4c brady is a figure skater. he finds a few of the jumps he does to be difficult, but the rest are easy for him. he must include four jumps in his routine. he always makes the first jump a difficult one. after a difficult jump, there is a 0.2 probability that he'll do another difficult jump, and otherwise he'll do an easy one. after an easy jump, there is a 0.1 probability that he'll do another easy one, and otherwise he'll do a hard one.
what is the probability that the final (fourth) jump of his routine will be an easy one?
what is the probability that all four jumps of his routine will be difficult ones?

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
