. y = -x - 1
Step-by-step explanation:
Perpendicular lines have opposite reciprocal slopes, so the slope of the new line will be -1.
Plug the slope and the given point into y = mx + b to find b:
y = mx + b
3 = -1(-4) + b
3 = 4 + b
-1 = b
Then, plug this and the slope into y = mx + b
y = -x - 1
So, the correct answer is B, y = -x - 1

Answer: 16 rotations
Step-by-step explanation:
Given : Shawn is coasting down a 500 cm long ramp on his inline skates. The wheels on his inline skates are 32 cm in circumference.
Length of ramp = 500 cm
Circumference of wheels = 32 cm
Formula :
Number of rotations = Length of ramp divided by Circumference of wheels
= 500 cm ÷ 32 cm
= 15.625 ≈ 16 [approx]
Therefore, each wheel makes 16 rotations while Shawn is coasting down the ramp.
Answer:
0.382
0.4
option (a)
Step-by-step explanation:
Formula to calculate probability
a)
probability = number of times event occur / total number of trials
Experimental probability of landing on white = 191/500 = 0.382
b)
probability = favourable outcome / total outcome
Theoretical probability of landing on white = 2/5 = 0.4
c)
As more trials are conducted, the experimental probability generally gets closer to the theoretical probability.
