Acollege basketball player makes 80% of his free throws. at the end of a game, his team is losing by two points. he is fouled attempting a three-point shot and is awarded three free throws. assuming free throw attempts are independent, what is the probability that he makes at least two of the free throws?

0.64

Step-by-step explanation:

He makes two from three throws, so he makes three throws or two throws.

We add the probabilities:

0.2*0.8^2+0.8^3

then this is equal to 0.64.

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

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
