Go to artofstat. com, click on WebApps and open the Sampling Distribution for the Sample Proportion app. Under Select Population Proportion (p) change it to 0.8. Note the height of the bar for Success (1) is the same as your value of p, so the height of the bar for Failures (0) has to be 1-p. This value of p represents: a. a statistic or estimator - the proportion of successes computed for the population. b. a statistic or estimator-the proportion of successes computed for the sample. c. a parameter the true proportion of successes in the entire population. d. a parameter the true proportion of successes in the entire sample

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
