( I'll give you 30 points )

The life spans of a computer manufacturer’s hard drives are normally distributed, with a mean of 3.5 years and a standard deviation of 0.75 years. What is the probability of a randomly selected hard drive from the company lasting between 2.25 years and 3.25 years? Use the portion of the standard normal table below to help answer the question.

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
