A) A straight line.
This is so because the equation is of the first degree (the largest power of x is one). Thus making it a linear equation. The gradient in the equation here (3/4) shows that when you increase the value of x by 1, they value for y increases by 3/4. Since the increments are constant, you will see that the function is a straight line if you draw it.
The quantity you want is the area under the standard normal curve (with mean 100 and std dev 15) between 110 and 120.
According to my TI-83 calculator,
normalcdf(110,120, 100, 15) = 0.16, or 16%.
Subtract 4 from both sides.
2a+4>12
2a>8
Divide by 2.
a>4
I hope this helps!
