The percent distribution of live multiple-delivery births (three or more babies) in a particular year for women 15 to 54 years old is shown in the pie chart. find each probability. a pie chart labeled "number of multiple births" is divided into seven sectors with labels and approximate sizes as a percentage of a circle as follows: 15-19, 1.3 percent; 20-24, 6.4 percent; 25-29, 21.5 percent; 30-34, 37.5 percent; 35-39, 24.7 percent; 40-44, 5.1 percent; 45-54, 3.5 percent. number of multiple births 15-19 1.3% 20-24 6.4% 25-29 21.5% 30-34 37.5% 35-39 24.7% 40-44 5.1% 45-54 3.5% a. randomly selecting a mother 30-39 years old

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

probability for j is 1/4

while

a is 1/6
