(a) z=-3.49 What the answer to this

Mathematics
1 answer:
MariettaO [177]4 years ago
5 0

Answer:

Step-by-step explanation:

Depends upon what you're looking for!  If you want the area under the standard normal curve to the left of z = -3.49, here's one way to do it on a TI 83 calculator:

normcdf(-100, -3.49).  Because the z-value -3.49 is more than 3 standard deviations below the mean, the area to the left of z = -3.49 resembles 0.002.  Try this on your calculator:  normcdf(-100, -3.49)

The problem gives us points (4, 12) and (11,26). We first find the slope using m=(y2-y1)/(x2-x1). We substitute and get m=(26-12)/(11-4). This simplifies to m = 2. We can then use the point-slope form y-y1 = m(x-x1). We substitute and get y - 12 = 2(x - 4). We distribute: y - 12 = 2x - 8. We add 12 to both sides to get our final answer, y = 2x + 4.
