Given



Required

First, we calculate the z score

So, we have:




So:

From z score probability, we have:

Answer: 50w+150>650

Answer:
Step-by-step explanation:
Subtract 4 by 2.5 which is 1.5
Divide 4 by 2.5 which is 1.6
Im not sure if you have to divide or subtract so...
Slope = (9-7)/(6-3) = 2/3
equation
y - 7 = 2/3(x - 3)
y - 7 = 2/3 x - 2
y = 2/3 x + 5
answer
equation
y = 2/3 x + 5
