HELP!!! 1. In a simple random sample of 400 adults, living in the United States, 77 had no health insurance coverage. (a) What are the sample, statistic, population, and parameter for this situation?
(b) Find an 80% confidence interval for the true proportion of adults without health insurance coverage.
(d) what is your margin of error for the confidence interval in part b?
(e) a United States senator claims that at least 25% of all adults do not have health insurance coverage: do you believe this claim? Explain why or why not?

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

beluga wheeeaaalle matt

step-by-step explanation:

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.
