The scatter plot shows the systolic blood pressure of people of several different ages. the equation represents the linear model for this data. y = x + 95 according to the model, how much does the systolic blood pressure increase for each year of age? 1 mm hg per year 5 mm hg per year 15 mm hg per year 95 mm hg per year 110 mm hg per year a graph measuring systolic blood pressure in relation to age. a line indicates that blood pressure increases as age increases plz answer 1 mm hg per year

Asmall (but heavy) particle placed in a glass of water will follow a zigzag motion because the particle will bounce off of the water molecules it meets. this is called brownian motion. a physicist simulates this on a computer, by varying the distance a particle can travel (called the mean free length), on average, before it collides with a water molecule and assigning the change in motion to be one of 8 directions, each with a similar probability. by running the simulated particle (with the same mean free length) many times she determines that it should take 15 seconds, on average, for the particle to fall to the bottom, with a standard deviation of 1.5 seconds. next she lets a real particle fall through a glass of water and finds that it took 18 seconds. what does she conclude, and why?

If f(x) = x+8 and g(x) = 4x- 3, find (f+g)(x)
