When dragons on planet pern lay eggs, the eggs are either green or yellow. the biologists have observed over the years that 23% of the eggs are yellow, and the rest green. next spring the lead scientist has permission to randomly select 68 of the dragon eggs to incubate. consider all the possible samples of 68 dragon eggs.
(a)- what is the usual number of yellow eggs in samples of 68 eggs?
(b)- what is the minimum usual number of yellow eggs?
(c)- what is the maximum usual number of yellow eggs?

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3

∠cbe and ∠deb are same-side interior angles.

i took the test
