Consider the following sample of observations on coating thickness for low-viscosity paint. 0.85 0.88 0.88 1.06 1.09 1.12 1.29 1.31 1.42 1.49 1.59 1.62 1.65 1.71 1.76 1.83 assume that the distribution of coating thickness is normal (a normal probability plot strongly supports this assumption). (a) calculate a point estimate of the mean value of coating thickness. (round your answer to four decimal places.) 1.3469 1.3469

i am unable to solve this problem

step-by-step explanation:

probably .5

i can on others if necessary.

b

step-by-step explanation:

i dont know

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.
