im totally confused by this question
C; You know this because it asks for a dependent event. This means that a first event must occur that automatically changes the results for the following events. When you see dependent, look for without replacement.
Answer:
0.089068 Probability
Step-by-step explanation:
First add the blue and red. So 12+27=39
(12/39)(11/38) =0.089068
You have a 0.089 chance of both of them being red.
You can answer this question by writing the story as a math problem. The sentence tells us step by step what the math problem should be.
We start with $29.60 for parts + (and) 1 1/4 hours (or 1.25) x $56 + (and) $40.
So, 29.60 + 1.25 x 56 + 40= c
c = $139.60
Its a bit tricky to explain without a diagram bot if we take a point (a, b) on the coordinate plane as the center of the circle and another point (x,y) on the circumference then the distance between (a,b) and (x,y) is the radius of the circle.
Now create a triangle by drawing a line horizontally from (a,b) to the circumference and another line prerpendicular to this line from the point (x,y) to make a right angled triangl.e
Applying the pythagoras theorem to this triangle gives
(x - a)^2 + (y - b)^2 = r^2 which is the standard form of equation of a circle.
