If necessary, round all intermediate calculations to four decimal places (e. g. 12.3456). (a) Calculate a point estimate of the mean pull-off force of all connectors in the population (Round the answer to four decimal places (e. g. 90.2353).)
(b) Calculate a point estimate of the pull-off force value that separates the weakest 50% of the connectors in the population from the strongest 50% (Express the answer to two decimal place (e. g. 90.15).)
(c) Calculate the point estimate of the population variance (Round the answer to three decimal places (e. g. 3.567).)
(d) Calculate the point estimate of the population standard deviation (Round the answer to two decimal places (e. g. 1.23).)
(e) Calculate the standard error of the point estimate found in part (a) (Round the answer to two decimal places (e. g. 1.23).)
(f) Calculate a point estimate of the proportion of all connectors in the population whose pull-off force is less than 73 pounds (Round the answer to three decimal places (e. g. 0.123).)

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.

i googled it and this is what i got i don't know how it is. sorry.

(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

i would say b) is your answer

sorry if im wrong
