Suppose that a disease is inherited via a sexlinked mode of inheritance so that a male offspring has a 50% chance of inheriting the disease, but a female offspring has no chance of inheriting the disease. Further suppose that 51.3% of births are male. What is the probability that a randomly chosen child will be affected by the disease?

There is a 25.65% probability that a randomly chosen child will be affected by the disease.

Step-by-step explanation:

We have these following probabilities:

A 51.3% probability that a child is born male.

A 100-51.3 = 48.7% probability that a child is born female.

A male child has a 50% probability of inheriting the disease.

A female hild has a 0% probability of inheriting the disease.

What is the probability that a randomly chosen child will be affected by the disease?

This is the sum of male who inherits, and female who inherits.

So

There is a 25.65% probability that a randomly chosen child will be affected by the disease.

answer: t=3

step-by-step explanation:

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be
