Answer:
11:D
12:B
Step-by-step explanation:
Let say that you want to take 1 area. Before the event, the probability of A and B would be:
A= blue and green= (18/12x6) + (18/12x6) = 36/72
B= green and yellow= (18/12x6) + (18/12x6) <span>= 36/72
</span>
If the area that picked is green, then the probability of A and B become
A= blue and green= (18/12x6-1) + (17/12x6-1) = 35/71
B= green and yellow= (17/12x6-1) + (18/12x6-1) = 35/71
Both of the areas of A and B is decreased because they share the probability of green. So A and B would be a dependent event.
Answer:Hello! I have done some research and foung that Jean-Charles de Borda is one of the 72 people who had their names enscribed on the Effiel Tower. He was a mathematician, physicist, and sailor. Hope this helps!!
Step-by-step explanation:
First, you need to use the points to come up with a m (slope). To do this you must use the equation m= y2-y1/x2-x1. label the x in one pair of coordinates x1 and the y, y1. Then label the other x in the other pair of coordinates x2 and the y, y2. use the equation and figure the slope. Next, put the easiest coordinates into point-slope form. The equation you are to use is... y-y1=m(x-x1). Input the values and then distribute the m inside the parenthesis. Then you should be able to do the rest. The final product should be in slope-intercept form.
