Answer:
im pretty sure the answer is eight!
Step-by-step explanation:
Step-by-step explanation:
Two lines that are perpendicular to each other has -1 as the product of thir gradient.
Since the gradient of the line y = 3 - x is -1, the gradient of the other line must be 1.
So y = x + c.
When x = 7, y = 1. 1 = 7 + c, c = -6.
Hence the equation of the line is y = x - 6.
Probability? I'm guessing it is asking for a written response so I'll try my best.
If the coin landed heads up 16 times then the probability would be 16/40 which can be reduced to 2/5
If the coin landed tails up 24 times you would do the same so 24/40 and then you can reduce that to 3/5
Part a: The experimental probability of it being tails would be 3/5
Part b: The experimental probability of it being heads would be 2/5
hopefully, I understood the question correctly but I believe this is the right answer
